On the contrary. The evidence is quite good.

I have no freaking clue what you are talking about the Earth's magnetic field. For one, it has *NOTHING* to do with global warming.

Read this and this and then get back to me. The magnetosphere blocks solar radiation from penetrating the lower levels of the atmosphere.

About the sun, well, let's see. Sunspots are actually cooler areas of the Sun. So the more sunspots, the cooler the sun!

Read this and then get back to me. Sunspots are indicators of higher solar activity.

You are trolling: Inflection of substantives. Besides, there is no letter V in Greek.

That's news to me. At Tufts, the Network Use Policy allows us to run servers and simply recommends working with TCCS to help things run smoothly (except mail servers -- we need permission for that). Ports are not blocked at all here, and the "policing" of file sharing is limited to responding to specific requests by copyright holders who trace files to our network.

To respond to your broader point, bandwidth isn't only beneficial for file sharing (nor is file sharing only beneficial for copyright infringement and Linux ISO's). Broadcast-quality video conferencing comes to mind, and people in different fields, particularly in academia, can undoubtedly think of many situations where the bandwidth is genuinely useful.

Many (maybe most) experts agree that Eisenhower's Atoms for Peace Iniative helped spread nuclear weapons. It was meant to help other nations learn to use nuclear power for civilian purposes, buy many say that it helped train foreign scientist that would go on to develop nuclear weapons. NPR had a really good story on it

They assume we dump all the nuclear waste into the nation's beer supply
Nobody thinks that. They do think it is inevitable that leaks will occur. It is also well documented that leaks HAVE occurred. hanford, frankfurt, and of course chernoble.

It's like comparing against an oil economy where it's assumed that 99% of the oil is dumped raw into the ocean.
This I agree with. Lovelock may have a point that that fossil fuel would kill more than nuclear fuel. But just dismissing all of the down sides of nuclear power doesn't help your cause. Instead of arguing that nuclear power is totally safe, the better arguement is that it is safer than fossil fuels.

According to the U.S. government, anywhere between $1 million and $6.3 million.

I seem to remember hearing that the U.S. military uses the value of $2 million per soldier. I can't verify that at the moment.

Yes! Please tell us Word 04 also has Unicode support!! If I can go back to copying and pasting ancient Greek text directly from perseus directly into my word processor rather than copying it by hand, I will jump for joy.

Changing World Technologies is the company behind the "turkey guts" thermal depolymerization (TDP) plant in Carthage, MO, USA.

Running some back of the envelope calculations shows some interesting figures. First establish what we use today. In 2002, the United States used an estimated 19.7 million barrels. Per day.

A plant of this size produces 180,000 barrels of oil per year; it is claimed that this is over and above the energy it uses. That works out to 493.15 barrels per day out of 200 tons each day. There are 160 million tons of wood waste per year (1998 figures) alone. That works out to 1,080,876 barrels per day if we assume the same conversion rate of 200 tons of organic matter to 493.15 barrels per day. 5.4% of our daily total oil demand from wood waste alone. Enough to affect prices at the margin, where it counts. At current rates, we will import 68% of our oil by 2025. This same reference cites DOE figures that say we currently import about 50%, or about 10 million barrels. If we put this in place today, the percentage of imports this represents rises to 10.8%.

Pulling our focus back a bit, we find that agriculture produces about 1 billion tons of waste per year. Remember, agricultural waste streams are not the only feedstock; some manufacturing waste streams are also eligible. But for the sake of back of the envelope calculations, let's assume that all eligible waste streams for TDP amounts to 1 billion tons per year. That works out to 6,755,479 barrels per day, or about 67% of daily import demand today.

Even if we project out increased demand for petroleum in the future, the potential for this technique to affect prices at the margin should not be dismissed out of hand. It is highly unlikely that we can use this technique (assuming all the engineering, business and logistical details are worked out --- the reaction chambers need to be calibrated for the feedstock, and they don't have many "recipes" worked out yet, and don't even know what is or is not feasible) to supplant import demand. Fortunately, we don't need it to wholesale replace imports: if we can make it affect the marginal price, that's still a useful tool in our national assets.

If the Changing World folks really are on the up and up, and they produce a small net of oil from these big brother versions of the pilot plant, then this is a strong piece of evidence for the school of thought who contend that market mechanisms will produce solutions as the need arises. As others in this thread have already pointed out, we certainly have nowhere approached the theoretical physics-imposed limits of available energy that can be gathered from the sun.

The following likely has nothing to do with the game, but Hesiod tells us additionally that 'hope' (elpis) was also in the jar, and that was the only thing that didn't escape. About which, scholars for centuries have been re-echoing the title of this thread, WTF??

Atlantis was mentioned by more than Plato. It was in Herodotus' writings as well, and he claimed the Egyptians recorded its existence (he studied in Egypt).

CLXXXIV. Another ten days' journey from the Garamantes there is again a salt hill and water, where men live called Atarantes. These are the only men whom we know who have no names; for the whole people are called Atarantes, but no man has a name of his own. [2] When the sun is high, they curse and very foully revile him, because his burning heat afflicts their people and their land. [3] After another ten days' journey there is again a hill of salt, and water, and men living there. Near to this salt is a mountain called Atlas, whose shape is slender and conical; and it is said to be so high that its heights cannot be seen, for clouds are always on them winter and summer. The people of the country call it the pillar of heaven. [4] These men get their name, which is Atlantes, from this mountain. It is said that they eat no living creature, and see no dreams in their sleep.

I believe about 2000 years ago, the olympic athletes were awarded gold, silver, and bronze medals...

You believe wrongly. The three medals are a modern invention, dating to the 1896 games. The original prizes were olive-branch garlands, and the very valuable respect of your countrymen (including such things as statues, poems composed in your honor, and basically everyone wanting to be your friend). Think of it as being like college sports.

For the real skinny, read a little of Pausanias,
who wrote his "Description of Greece" back when the original Olympics were still being held.

Well, I've never studied church latin very much, being a classicist. I don't see any reason why the church wouldn't use the same language for official purposes as they do in the Mass (other than the Latin Mass being a relatively static document). I'm not sure what you mean by neo-Latin. Having studied the form the Romans used, I tend to compose in classical Latin and I usually avoid Ecclesiastical neologisms.

Check out this site and try looking up some words used in Church latin (try a hymn or the text of the Mass) you'll find that the etymology of some of them will be farily new because Latin vocabulary is changing.

The reason is that our health care industry needs drugs to be patented is because the cost of developing drugs is so high. One study

• Research of the basic idea behind the drug - e.g. this chemical reacts favorably with the thing in the body we're trying to eliminate
• Researching the metabolic pathways - e.g. here's some additional chemicals that we can use to ensure that the active chemicals will reach their destination, without doing any damage
• Animal testing
• Human testing: Phases 1 - 3
• Mass production
• FDA approval
• Marketing

Contrast this with the cost to develop a post-patent generic:

• Analysis of chemical structure of already developed, tested and FDA approved drug.
• Mass production
• Marketing

By far the biggest cost of developing the drug is the R&D. And of that expense, the biggest cost is the clincal human trials. These are costs that post-patent generic companies simply don't have to pay. Without patent protection, we'd end up with a world where the developer of a drug would incur *all* of the costs to develop that drug and the generic manufacturer would gain all of the profits. The drug developer would simply not be able to recover their costs without patents. Patents enable the drug developer to earn the profits from the sale of that drug to cover:

• Research & Development of that drug
• Research & Development of investigatory drugs - drugs that show promise but for some reason don't make it to market

Patents enable the pharmaceuticals to stay in business. I once read (although I can't find it now), that pharmaceuticals develop 200 failed drugs for every 1 drug that makes it to market. Inventing is a hard business, and without some sort of legal protection, we simply wouldn't have it.

Suit yourself, Hanzo. Those elite schools will pass you over for avoiding math much quicker than they will looking at your overall GPA. There is a sure-fire way to avoid that C...HARD WORK. If you aren't good in math, rather than dance around it, get some help! Tutoring and other services are usually available at Community Colleges.

According to the admissions, based on whats on their websites and documentation, a Philosophy or Liberal Arts major is not required to take calculus as a prerequisite, so why should I take it if its not required? Would it really boost me up that much ?

I cant get tutoring because I dont have a car yet, and I dont live on campus because its community college, so this isnt an option, when I live on campus then I can get tutoring.

Perhaps you might have an undiagnosed learning disability that prevents you from "grokking" math. Again, find out about resources available to you and use them.

Math is a prerequisite for SCIENCE degrees only. Show me where it says you MUST take math to be accepted into any of these schools for a philosophy degree? At most I'll need to take an a linear algebra class or a pre calculus class, thats it.

One class is all you must pass in order to get a degree, and I can take this class during the summer and get a C, and get my degree. So tell me why you think it would be a good idea to take it now if none of the schools say its a requirement for acceptance?

If the schools DID say its a required class for acceptance into their philosophy program, I'd take the class, but that would delay me from transfering for another semester so I dont see a point, I think instead i will transfer out of community college into one of the 4 year colleges on the list I showed you, and then take the mathclass, when I actually LIVE on campus and no longer have to worry about traveling for over 2 hours to get to school via public transportation.

Hard work can avoid a C? Actually no it cant, it depends on how good you are at what you are doing. You can work hard and get a C, or you can breeze through a class and get an A, if you are doing something you never were taught in highschool, such as say a student who comes from another country and decided to take a college level english class, theres no way in hell they'd get an A, because they never learned English before, math is the same way, its unrealistic for me to believe I can make up for 12 years of not being taught something, simply by cramming 12 years of work into one semester.

Sure I can pass with a C, but I dont think I'd truely underst

The plural of Venus is Veneres, not Venera. Genus,generis is neuter, and thus has an -a ending for the nominative plural. Venus is not. Thus Venus follows the regular 3rd declension, and has a plural of Veneres.

All neuter plural nominatives in Latin end in -a. This is not the case for any other gender, if I remember correctly.

I believe that section 62 of Allen and Greenough's gives a full description of the declension of such nouns.

Do these government thinktanks that develop the cancer drugs, etc., get the drugs approved? I don't think so. It takes $897 million to get a drug completely through the FDA approval process. Only 21% of drugs submitted to FDA approval make it all the way through.

The people need to realize that the drug approval process pretty much sets the base price of the drug.

Crates also seems connected to Kratos (or power, as in Democracy") so it may mean Horse of Power, or "Strong Horse."

From looking at Perseus, krates looks like an adjectival ending derived from kratos. Hippokrates would, in fact, then mean ``horse-powerful'' or something like that. Pankrates means ``all-powerful'' (similar to Pankrator, a title of Christ); akrates means ``powerless.'' Perseus has a list of words with this ending.

Behe is argumenting from ignorance throughout the whole book, saying that since we cannot figure out how a complex system could have evolved through natural selection, it must be the work of a supreme being. This sort of reasoning can be called many things, science it is not.

Etymology: a. L. virus slimy liquid, poison, offensive odour or taste. Hence also Fr., Sp., Pg. virus.

1 Venom, such as is emitted by a poisonous animal. Also fig.

2 Path. a A morbid principle or poisonous substance produced in the body as the result of some disease, esp. one capable of being introduced into other persons or animals by inoculations or otherwise and of developing the same disease in them. Now superseded by the next sense.

b Pl. viruses. An infectious organism that is usu. submicroscopic, can multiply only inside certain living host cells (in many cases causing disease) and is now understood to be a non-cellular structure lacking any intrinsic metabolism and usually comprising a DNA or RNA core inside a protein coat (see also quot. 1977). [ Formerly referred to as filterable viruses, their first distinguishing characteristic being the ability to pass through filters that retained bacteria. ]

The simple answer is that there wasn't one. The longer answer follows.

Writers who, searching for a fancy plural to virus, incorrectly write *viri are doubtless blindly applying an overreaching -us => -i rule. This mis-inflects many words. For example, status and hiatus only change the length of the final vowel; genus goes to genera; corpus goes to corpora. Others are even worse if this rule is mis-applied, like syllabus, caucus, octopus, mandamus, and rebus.

Anyway, Latin already had a word viri, but it was the nominative plural not of virus (slime, poison, or venom), but of vir (man), which as it turns out is also a 2nd declension noun. I do not believe that writers of English who write viri are intentionally speaking of men. And although there actually is a viri form for virus, it's the genitive singular[1] [slashdot.org], not the nominative plural. And we certainly don't grab for genitive singulars for the plurals when we've started out with a nominative. Such hanky panky would certainly get you talked about, and probably your hand slapped as well.

This apparently invariant use of virus as a genitive singular may also imply that it's 4th declension, as some scholars [slashdot.org] believe.

Those confused souls who write *virii are tacitly positing the existence of the non-word *virius, and declining it as though it were like filius. It's true that l/r are both linguals that sometimes get interchanged, and that f/v are just a change in voicing[2] [slashdot.org], but that's just reaching. *Virii is still completely silly, so don't do that; otherwise, everyone will know you're just a blathering script kiddie.

The crucial problem here is that, classically speaking, there appears to be no recorded use of virus in the plural. It was a 2nd declension noun ending in -us, which is rather common, but it was also a neuter, which is rather rare. I could only come up with three such 2nd declension neuters: virus [tufts.edu] (some poison), pelagus [tufts.edu] (the sea, usually poetically), and vulgus [tufts.edu] (the crowd). None appear to admit plurals. Perhaps this is because they are mass nouns, not count nouns. [3] [slashdot.org]

One citation below wonders whether these -us 2nd declension neuters might have inflected -us => -ora, the way the 3rd declension's neuter plurals for tempus and corpus do. There's really not any support for that notion--that I could find at least. If so, that would end up producing *virora. Most other citations think that these plurals just never happened at all, or that if they did, they didn't jump declensions. Perhaps they were invariant as they oddly are for the vocative and accusative cases. In any event, *virora does not fit comfortably in the mouth of an English speaker, which is a good reason to avoid it.[4] [slashdot.org]

Another theory holds that virus, if it was a 2nd declension neuter, must go to *vira in the plural as do its -um neuter brethren in the 2nd declension. However, that assumes that it works like a -um form, not as a -us form does. And it really seems to do neither. If it were a -us form (again, as a 2nd declension nominative), then its vocative would have to be *vire; but it's really only virus. You also expect an accusative form *viros, but that too is missing; it's still just virus in the accusative. And if it were a -um form, then its vocative would have to be *virum. But it's not--here again, it's only virus. (Vocative examples of virus are not particularly common. Apparently the Romans seldom addressed their slime in a personal fashion. :-)

So what we have here is something of a mixed or invariant declension. Trying to find a plural for something that didn't take a plural (possibly because it was not a count but a mass noun), or at least, one for which no plural is classically attested, is a fruitless endeavour. Best to stick with English and use viruses. Journey Into the Fourth Declension Some scholars, includining Gavin Betts, believe that virus pertained not to the second declension, but to the fourth one. Here is an example or two that support[5] [slashdot.org] Betts and dispute the 2nd declension theory. The first is classical, from Ammianus [geocities.com]:

qui ut coluber copia virus exuberans natorum

Just another note: You must not forget that Ammian's native tongue was Greek, not Latin - so it's (very hypothetical!) possible he understood virus as a so called accusativus respectus and copia as adverbial expression. (A more common phenomenon in Greek.) exuberare was combined that way with lucrum and there was a tendency to use non-transitive verbs in a (active) transitive way - like anhelare or spumare in late antiquity's Latin as well. (The pseudo-Ciceronian Rhetorica ad Herennium's fourth book is an outstanding exception with its usage of anhelans et spumans in the passage about the denarratio and the following example IF one dates it to 80 a.Chr.n. ...) But - to make a conclusion - it's not classical at all to use the form viri(i), because there isn't any genitive-singular- or nominative-plural-form (*) viri found in the whole Latin literature up to the first century p.Chr.n. as far as PHI-CD-Rom can tell :-)

Here's what other sources have to say about this matter:

alt.usage.english FAQ [ccp14.ac.uk] Not all Latin words ending in -us had plurals in -i. Apparatus, cantus, coitus, hiatus, impetus, Jesus, nexus, plexus, prospectus, and status were 4th declension in Latin, and had plurals in -us with a long `u'. Corpus, genus, and opus were 3rd declension, with plurals corpora, genera, and opera. Virus is not attested in the plural in Latin, and is of a rare form (2nd declension neuter in -us) that makes it debatable what the Latin plural would have been; the only plural in English is viruses. Omnibus and rebus were not nominative nouns in Latin. Ignoramus was not a noun in Latin.

[...] classical plurals [...] [ilhawaii.net] What is the plural of virus? This neuter in Latin lacked a plural; it would presumably [disputable -tchrist ] have been virora like corpora, the plural of neuter corpus. (Like corpora, virora would be stressed on its initial syllable. As indicated earlier, *corpi would be as outlandish--as far beyond the pale--as *rhinoceri and *octopi.)

Latin had several declensions containing neuter, feminine, and masculine words ending in -us; the plurals are different in each one. Incidentally, the singular of mores (pronounced `moh-rehs') is mos, with the same change of `s' to `r' between vowels heard in corpus : corpora and in genus : genera.

Allen and Greenough [tufts.edu] The authors at the cited reference point out the follwoing:

Many Greek nouns retain their original gender: as, arctus (F.), the Polar Bear; methodus (F.), method.

a. The following in -us are Neuter; their accusative (as with all neuters) is the same as the nominative: pelagus, sea; virus, poison; vulgus (rarely M.), the crowd. They are not found in the plural, except pelagus, which has a rare nominative and accusative plural pelage.

NOTE.--The nominative plural neuter cete, sea monsters, occurs; the nominative singular cetus occurs in Vitruvius.

/* Begin Excerpt */

Numerous Latin words have been taken over into the modern scientific vocabulary, most without difficulty. The Latin word virus, however, presents a minor but interesting problem, if one wishes to express a phrase such as Index of Viruses in its Latin form. By analogy with other nouns, one would expect the normal Latin equivalent to be Index Virorum. The difficulty stems from the fact that the Latin noun virus is defective, i.e. does not have a full set of case--forms, singular and plural. The Roman grammarian Priscian (fl. 500 A.D.) states that some claim the word is indeclinable (i.e., has only one form for all the cases in the singular); others, apparently more accurately, that it is declined in the singular according to the second declension neuter and cite two passages from the poet Lucretius in substantiation. All of the ancient grammarians are in agreement, however, that the word is used in the singular only, which indeed appears to be true, for no plural forms are attested in extant Latin works.

In antiquity the word virus had not yet acquired, of course, its current scientific meaning; rather it denoted something like toxicity, venom, a poisonous, deleterious, or unpleasant agent or principle, or poison in the abstract or general sense. (The first meaning given for this word, a slimy liquid, slime, in the most widely used Latin-English dictionaries is inaccurate; the error has been corrected in the more recent Oxford Latin Dictionary.) Nouns denoting entities that are countable pluralize (book, books); nouns denoting noncountable entities do not (except under special circumstances) pluralize (air, mood, valor). The term virus in antiquity appears to have belonged to the latter category, hence the nonexistence of plural forms.

When the word was taken over into modern languages and acquired its current scientific meaning, it changed categories and denoted a countable entity. The modern languages which have adopted the word each pluralize it in their own fashion (e.g., Eng. viruses, Germ. Viren; French and Italian do not distinguish in form between singular and plural, virus). But what to do in neo-Latin, which normally is subject to the rules and constraints of classical Latin?

W. T. Steam in his manual on botanical Latin (Botanical Latin, Newton Abbey, 2nd ed., 1973) gives what would be the normal plural forms of such a second declension neuter noun: nominative vira, genitive virorum, without, however, indicating his authority for those forms. It may be observed that in Latin as in other languages when the plural of noncountable nouns does occur, it generally denotes various kinds of the entity (e.g., wine, honey, oil). Steam may have applied this principle to virus in order to meet the requirements of modern scientific terminology. If Latin had continued to be the common international language of scholars and scientists at the time that viruses were first identified, it appears likely that it would have generated the forms adduced by Steam.

On the Presence of a Plural of the Latin Noun "Virus"

With interest I read the contribution `On the Absence of a Plural of the Latin Noun ``Virus''' in the June 1999 ASM News, p. 388, by Robert J. Smutny. However, according to my Latin grammar, one of the very few books of my gymnasium (high school) days that is still up to date, the plural of the noun virus in Latin is, like the plural nowadays used for virus in Romance languages (e.g., Italian and French), also virus. The Latin noun virus does not belong to the second declension group but, like the noun fructus, meaning fruit or piece of fruit, belongs to a group of Latin words that is declined according to the fourth declension. Hence, two pieces of fruit is in Latin duo fructus and two viruses would be duo virus. According to the fourth declension the plural genitive of virus in Latin is viruum and therefore an Index of Viruses is in Latin an Index Viruum. Virorum is the plural genitive of the Latin noun vir (second declension) meaning man or husband. Consequently an Index Virorum would indicate a list of husbands or men.

Moreover, because the noun virus belongs to the fourth declension group the study of viruses should have been called virulogy and people practicing that science virulogists. My former professor in virology at veterinary school consequently called himself a virulogist and he lectured virulogy. I am afraid that these words have become extinct since he died.

It is important to realize that Latin and Greek derived expressions in biomedical English have been coined by scientists for convenience and not by scholars based on classical grammar. The old Romans might have said to these scientists modulating their language: ``Ut desint vires, tamen est laudanda voluntas,'' which means freely translated: ``Despite your lack of knowledge, still appreciated.''

Etymology: a. L. virus slimy liquid, poison, offensive odour or taste. Hence also Fr., Sp., Pg. virus.

1 Venom, such as is emitted by a poisonous animal. Also fig.

2 Path. a A morbid principle or poisonous substance produced in the body as the result of some disease, esp. one capable of being introduced into other persons or animals by inoculations or otherwise and of developing the same disease in them. Now superseded by the next sense.

b Pl. viruses. An infectious organism that is usu. submicroscopic, can multiply only inside certain living host cells (in many cases causing disease) and is now understood to be a non-cellular structure lacking any intrinsic metabolism and usually comprising a DNA or RNA core inside a protein coat (see also quot. 1977). [ Formerly referred to as filterable viruses, their first distinguishing characteristic being the ability to pass through filters that retained bacteria. ]

The simple answer is that there wasn't one. The longer answer follows.

Writers who, searching for a fancy plural to virus, incorrectly write *viri are doubtless blindly applying an overreaching -us => -i rule. This mis-inflects many words. For example, status and hiatus only change the length of the final vowel; genus goes to genera; corpus goes to corpora. Others are even worse if this rule is mis-applied, like syllabus, caucus, octopus, mandamus, and rebus.

Anyway, Latin already had a word viri, but it was the nominative plural not of virus (slime, poison, or venom), but of vir (man), which as it turns out is also a 2nd declension noun. I do not believe that writers of English who write viri are intentionally speaking of men. And although there actually is a viri form for virus, it's the genitive singular[1] [slashdot.org], not the nominative plural. And we certainly don't grab for genitive singulars for the plurals when we've started out with a nominative. Such hanky panky would certainly get you talked about, and probably your hand slapped as well.

This apparently invariant use of virus as a genitive singular may also imply that it's 4th declension, as some scholars [slashdot.org] believe.

Those confused souls who write *virii are tacitly positing the existence of the non-word *virius, and declining it as though it were like filius. It's true that l/r are both linguals that sometimes get interchanged, and that f/v are just a change in voicing[2] [slashdot.org], but that's just reaching. *Virii is still completely silly, so don't do that; otherwise, everyone will know you're just a blathering script kiddie.

The crucial problem here is that, classically speaking, there appears to be no recorded use of virus in the plural. It was a 2nd declension noun ending in -us, which is rather common, but it was also a neuter, which is rather rare. I could only come up with three such 2nd declension neuters: virus [tufts.edu] (some poison), pelagus [tufts.edu] (the sea, usually poetically), and vulgus [tufts.edu] (the crowd). None appear to admit plurals. Perhaps this is because they are mass nouns, not count nouns. [3] [slashdot.org]

One citation below wonders whether these -us 2nd declension neuters might have inflected -us => -ora, the way the 3rd declension's neuter plurals for tempus and corpus do. There's really not any support for that notion--that I could find at least. If so, that would end up producing *virora. Most other citations think that these plurals just never happened at all, or that if they did, they didn't jump declensions. Perhaps they were invariant as they oddly are for the vocative and accusative cases. In any event, *virora does not fit comfortably in the mouth of an English speaker, which is a good reason to avoid it.[4] [slashdot.org]

Another theory holds that virus, if it was a 2nd declension neuter, must go to *vira in the plural as do its -um neuter brethren in the 2nd declension. However, that assumes that it works like a -um form, not as a -us form does. And it really seems to do neither. If it were a -us form (again, as a 2nd declension nominative), then its vocative would have to be *vire; but it's really only virus. You also expect an accusative form *viros, but that too is missing; it's still just virus in the accusative. And if it were a -um form, then its vocative would have to be *virum. But it's not--here again, it's only virus. (Vocative examples of virus are not particularly common. Apparently the Romans seldom addressed their slime in a personal fashion. :-)

So what we have here is something of a mixed or invariant declension. Trying to find a plural for something that didn't take a plural (possibly because it was not a count but a mass noun), or at least, one for which no plural is classically attested, is a fruitless endeavour. Best to stick with English and use viruses. Journey Into the Fourth Declension Some scholars, includining Gavin Betts, believe that virus pertained not to the second declension, but to the fourth one. Here is an example or two that support[5] [slashdot.org] Betts and dispute the 2nd declension theory. The first is classical, from Ammianus [geocities.com]:

qui ut coluber copia virus exuberans natorum

Just another note: You must not forget that Ammian's native tongue was Greek, not Latin - so it's (very hypothetical!) possible he understood virus as a so called accusativus respectus and copia as adverbial expression. (A more common phenomenon in Greek.) exuberare was combined that way with lucrum and there was a tendency to use non-transitive verbs in a (active) transitive way - like anhelare or spumare in late antiquity's Latin as well. (The pseudo-Ciceronian Rhetorica ad Herennium's fourth book is an outstanding exception with its usage of anhelans et spumans in the passage about the denarratio and the following example IF one dates it to 80 a.Chr.n. ...) But - to make a conclusion - it's not classical at all to use the form viri(i), because there isn't any genitive-singular- or nominative-plural-form (*) viri found in the whole Latin literature up to the first century p.Chr.n. as far as PHI-CD-Rom can tell :-)

Here's what other sources have to say about this matter:

alt.usage.english FAQ [ccp14.ac.uk] Not all Latin words ending in -us had plurals in -i. Apparatus, cantus, coitus, hiatus, impetus, Jesus, nexus, plexus, prospectus, and status were 4th declension in Latin, and had plurals in -us with a long `u'. Corpus, genus, and opus were 3rd declension, with plurals corpora, genera, and opera. Virus is not attested in the plural in Latin, and is of a rare form (2nd declension neuter in -us) that makes it debatable what the Latin plural would have been; the only plural in English is viruses. Omnibus and rebus were not nominative nouns in Latin. Ignoramus was not a noun in Latin.

[...] classical plurals [...] [ilhawaii.net] What is the plural of virus? This neuter in Latin lacked a plural; it would presumably [disputable -tchrist ] have been virora like corpora, the plural of neuter corpus. (Like corpora, virora would be stressed on its initial syllable. As indicated earlier, *corpi would be as outlandish--as far beyond the pale--as *rhinoceri and *octopi.)

Latin had several declensions containing neuter, feminine, and masculine words ending in -us; the plurals are different in each one. Incidentally, the singular of mores (pronounced `moh-rehs') is mos, with the same change of `s' to `r' between vowels heard in corpus : corpora and in genus : genera.

Allen and Greenough [tufts.edu] The authors at the cited reference point out the follwoing:

Many Greek nouns retain their original gender: as, arctus (F.), the Polar Bear; methodus (F.), method.

a. The following in -us are Neuter; their accusative (as with all neuters) is the same as the nominative: pelagus, sea; virus, poison; vulgus (rarely M.), the crowd. They are not found in the plural, except pelagus, which has a rare nominative and accusative plural pelage.

NOTE.--The nominative plural neuter cete, sea monsters, occurs; the nominative singular cetus occurs in Vitruvius.

/* Begin Excerpt */

Numerous Latin words have been taken over into the modern scientific vocabulary, most without difficulty. The Latin word virus, however, presents a minor but interesting problem, if one wishes to express a phrase such as Index of Viruses in its Latin form. By analogy with other nouns, one would expect the normal Latin equivalent to be Index Virorum. The difficulty stems from the fact that the Latin noun virus is defective, i.e. does not have a full set of case--forms, singular and plural. The Roman grammarian Priscian (fl. 500 A.D.) states that some claim the word is indeclinable (i.e., has only one form for all the cases in the singular); others, apparently more accurately, that it is declined in the singular according to the second declension neuter and cite two passages from the poet Lucretius in substantiation. All of the ancient grammarians are in agreement, however, that the word is used in the singular only, which indeed appears to be true, for no plural forms are attested in extant Latin works.

In antiquity the word virus had not yet acquired, of course, its current scientific meaning; rather it denoted something like toxicity, venom, a poisonous, deleterious, or unpleasant agent or principle, or poison in the abstract or general sense. (The first meaning given for this word, a slimy liquid, slime, in the most widely used Latin-English dictionaries is inaccurate; the error has been corrected in the more recent Oxford Latin Dictionary.) Nouns denoting entities that are countable pluralize (book, books); nouns denoting noncountable entities do not (except under special circumstances) pluralize (air, mood, valor). The term virus in antiquity appears to have belonged to the latter category, hence the nonexistence of plural forms.

When the word was taken over into modern languages and acquired its current scientific meaning, it changed categories and denoted a countable entity. The modern languages which have adopted the word each pluralize it in their own fashion (e.g., Eng. viruses, Germ. Viren; French and Italian do not distinguish in form between singular and plural, virus). But what to do in neo-Latin, which normally is subject to the rules and constraints of classical Latin?

W. T. Steam in his manual on botanical Latin (Botanical Latin, Newton Abbey, 2nd ed., 1973) gives what would be the normal plural forms of such a second declension neuter noun: nominative vira, genitive virorum, without, however, indicating his authority for those forms. It may be observed that in Latin as in other languages when the plural of noncountable nouns does occur, it generally denotes various kinds of the entity (e.g., wine, honey, oil). Steam may have applied this principle to virus in order to meet the requirements of modern scientific terminology. If Latin had continued to be the common international language of scholars and scientists at the time that viruses were first identified, it appears likely that it would have generated the forms adduced by Steam.

Numerous Latin words have been taken over into the modern scientific vocabulary, most without difficulty. The Latin word virus, however, presents a minor but interesting problem, if one wishes to express a phrase such as Index of Viruses in its Latin form. By analogy with other nouns, one would expect the normal Latin equivalent to be Index Virorum. The difficulty stems from the fact that the Latin noun virus is defective, i.e. does not have a full set of case--forms, singular and plural. The Roman grammarian Priscian (fl. 500 A.D.) states that some claim the word is indeclinable (i.e., has only one form for all the cases in the singular); others, apparently more accurately, that it is declined in the singular according to the second declension neuter and cite two passages from the poet Lucretius in substantiation. All of the ancient grammarians are in agreement, however, that the word is used in the singular only, which indeed appears to be true, for no plural forms are attested in extant Latin works.

In antiquity the word virus had not yet acquired, of course, its current scientific meaning; rather it denoted something like toxicity, venom, a poisonous, deleterious, or unpleasant agent or principle, or poison in the abstract or general sense. (The first meaning given for this word, a slimy liquid, slime, in the most widely used Latin-English dictionaries is inaccurate; the error has been corrected in the more recent Oxford Latin Dictionary.) Nouns denoting entities that are countable pluralize (book, books); nouns denoting noncountable entities do not (except under special circumstances) pluralize (air, mood, valor). The term virus in antiquity appears to have belonged to the latter category, hence the nonexistence of plural forms.

When the word was taken over into modern languages and acquired its current scientific meaning, it changed categories and denoted a countable entity. The modern languages which have adopted the word each pluralize it in their own fashion (e.g., Eng. viruses, Germ. Viren; French and Italian do not distinguish in form between singular and plural, virus). But what to do in neo-Latin, which normally is subject to the rules and constraints of classical Latin?

W. T. Steam in his manual on botanical Latin (Botanical Latin, Newton Abbey, 2nd ed., 1973) gives what would be the normal plural forms of such a second declension neuter noun: nominative vira, genitive virorum, without, however, indicating his authority for those forms. It may be observed that in Latin as in other languages when the plural of noncountable nouns does occur, it generally denotes various kinds of the entity (e.g., wine, honey, oil). Steam may have applied this principle to virus in order to meet the requirements of modern scientific terminology. If Latin had continued to be the common international language of scholars and scientists at the time that viruses were first identified, it appears likely that it would have generated the forms adduced by Steam.

On the Presence of a Plural of the Latin Noun "Virus"

With interest I read the contribution `On the Absence of a Plural of the Latin Noun ``Virus''' in the June 1999 ASM News, p. 388, by Robert J. Smutny. However, according to my Latin grammar, one of the very few books of my gymnasium (high school) days that is still up to date, the plural of the noun virus in Latin is, like the plural nowadays used for virus in Romance languages (e.g., Italian and French), also virus. The Latin noun virus does not belong to the second declension group but, like the noun fructus, meaning fruit or piece of fruit, belongs to a group of Latin words that is declined according to the fourth declension. Hence, two pieces of fruit is in Latin duo fructus and two viruses would be duo virus. According to the fourth declension the plural genitive of virus in Latin is viruum and therefore an Index of Viruses is in Latin an Index Viruum. Virorum is the plural genitive of the Latin noun vir (second declension) meaning man or husband. Consequently an Index Virorum would indicate a list of husbands or men.

Moreover, because the noun virus belongs to the fourth declension group the study of viruses should have been called virulogy and people practicing that science virulogists. My former professor in virology at veterinary school consequently called himself a virulogist and he lectured virulogy. I am afraid that these words have become extinct since he died.

It is important to realize that Latin and Greek derived expressions in biomedical English have been coined by scientists for convenience and not by scholars based on classical grammar. The old Romans might have said to these scientists modulating their language: ``Ut desint vires, tamen est laudanda voluntas,'' which means freely translated: ``Despite your lack of knowledge, still appreciated.''

Etymology: a. L. virus slimy liquid, poison, offensive odour or taste. Hence also Fr., Sp., Pg. virus.

1 Venom, such as is emitted by a poisonous animal. Also fig.

2 Path. a A morbid principle or poisonous substance produced in the body as the result of some disease, esp. one capable of being introduced into other persons or animals by inoculations or otherwise and of developing the same disease in them. Now superseded by the next sense.

b Pl. viruses. An infectious organism that is usu. submicroscopic, can multiply only inside certain living host cells (in many cases causing disease) and is now understood to be a non-cellular structure lacking any intrinsic metabolism and usually comprising a DNA or RNA core inside a protein coat (see also quot. 1977). [ Formerly referred to as filterable viruses, their first distinguishing characteristic being the ability to pass through filters that retained bacteria. ]

The simple answer is that there wasn't one. The longer answer follows.

Writers who, searching for a fancy plural to virus, incorrectly write *viri are doubtless blindly applying an overreaching -us => -i rule. This mis-inflects many words. For example, status and hiatus only change the length of the final vowel; genus goes to genera; corpus goes to corpora. Others are even worse if this rule is mis-applied, like syllabus, caucus, octopus, mandamus, and rebus.

Anyway, Latin already had a word viri, but it was the nominative plural not of virus (slime, poison, or venom), but of vir (man), which as it turns out is also a 2nd declension noun. I do not believe that writers of English who write viri are intentionally speaking of men. And although there actually is a viri form for virus, it's the genitive singular[1] [slashdot.org], not the nominative plural. And we certainly don't grab for genitive singulars for the plurals when we've started out with a nominative. Such hanky panky would certainly get you talked about, and probably your hand slapped as well.

This apparently invariant use of virus as a genitive singular may also imply that it's 4th declension, as some scholars [slashdot.org] believe.

Those confused souls who write *virii are tacitly positing the existence of the non-word *virius, and declining it as though it were like filius. It's true that l/r are both linguals that sometimes get interchanged, and that f/v are just a change in voicing[2] [slashdot.org], but that's just reaching. *Virii is still completely silly, so don't do that; otherwise, everyone will know you're just a blathering script kiddie.

The crucial problem here is that, classically speaking, there appears to be no recorded use of virus in the plural. It was a 2nd declension noun ending in -us, which is rather common, but it was also a neuter, which is rather rare. I could only come up with three such 2nd declension neuters: virus [tufts.edu] (some poison), pelagus [tufts.edu] (the sea, usually poetically), and vulgus [tufts.edu] (the crowd). None appear to admit plurals. Perhaps this is because they are mass nouns, not count nouns. [3] [slashdot.org]

One citation below wonders whether these -us 2nd declension neuters might have inflected -us => -ora, the way the 3rd declension's neuter plurals for tempus and corpus do. There's really not any support for that notion--that I could find at least. If so, that would end up producing *virora. Most other citations think that these plurals just never happened at all, or that if they did, they didn't jump declensions. Perhaps they were invariant as they oddly are for the vocative and accusative cases. In any event, *virora does not fit comfortably in the mouth of an English speaker, which is a good reason to avoid it.[4] [slashdot.org]

Another theory holds that virus, if it was a 2nd declension neuter, must go to *vira in the plural as do its -um neuter brethren in the 2nd declension. However, that assumes that it works like a -um form, not as a -us form does. And it really seems to do neither. If it were a -us form (again, as a 2nd declension nominative), then its vocative would have to be *vire; but it's really only virus. You also expect an accusative form *viros, but that too is missing; it's still just virus in the accusative. And if it were a -um form, then its vocative would have to be *virum. But it's not--here again, it's only virus. (Vocative examples of virus are not particularly common. Apparently the Romans seldom addressed their slime in a personal fashion. :-)

So what we have here is something of a mixed or invariant declension. Trying to find a plural for something that didn't take a plural (possibly because it was not a count but a mass noun), or at least, one for which no plural is classically attested, is a fruitless endeavour. Best to stick with English and use viruses. Journey Into the Fourth Declension Some scholars, includining Gavin Betts, believe that virus pertained not to the second declension, but to the fourth one. Here is an example or two that support[5] [slashdot.org] Betts and dispute the 2nd declension theory. The first is classical, from Ammianus [geocities.com]:

qui ut coluber copia virus exuberans natorum

Just another note: You must not forget that Ammian's native tongue was Greek, not Latin - so it's (very hypothetical!) possible he understood virus as a so called accusativus respectus and copia as adverbial expression. (A more common phenomenon in Greek.) exuberare was combined that way with lucrum and there was a tendency to use non-transitive verbs in a (active) transitive way - like anhelare or spumare in late antiquity's Latin as well. (The pseudo-Ciceronian Rhetorica ad Herennium's fourth book is an outstanding exception with its usage of anhelans et spumans in the passage about the denarratio and the following example IF one dates it to 80 a.Chr.n. ...) But - to make a conclusion - it's not classical at all to use the form viri(i), because there isn't any genitive-singular- or nominative-plural-form (*) viri found in the whole Latin literature up to the first century p.Chr.n. as far as PHI-CD-Rom can tell :-)

Here's what other sources have to say about this matter:

alt.usage.english FAQ [ccp14.ac.uk] Not all Latin words ending in -us had plurals in -i. Apparatus, cantus, coitus, hiatus, impetus, Jesus, nexus, plexus, prospectus, and status were 4th declension in Latin, and had plurals in -us with a long `u'. Corpus, genus, and opus were 3rd declension, with plurals corpora, genera, and opera. Virus is not attested in the plural in Latin, and is of a rare form (2nd declension neuter in -us) that makes it debatable what the Latin plural would have been; the only plural in English is viruses. Omnibus and rebus were not nominative nouns in Latin. Ignoramus was not a noun in Latin.

[...] classical plurals [...] [ilhawaii.net] What is the plural of virus? This neuter in Latin lacked a plural; it would presumably [disputable -tchrist ] have been virora like corpora, the plural of neuter corpus. (Like corpora, virora would be stressed on its initial syllable. As indicated earlier, *corpi would be as outlandish--as far beyond the pale--as *rhinoceri and *octopi.)

Latin had several declensions containing neuter, feminine, and masculine words ending in -us; the plurals are different in each one. Incidentally, the singular of mores (pronounced `moh-rehs') is mos, with the same change of `s' to `r' between vowels heard in corpus : corpora and in genus : genera.

Allen and Greenough [tufts.edu] The authors at the cited reference point out the follwoing:

Many Greek nouns retain their original gender: as, arctus (F.), the Polar Bear; methodus (F.), method.

a. The following in -us are Neuter; their accusative (as with all neuters) is the same as the nominative: pelagus, sea; virus, poison; vulgus (rarely M.), the crowd. They are not found in the plural, except pelagus, which has a rare nominative and accusative plural pelage.

NOTE.--The nominative plural neuter cete, sea monsters, occurs; the nominative singular cetus occurs in Vitruvius.

But - to make a conclusion - it's not classical at all to use the form viri(i), because there isn't any genitive-singular- or nominative-plural-form (*) viri found in the whole Latin literature up to the first century p.Chr.n. as far as PHI-CD-Rom can tell :-)

Here's what other sources have to say about this matter:

alt.usage.english FAQ [ccp14.ac.uk] Not all Latin words ending in -us had plurals in -i. Apparatus, cantus, coitus, hiatus, impetus, Jesus, nexus, plexus, prospectus, and status were 4th declension in Latin, and had plurals in -us with a long `u'. Corpus, genus, and opus were 3rd declension, with plurals corpora, genera, and opera. Virus is not attested in the plural in Latin, and is of a rare form (2nd declension neuter in -us) that makes it debatable what the Latin plural would have been; the only plural in English is viruses. Omnibus and rebus were not nominative nouns in Latin. Ignoramus was not a noun in Latin.

Latin had several declensions containing neuter, feminine, and masculine words ending in -us; the plurals are different in each one.

Numerous Latin words have been taken over into the modern scientific vocabulary, most without difficulty. The Latin word virus, however, presents a minor but interesting problem, if one wishes to express a phrase such as Index of Viruses in its Latin form. By analogy with other nouns, one would expect the normal Latin equivalent to be Index Virorum. The difficulty stems from the fact that the Latin noun virus is defective, i.e. does not have a full set of case--forms, singular and plural. The Roman grammarian Priscian (fl. 500 A.D.) states that some claim the word is indeclinable (i.e., has only one form for all the cases in the singular); others, apparently more accurately, that it is declined in the singular according to the second declension neuter and cite two passages from the poet Lucretius in substantiation. All of the ancient grammarians are in agreement, however, that the word is used in the singular only, which indeed appears to be true, for no plural forms are attested in extant Latin works.

In antiquity the word virus had not yet acquired, of course, its current scientific meaning; rather it denoted something like toxicity, venom, a poisonous, deleterious, or unpleasant agent or principle, or poison in the abstract or general sense. (The first meaning given for this word, a slimy liquid, slime, in the most widely used Latin-English dictionaries is inaccurate; the error has been corrected in the more recent Oxford Latin Dictionary.) Nouns denoting entities that are countable pluralize (book, books); nouns denoting noncountable entities do not (except under special circumstances) pluralize (air, mood, valor). The term virus in antiquity appears to have belonged to the latter category, hence the nonexistence of plural forms.

When the word was taken over into modern languages and acquired its current scientific meaning, it changed categories and denoted a countable entity. The modern languages which have adopted the word each pluralize it in their own fashion (e.g., Eng. viruses, Germ. Viren; French and Italian do not distinguish in form between singular and plural, virus). But what to do in neo-Latin, which normally is subject to the rules and constraints of classical Latin?

W. T. Steam in his manual on botanical Latin (Botanical Latin, Newton Abbey, 2nd ed., 1973) gives what would be the normal plural forms of such a second declension neuter noun: nominative vira, genitive virorum, without, however, indicating his authority for those forms. It may be observed that in Latin as in other languages when the plural of noncountable nouns does occur, it generally denotes various kinds of the entity (e.g., wine, honey, oil). Steam may have applied this principle to virus in order to meet the requirements of modern scientific terminology. If Latin had continued to be the common international language of scholars and scientists at the time that viruses were first identified, it appears likely that it would have generated the forms adduced by Steam.

On the Presence of a Plural of the Latin Noun "Virus"

With interest I read the contribution `On the Absence of a Plural of the Latin Noun ``Virus''' in the June 1999 ASM News, p. 388, by Robert J. Smutny. However, according to my Latin grammar, one of the very few books of my gymnasium (high school) days that is still up to date, the plural of the noun virus in Latin is, like the plural nowadays used for virus in Romance languages (e.g., Italian and French), also virus. The Latin noun virus does not belong to the second declension group but, like the noun fructus, meaning fruit or piece of fruit, belongs to a group of Latin words that is declined according to the fourth declension. Hence, two pieces of fruit is in Latin duo fructus and two viruses would be duo virus. According to the fourth declension the plural genitive of virus in Latin is viruum and therefore an Index of Viruses is in Latin an Index Viruum. Virorum is the plural genitive of the Latin noun vir (second declension) meaning man or husband. Consequently an Index Virorum would indicate a list of husbands or men.

Moreover, because the noun virus belongs to the fourth declension group the study of viruses should have been called virulogy and people practicing that science virulogists. My former professor in virology at veterinary school consequently called himself a virulogist and he lectured virulogy. I am afraid that these words have become extinct since he died.

It is important to realize that Latin and Greek derived expressions in biomedical English have been coined by scientists for convenience and not by scholars based on classical grammar. The old Romans might have said to these scientists modulating their language: ``Ut desint vires, tamen est laudanda voluntas,'' which means freely translated: ``Despite your lack of knowledge, still appreciated.''

Etymology: a. L. virus slimy liquid, poison, offensive odour or taste. Hence also Fr., Sp., Pg. virus.

1 Venom, such as is emitted by a poisonous animal. Also fig.

2 Path. a A morbid principle or poisonous substance produced in the body as the result of some disease, esp. one capable of being introduced into other persons or animals by inoculations or otherwise and of developing the same disease in them. Now superseded by the next sense.

b Pl. viruses. An infectious organism that is usu. submicroscopic, can multiply only inside certain living host cells (in many cases causing disease) and is now understood to be a non-cellular structure lacking any intrinsic metabolism and usually comprising a DNA or RNA core inside a protein coat (see also quot. 1977). [ Formerly referred to as filterable viruses, their first distinguishing characteristic being the ability to pass through filters that retained bacteria. ]

The simple answer is that there wasn't one. The longer answer follows.

Writers who, searching for a fancy plural to virus, incorrectly write *viri are doubtless blindly applying an overreaching -us => -i rule. This mis-inflects many words. For example, status and hiatus only change the length of the final vowel; genus goes to genera; corpus goes to corpora. Others are even worse if this rule is mis-applied, like syllabus, caucus, octopus, mandamus, and rebus.

Anyway, Latin already had a word viri, but it was the nominative plural not of virus (slime, poison, or venom), but of vir (man), which as it turns out is also a 2nd declension noun. I do not believe that writers of English who write viri are intentionally speaking of men. And although there actually is a viri form for virus, it's the genitive singular[1] [slashdot.org], not the nominative plural. And we certainly don't grab for genitive singulars for the plurals when we've started out with a nominative. Such hanky panky would certainly get you talked about, and probably your hand slapped as well.

This apparently invariant use of virus as a genitive singular may also imply that it's 4th declension, as some scholars [slashdot.org] believe.

Those confused souls who write *virii are tacitly positing the existence of the non-word *virius, and declining it as though it were like filius. It's true that l/r are both linguals that sometimes get interchanged, and that f/v are just a change in voicing[2] [slashdot.org], but that's just reaching. *Virii is still completely silly, so don't do that; otherwise, everyone will know you're just a blathering script kiddie.

The crucial problem here is that, classically speaking, there appears to be no recorded use of virus in the plural. It was a 2nd declension noun ending in -us, which is rather common, but it was also a neuter, which is rather rare. I could only come up with three such 2nd declension neuters: virus [tufts.edu] (some poison), pelagus [tufts.edu] (the sea, usually poetically), and vulgus [tufts.edu] (the crowd). None appear to admit plurals. Perhaps this is because they are mass nouns, not count nouns. [3] [slashdot.org]

One citation below wonders whether these -us 2nd declension neuters might have inflected -us => -ora, the way the 3rd declension's neuter plurals for tempus and corpus do. There's really not any support for that notion--that I could find at least. If so, that would end up producing *virora. Most other citations think that these plurals just never happened at all, or that if they did, they didn't jump declensions. Perhaps they were invariant as they oddly are for the vocative and accusative cases. In any event, *virora does not fit comfortably in the mouth of an English speaker, which is a good reason to avoid it.[4] [slashdot.org]

Another theory holds that virus, if it was a 2nd declension neuter, must go to *vira in the plural as do its -um neuter brethren in the 2nd declension. However, that assumes that it works like a -um form, not as a -us form does. And it really seems to do neither. If it were a -us form (again, as a 2nd declension nominative), then its vocative would have to be *vire; but it's really only virus. You also expect an accusative form *viros, but that too is missing; it's still just virus in the accusative. And if it were a -um form, then its vocative would have to be *virum. But it's not--here again, it's only virus. (Vocative examples of virus are not particularly common. Apparently the Romans seldom addressed their slime in a personal fashion. :-)

So what we have here is something of a mixed or invariant declension. Trying to find a plural for something that didn't take a plural (possibly because it was not a count but a mass noun), or at least, one for which no plural is classically attested, is a fruitless endeavour. Best to stick with English and use viruses. Journey Into the Fourth Declension Some scholars, includining Gavin Betts, believe that virus pertained not to the second declension, but to the fourth one. Here is an example or two that support[5] [slashdot.org] Betts and dispute the 2nd declension theory. The first is classical, from Ammianus [geocities.com]:

qui ut coluber copia virus exuberans natorum

Just another note: You must not forget that Ammian's native tongue was Greek, not Latin - so it's (very hypothetical!) possible he understood virus as a so called accusativus respectus and copia as adverbial expression. (A more common phenomenon in Greek.) exuberare was combined that way with lucrum and there was a tendency to use non-transitive verbs in a (active) transitive way - like anhelare or spumare in late antiquity's Latin as well. (The pseudo-Ciceronian Rhetorica ad Herennium's fourth book is an outstanding exception with its usage of anhelans et spumans in the passage about the denarratio and the following example IF one dates it to 80 a.Chr.n. ...) But - to make a conclusion - it's not classical at all to use the form viri(i), because there isn't any genitive-singular- or nominative-plural-form (*) viri found in the whole Latin literature up to the first century p.Chr.n. as far as PHI-CD-Rom can tell :-)

Here's what other sources have to say about this matter:

alt.usage.english FAQ [ccp14.ac.uk] Not all Latin words ending in -us had plurals in -i. Apparatus, cantus, coitus, hiatus, impetus, Jesus, nexus, plexus, prospectus, and status were 4th declension in Latin, and had plurals in -us with a long `u'.

In any event, *virora does not fit comfortably in the mouth of an English speaker, which is a good reason to avoid it.[4] [slashdot.org]

Another theory holds that virus, if it was a 2nd declension neuter, must go to *vira in the plural as do its -um neuter brethren in the 2nd declension. However, that assumes that it works like a -um form, not as a -us form does. And it really seems to do neither. If it were a -us form (again, as a 2nd declension nominative), then its vocative would have to be *vire; but it's really only virus. You also expect an accusative form *viros, but that too is missing; it's still just virus in the accusative. And if it were a -um form, then its vocative would have to be *virum. But it's not--here again, it's only virus. (Vocative examples of virus are not particularly common. Apparently the Romans seldom addressed their slime in a personal fashion. :-)

So what we have here is something of a mixed or invariant declension. Trying to find a plural for something that didn't take a plural (possibly because it was not a count but a mass noun), or at least, one for which no plural is classically attested, is a fruitless endeavour. Best to stick with English and use viruses. Journey Into the Fourth Declension Some scholars, includining Gavin Betts, believe that virus pertained not to the second declension, but to the fourth one. Here is an example or two that support[5] [slashdot.org] Betts and dispute the 2nd declension theory. The first is classical, from Ammianus [geocities.com]:

qui ut coluber copia virus exuberans natorum

Just another note: You must not forget that Ammian's native tongue was Greek, not Latin - so it's (very hypothetical!) possible he understood virus as a so called accusativus respectus and copia as adverbial expression. (A more common phenomenon in Greek.) exuberare was combined that way with lucrum and there was a tendency to use non-transitive verbs in a (active) transitive way - like anhelare or spumare in late antiquity's Latin as well. (The pseudo-Ciceronian Rhetorica ad Herennium's fourth book is an outstanding exception with its usage of anhelans et spumans in the passage about the denarratio and the following example IF one dates it to 80 a.Chr.n. ...) But - to make a conclusion - it's not classical at all to use the form viri(i), because there isn't any genitive-singular- or nominative-plural-form (*) viri found in the whole Latin literature up to the first century p.Chr.n. as far as PHI-CD-Rom can tell :-)

Here's what other sources have to say about this matter:

alt.usage.english FAQ [ccp14.ac.uk] Not all Latin words ending in -us had plurals in -i. Apparatus, cantus, coitus, hiatus, impetus, Jesus, nexus, plexus, prospectus, and status were 4th declension in Latin, and had plurals in -us with a long `u'. Corpus, genus, and opus were 3rd declension, with plurals corpora, genera, and opera. Virus is not attested in the plural in Latin, and is of a rare form (2nd declension neuter in -us) that makes it debatable what the Latin plural would have been; the only plural in English is viruses. Omnibus and rebus were not nominative nouns in Latin. Ignoramus was not a noun in Latin.

[...] classical plurals [...] [ilhawaii.net] What is the plural of virus? This neuter in Latin lacked a plural; it would presumably [disputable -tchrist ] have been virora like corpora, the plural of neuter corpus. (Like corpora, virora would be stressed on its initial syllable. As indicated earlier, *corpi would be as outlandish--as far beyond the pale--as *rhinoceri and *octopi.)

Latin had several declensions containing neuter, feminine, and masculine words ending in -us; the plurals are different in each one. Incidentally, the singular of mores (pronounced `moh-rehs') is mos, with the same change of `s' to `r' between vowels heard in corpus : corpora and in genus : genera.

Many Greek nouns retain their original gender: as, arctus (F.), the Polar Bear; methodus (F.), method.

/* Begin Excerpt */

Numerous Latin words have been taken over into the modern scientific vocabulary, most without difficulty. The Latin word virus, however, presents a minor but interesting problem, if one wishes to express a phrase such as Index of Viruses in its Latin form. By analogy with other nouns, one would expect the normal Latin equivalent to be Index Virorum. The difficulty stems from the fact that the Latin noun virus is defective, i.e. does not have a full set of case--forms, singular and plural. The Roman grammarian Priscian (fl. 500 A.D.) states that some claim the word is indeclinable (i.e., has only one form for all the cases in the singular); others, apparently more accurately, that it is declined in the singular according to the second declension neuter and cite two passages from the poet Lucretius in substantiation. All of the ancient grammarians are in agreement, however, that the word is used in the singular only, which indeed appears to be true, for no plural forms are attested in extant Latin works.

In antiquity the word virus had not yet acquired, of course, its current scientific meaning; rather it denoted something like toxicity, venom, a poisonous, deleterious, or unpleasant agent or principle, or poison in the abstract or general sense. (The first meaning given for this word, a slimy liquid, slime, in the most widely used Latin-English dictionaries is inaccurate; the error has been corrected in the more recent Oxford Latin Dictionary.) Nouns denoting entities that are countable pluralize (book, books); nouns denoting noncountable entities do not (except under special circumstances) pluralize (air, mood, valor). The term virus in antiquity appears to have belonged to the latter category, hence the nonexistence of plural forms.

When the word was taken over into modern languages and acquired its current scientific meaning, it changed categories and denoted a countable entity. The modern languages which have adopted the word each pluralize it in their own fashion (e.g., Eng. viruses, Germ. Viren; French and Italian do not distinguish in form between singular and plural, virus). But what to do in neo-Latin, which normally is subject to the rules and constraints of classical Latin?

W. T. Steam in his manual on botanical Latin (Botanical Latin, Newton Abbey, 2nd ed., 1973) gives what would be the normal plural forms of such a second declension neuter noun: nominative vira, genitive virorum, without, however, indicating his authority for those forms. It may be observed that in Latin as in other languages when the plural of noncountable nouns does occur, it generally denotes various kinds of the entity (e.g., wine, honey, oil). Steam may have applied this principle to virus in order to meet the requirements of modern scientific terminology. If Latin had continued to be the common international language of scholars and scientists at the time that viruses were first identified, it appears likely that it would have generated the forms adduced by Steam.

On the Presence of a Plural of the Latin Noun "Virus"

With interest I read the contribution `On the Absence of a Plural of the Latin Noun ``Virus''' in the June 1999 ASM News, p. 388, by Robert J. Smutny. However, according to my Latin grammar, one of the very few books of my gymnasium (high school) days that is still up to date, the plural of the noun virus in Latin is, like the plural nowadays used for virus in Romance languages (e.g., Italian and French), also virus. The Latin noun virus does not belong to the second declension group but, like the noun fructus, meaning fruit or piece of fruit, belongs to a group of Latin words that is declined according to the fourth declension. Hence, two pieces of fruit is in Latin duo fructus and two viruses would be duo virus. According to the fourth declension the plural genitive of virus in Latin is viruum and therefore an Index of Viruses is in Latin an Index Viruum. Virorum is the plural genitive of the Latin noun vir (second declension) meaning man or husband. Consequently an Index Virorum would indicate a list of husbands or men.

Moreover, because the noun virus belongs to the fourth declension group the study of viruses should have been called virulogy and people practicing that science virulogists. My former professor in virology at veterinary school consequently called himself a virulogist and he lectured virulogy. I am afraid that these words have become extinct since he died.

It is important to realize that Latin and Greek derived expressions in biomedical English have been coined by scientists for convenience and not by scholars based on classical grammar. The old Romans might have said to these scientists modulating their language: ``Ut desint vires, tamen est laudanda voluntas,'' which means freely translated: ``Despite your lack of knowledge, still appreciated.''

Etymology: a. L. virus slimy liquid, poison, offensive odour or taste. Hence also Fr., Sp., Pg. virus.

1 Venom, such as is emitted by a poisonous animal. Also fig.

2 Path. a A morbid principle or poisonous substance produced in the body as the result of some disease, esp. one capable of being introduced into other persons or animals by inoculations or otherwise and of developing the same disease in them. Now superseded by the next sense.

b Pl. viruses. An infectious organism that is usu. submicroscopic, can multiply only inside certain living host cells (in many cases causing disease) and is now understood to be a non-cellular structure lacking any intrinsic metabolism and usually comprising a DNA or RNA core inside a protein coat (see also quot. 1977). [ Formerly referred to as filterable viruses, their first distinguishing characteristic being the ability to pass through filters that retained bacteria. ]

The simple answer is that there wasn't one. The longer answer follows.

Writers who, searching for a fancy plural to virus, incorrectly write *viri are doubtless blindly applying an overreaching -us => -i rule. This mis-inflects many words. For example, status and hiatus only change the length of the final vowel; genus goes to genera; corpus goes to corpora. Others are even worse if this rule is mis-applied, like syllabus, caucus, octopus, mandamus, and rebus.

Anyway, Latin already had a word viri, but it was the nominative plural not of virus (slime, poison, or venom), but of vir (man), which as it turns out is also a 2nd declension noun. I do not believe that writers of English who write viri are intentionally speaking of men. And although there actually is a viri form for virus, it's the genitive singular[1] [slashdot.org], not the nominative plural. And we certainly don't grab for genitive singulars for the plurals when we've started out with a nominative. Such hanky panky would certainly get you talked about, and probably your hand slapped as well.

This apparently invariant use of virus as a genitive singular may also imply that it's 4th declension, as some scholars [slashdot.org] believe.

Those confused souls who write *virii are tacitly positing the existence of the non-word *virius, and declining it as though it were like filius. It's true that l/r are both linguals that sometimes get interchanged, and that f/v are just a change in voicing[2] [slashdot.org], but that's just reaching. *Virii is still completely silly, so don't do that; otherwise, everyone will know you're just a blathering script kiddie.

The crucial problem here is that, classically speaking, there appears to be no recorded use of virus in the plural. It was a 2nd declension noun ending in -us, which is rather common, but it was also a neuter, which is rather rare. I could only come up with three such 2nd declension neuters: virus [tufts.edu] (some poison), pelagus [tufts.edu] (the sea, usually poetically), and vulgus [tufts.edu] (the crowd). None appear to admit plurals. Perhaps this is because they are mass nouns, not count nouns. [3] [slashdot.org]

One citation below wonders whether these -us 2nd declension neuters might have inflected -us => -ora, the way the 3rd declension's neuter plurals for tempus and corpus do. There's really not any support for that notion--that I could find at least. If so, that would end up producing *virora. Most other citations think that these plurals just never happened at all, or that if they did, they didn't jump declensions. Perhaps they were invariant as they oddly are for the vocative and accusative cases. In any event, *virora does not fit comfortably in the mouth of an English speaker, which is a good reason to avoid it.[4] [slashdot.org]

Another theory holds that virus, if it was a 2nd declension neuter, must go to *vira in the plural as do its -um neuter brethren in the 2nd declension. However, that assumes that it works like a -um form, not as a -us form does. And it really seems to do neither. If it were a -us form (again, as a 2nd declension nominative), then its vocative would have to be *vire; but it's really only virus. You also expect an accusative form *viros, but that too is missing; it's still just virus in the accusative. And if it were a -um form, then its vocative would have to be *virum. But it's not--here again, it's only virus. (Vocative examples of virus are not particularly common. Apparently the Romans seldom addressed their slime in a personal fashion. :-)

This apparently invariant use of virus as a genitive singular may also imply that it's 4th declension, as some scholars believe.

Those confused souls who write *virii are tacitly positing the existence of the non-word *virius, and declining it as though it were like filius. It's true that l/r are both linguals that sometimes get interchanged, and that f/v are just a change in voicing[2], but that's just reaching. *Virii is still completely silly, so don't do that; otherwise, everyone will know you're just a blathering script kiddie.

The crucial problem here is that, classically speaking, there appears to be no recorded use of virus in the plural. It was a 2nd declension noun ending in -us, which is rather common, but it was also a neuter, which is rather rare. I could only come up with three such 2nd declension neuters: virus (some poison), pelagus (the sea, usually poetically), and vulgus (the crowd). None appear to admit plurals. Perhaps this is because they are mass nouns, not count nouns. [3]

One citation below wonders whether these -us 2nd declension neuters might have inflected -us => -ora, the way the 3rd declension's neuter plurals for tempus and corpus do. There's really not any support for that notion--that I could find at least. If so, that would end up producing *virora. Most other citations think that these plurals just never happened at all, or that if they did, they didn't jump declensions. Perhaps they were invariant as they oddly are for the vocative and accusative cases. In any event, *virora does not fit comfortably in the mouth of an English speaker, which is a good reason to avoid it.[4]

Another theory holds that virus, if it was a 2nd declension neuter, must go to *vira in the plural as do its -um neuter brethren in the 2nd declension. However, that assumes that it works like a -um form, not as a -us form does. And it really seems to do neither. If it were a -us form (again, as a 2nd declension nominative), then its vocative would have to be *vire; but it's really only virus. You also expect an accusative form *viros, but that too is missing; it's still just virus in the accusative. And if it were a -um form, then its vocative would have to be *virum. But it's not--here again, it's only virus. (Vocative examples of virus are not particularly common. Apparently the Romans seldom addressed their slime in a personal fashion. :-)

So what we have here is something of a mixed or invariant declension. Trying to find a plural for something that didn't take a plural (possibly because it was not a count but a mass noun), or at least, one for which no plural is classically attested, is a fruitless endeavour. Best to stick with English and use viruses. Journey Into the Fourth Declension Some scholars, includining Gavin Betts, believe that virus pertained not to the second declension, but to the fourth one. Here is an example or two that support[5] Betts and dispute the 2nd declension theory. The first is classical, from Ammianus:

qui ut coluber copia virus exuberans natorum

Just another note: You must not forget that Ammian's native tongue was Greek, not Latin - so it's (very hypothetical!) possible he understood virus as a so called accusativus respectus and copia as adverbial expression. (A more common phenomenon in Greek.) exuberare was combined that way with lucrum and there was a tendency to use non-transitive verbs in a (active) transitive way - like anhelare or spumare in late antiquity's Latin as well. (The pseudo-Ciceronian Rhetorica ad Herennium's fourth book is an outstanding exception with its usage of anhelans et spumans in the passage about the denarratio and the following example IF one dates it to 80 a.Chr.n. ...) But - to make a conclusion - it's not classical at all to use the form viri(i), because there isn't any genitive-singular- or nominative-plural-form (*) viri found in the whole Latin literature up to the first century p.Chr.n. as far as PHI-CD-Rom can tell :-)

Here's what other sources have to say about this matter:

alt.usage.english FAQ Not all Latin words ending in -us had plurals in -i. Apparatus, cantus, coitus, hiatus, impetus, Jesus, nexus, plexus, prospectus, and status were 4th declension in Latin, and had plurals in -us with a long `u'. Corpus, genus, and opus were 3rd declension, with plurals corpora, genera, and opera. Virus is not attested in the plural in Latin, and is of a rare form (2nd declension neuter in -us) that makes it debatable what the Latin plural would have been; the only plural in English is viruses. Omnibus and rebus were not nominative nouns in Latin. Ignoramus was not a noun in Latin.

[...] classical plurals [...] What is the plural of virus? This neuter in Latin lacked a plural; it would presumably [disputable -tchrist ] have been virora like corpora, the plural of neuter corpus. (Like corpora, virora would be stressed on its initial syllable. As indicated earlier, *corpi would be as outlandish--as far beyond the pale--as *rhinoceri and *octopi.)

Latin had several declensions containing neuter, feminine, and masculine words ending in -us; the plurals are different in each one. Incidentally, the singular of mores (pronounced `moh-rehs') is mos, with the same change of `s' to `r' between vowels heard in corpus : corpora and in genus : genera.

Allen and Greenough The authors at the cited reference point out the follwoing:

Many Greek nouns retain their original gender: as, arctus (F.), the Polar Bear; methodus (F.), method.

a. The following in -us are Neuter; their accusative (as with all neuters) is the same as the nominative: pelagus, sea; virus, poison; vulgus (rarely M.), the crowd. They are not found in the plural, except pelagus, which has a rare nominative and accusative plural pelage.

NOTE.--The nominative plural neuter cete, sea monsters, occurs; the nominative singular cetus occurs in Vitruvius.

/* Begin Excerpt */

Numerous Latin words have been taken over into the modern scientific vocabulary, most without difficulty. The Latin word virus, however, presents a minor but interesting problem, if one wishes to express a phrase such as Index of Viruses in its Latin form. By analogy with other nouns, one would expect the normal Latin equivalent to be Index Virorum. The difficulty stems from the fact that the Latin noun virus is defective, i.e. does not have a full set of case--forms, singular and plural. The Roman grammarian Priscian (fl. 500 A.D.) states that some claim the word is indeclinable (i.e., has only one form for all the cases in the singular); others, apparently more accurately, that it is declined in the singular according to the second declension neuter and cite two passages from the poet Lucretius in substantiation. All of the ancient grammarians are in agreement, however, that the word is used in the singular only, which indeed appears to be true, for no plural forms are attested in extant Latin works.

In antiquity the word virus had not yet acquired, of course, its current scientific meaning; rather it denoted something like toxicity, venom, a poisonous, deleterious, or unpleasant agent or principle, or poison in the abstract or general sense. (The first meaning given for this word, a slimy liquid, slime, in the most widely used Latin-English dictionaries is inaccurate; the error has been corrected in the more recent Oxford Latin Dictionary.) Nouns denoting entities that are countable pluralize (book, books); nouns denoting noncountable entities do not (except under special circumstances) pluralize (air, mood, valor). The term virus in antiquity appears to have belonged to the latter category, hence the nonexistence of plural forms.

When the word was taken over into modern languages and acquired its current scientific meaning, it changed categories and denoted a countable entity. The modern languages which have adopted the word each pluralize it in their own fashion (e.g., Eng. viruses, Germ. Viren; French and Italian do not distinguish in form between singular and plural, virus). But what to do in neo-Latin, which normally is subject to the rules and constraints of classical Latin?

W. T. Steam in his manual on botanical Latin (Botanical Latin, Newton Abbey, 2nd ed., 1973) gives what would be the normal plural forms of such a second declension neuter noun: nominative vira, genitive virorum, without, however, indicating his authority for those forms. It may be observed that in Latin as in other languages when the plural of noncountable nouns does occur, it generally denotes various kinds of the entity (e.g., wine, honey, oil). Steam may have applied this principle to virus in order to meet the requirements of modern scientific terminology. If Latin had continued to be the common international language of scholars and scientists at the time that viruses were first identified, it appears likely that it would have generated the forms adduced by Steam.

On the Presence of a Plural of the Latin Noun "Virus"

With interest I read the contribution `On the Absence of a Plural of the Latin Noun ``Virus''' in the June 1999 ASM News, p. 388, by Robert J. Smutny. However, according to my Latin grammar, one of the very few books of my gymnasium (high school) days that is still up to date, the plural of the noun virus in Latin is, like the plural nowadays used for virus in Romance languages (e.g., Italian and French), also virus. The Latin noun virus does not belong to the second declension group but, like the noun fructus, meaning fruit or piece of fruit, belongs to a group of Latin words that is declined according to the fourth declension. Hence, two pieces of fruit is in Latin duo fructus and two viruses would be duo virus. According to the fourth declension the plural genitive of virus in Latin is viruum and therefore an Index of Viruses is in Latin an Index Viruum. Virorum is the plural genitive of the Latin noun vir (second declension) meaning man or husband. Consequently an Index Virorum would indicate a list of husbands or men.

Moreover, because the noun virus belongs to the fourth declension group the study of viruses should have been called virulogy and people practicing that science virulogists. My former professor in virology at veterinary school consequently called himself a virulogist and he lectured virulogy. I am afraid that these words have become extinct since he died.

It is important to realize that Latin and Greek derived expressions in biomedical English have been coined by scientists for convenience and not by scholars based on classical grammar. The old Romans might have said to these scientists modulating their language: ``Ut desint vires, tamen est laudanda voluntas,'' which means freely translated: ``Despite your lack of knowledge, still appreciated.''

Etymology: a. L. virus slimy liquid, poison, offensive odour or taste. Hence also Fr., Sp., Pg. virus.

1 Venom, such as is emitted by a poisonous animal. Also fig.

2 Path. a A morbid principle or poisonous substance produced in the body as the result of some disease, esp. one capable of being introduced into other persons or animals by inoculations or otherwise and of developing the same disease in them. Now superseded by the next sense.

b Pl. viruses. An infectious organism that is usu. submicroscopic, can multiply only inside certain living host cells (in many cases causing disease) and is now understood to be a non-cellular structure lacking any intrinsic metabolism and usually comprising a DNA or RNA core inside a protein coat (see also quot. 1977). [ Formerly referred to as filterable viruses, their first distinguishing characteristic being the ability to pass through filters that retained bacteria. ]

The simple answer is that there wasn't one. The longer answer follows.

Writers who, searching for a fancy plural to virus, incorrectly write *viri are doubtless blindly applying an overreaching -us => -i rule. This mis-inflects many words. For example, status and hiatus only change the length of the final vowel; genus goes to genera; corpus goes to corpora. Others are even worse if this rule is mis-applied, like syllabus, caucus, octopus, mandamus, and rebus.

Anyway, Latin already had a word viri, but it was the nominative plural not of virus (slime, poison, or venom), but of vir (man), which as it turns out is also a 2nd declension noun. I do not believe that writers of English who write viri are intentionally speaking of men. And although there actually is a viri form for virus, it's the genitive singular[1], not the nominative plural. And we certainly don't grab for genitive singulars for the plurals when we've started out with a nominative. Such hanky panky would certainly get you talked about, and probably your hand slapped as well.

And we certainly don't grab for genitive singulars for the plurals when we've started out with a nominative. Such hanky panky would certainly get you talked about, and probably your hand slapped as well.

This apparently invariant use of virus as a genitive singular may also imply that it's 4th declension, as some scholars believe.

Those confused souls who write *virii are tacitly positing the existence of the non-word *virius, and declining it as though it were like filius. It's true that l/r are both linguals that sometimes get interchanged, and that f/v are just a change in voicing[2], but that's just reaching. *Virii is still completely silly, so don't do that; otherwise, everyone will know you're just a blathering script kiddie.

The crucial problem here is that, classically speaking, there appears to be no recorded use of virus in the plural. It was a 2nd declension noun ending in -us, which is rather common, but it was also a neuter, which is rather rare. I could only come up with three such 2nd declension neuters: virus (some poison), pelagus (the sea, usually poetically), and vulgus (the crowd). None appear to admit plurals. Perhaps this is because they are mass nouns, not count nouns. [3]

One citation below wonders whether these -us 2nd declension neuters might have inflected -us => -ora, the way the 3rd declension's neuter plurals for tempus and corpus do. There's really not any support for that notion--that I could find at least. If so, that would end up producing *virora. Most other citations think that these plurals just never happened at all, or that if they did, they didn't jump declensions. Perhaps they were invariant as they oddly are for the vocative and accusative cases. In any event, *virora does not fit comfortably in the mouth of an English speaker, which is a good reason to avoid it.[4]

Another theory holds that virus, if it was a 2nd declension neuter, must go to *vira in the plural as do its -um neuter brethren in the 2nd declension. However, that assumes that it works like a -um form, not as a -us form does. And it really seems to do neither. If it were a -us form (again, as a 2nd declension nominative), then its vocative would have to be *vire; but it's really only virus. You also expect an accusative form *viros, but that too is missing; it's still just virus in the accusative. And if it were a -um form, then its vocative would have to be *virum. But it's not--here again, it's only virus. (Vocative examples of virus are not particularly common. Apparently the Romans seldom addressed their slime in a personal fashion. :-)

So what we have here is something of a mixed or invariant declension. Trying to find a plural for something that didn't take a plural (possibly because it was not a count but a mass noun), or at least, one for which no plural is classically attested, is a fruitless endeavour. Best to stick with English and use viruses. Journey Into the Fourth Declension Some scholars, includining Gavin Betts, believe that virus pertained not to the second declension, but to the fourth one. Here is an example or two that support[5] Betts and dispute the 2nd declension theory. The first is classical, from Ammianus:

qui ut coluber copia virus exuberans natorum

Just another note: You must not forget that Ammian's native tongue was Greek, not Latin - so it's (very hypothetical!) possible he understood virus as a so called accusativus respectus and copia as adverbial expression. (A more common phenomenon in Greek.) exuberare was combined that way with lucrum and there was a tendency to use non-transitive verbs in a (active) transitive way - like anhelare or spumare in late antiquity's Latin as well. (The pseudo-Ciceronian Rhetorica ad Herennium's fourth book is an outstanding exception with its usage of anhelans et spumans in the passage about the denarratio and the following example IF one dates it to 80 a.Chr.n. ...) But - to make a conclusion - it's not classical at all to use the form viri(i), because there isn't any genitive-singular- or nominative-plural-form (*) viri found in the whole Latin literature up to the first century p.Chr.n. as far as PHI-CD-Rom can tell :-)

Here's what other sources have to say about this matter:

alt.usage.english FAQ Not all Latin words ending in -us had plurals in -i. Apparatus, cantus, coitus, hiatus, impetus, Jesus, nexus, plexus, prospectus, and status were 4th declension in Latin, and had plurals in -us with a long `u'. Corpus, genus, and opus were 3rd declension, with plurals corpora, genera, and opera. Virus is not attested in the plural in Latin, and is of a rare form (2nd declension neuter in -us) that makes it debatable what the Latin plural would have been; the only plural in English is viruses. Omnibus and rebus were not nominative nouns in Latin. Ignoramus was not a noun in Latin.

[...] classical plurals [...] What is the plural of virus? This neuter in Latin lacked a plural; it would presumably [disputable -tchrist ] have been virora like corpora, the plural of neuter corpus. (Like corpora, virora would be stressed on its initial syllable. As indicated earlier, *corpi would be as outlandish--as far beyond the pale--as *rhinoceri and *octopi.)

Latin had several declensions containing neuter, feminine, and masculine words ending in -us; the plurals are different in each one. Incidentally, the singular of mores (pronounced `moh-rehs') is mos, with the same change of `s' to `r' between vowels heard in corpus : corpora and in genus : genera.

Allen and Greenough The authors at the cited reference point out the follwoing:

Many Greek nouns retain their original gender: as, arctus (F.), the Polar Bear; methodus (F.), method.

a. The following in -us are Neuter; their accusative (as with all neuters) is the same as the nominative: pelagus, sea; virus, poison; vulgus (rarely M.), the crowd. They are not found in the plural, except pelagus, which has a rare nominative and accusative plural pelage.

NOTE.--The nominative plural neuter cete, sea monsters, occurs; the nominative singular cetus occurs in Vitruvius.

/* Begin Excerpt */

Numerous Latin words have been taken over into the modern scientific vocabulary, most without difficulty. The Latin word virus, however, presents a minor but interesting problem, if one wishes to express a phrase such as Index of Viruses in its Latin form. By analogy with other nouns, one would expect the normal Latin equivalent to be Index Virorum. The difficulty stems from the fact that the Latin noun virus is defective, i.e. does not have a full set of case--forms, singular and plural. The Roman grammarian Priscian (fl. 500 A.D.) states that some claim the word is indeclinable (i.e., has only one form for all the cases in the singular); others, apparently more accurately, that it is declined in the singular according to the second declension neuter and cite two passages from the poet Lucretius in substantiation. All of the ancient grammarians are in agreement, however, that the word is used in the singular only, which indeed appears to be true, for no plural forms are attested in extant Latin works.

In antiquity the word virus had not yet acquired, of course, its current scientific meaning; rather it denoted something like toxicity, venom, a poisonous, deleterious, or unpleasant agent or principle, or poison in the abstract or general sense. (The first meaning given for this word, a slimy liquid, slime, in the most widely used Latin-English dictionaries is inaccurate; the error has been corrected in the more recent Oxford Latin Dictionary.) Nouns denoting entities that are countable pluralize (book, books); nouns denoting noncountable entities do not (except under special circumstances) pluralize (air, mood, valor). The term virus in antiquity appears to have belonged to the latter category, hence the nonexistence of plural forms.

When the word was taken over into modern languages and acquired its current scientific meaning, it changed categories and denoted a countable entity. The modern languages which have adopted the word each pluralize it in their own fashion (e.g., Eng. viruses, Germ. Viren; French and Italian do not distinguish in form between singular and plural, virus). But what to do in neo-Latin, which normally is subject to the rules and constraints of classical Latin?

W. T. Steam in his manual on botanical Latin (Botanical Latin, Newton Abbey, 2nd ed., 1973) gives what would be the normal plural forms of such a second declension neuter noun: nominative vira, genitive virorum, without, however, indicating his authority for those forms. It may be observed that in Latin as in other languages when the plural of noncountable nouns does occur, it generally denotes various kinds of the entity (e.g., wine, honey, oil). Steam may have applied this principle to virus in order to meet the requirements of modern scientific terminology. If Latin had continued to be the common international language of scholars and scientists at the time that viruses were first identified, it appears likely that it would have generated the forms adduced by Steam.

On the Presence of a Plural of the Latin Noun "Virus"

With interest I read the contribution `On the Absence of a Plural of the Latin Noun ``Virus''' in the June 1999 ASM News, p. 388, by Robert J. Smutny. However, according to my Latin grammar, one of the very few books of my gymnasium (high school) days that is still up to date, the plural of the noun virus in Latin is, like the plural nowadays used for virus in Romance languages (e.g., Italian and French), also virus. The Latin noun virus does not belong to the second declension group but, like the noun fructus, meaning fruit or piece of fruit, belongs to a group of Latin words that is declined according to the fourth declension. Hence, two pieces of fruit is in Latin duo fructus and two viruses would be duo virus. According to the fourth declension the plural genitive of virus in Latin is viruum and therefore an Index of Viruses is in Latin an Index Viruum. Virorum is the plural genitive of the Latin noun vir (second declension) meaning man or husband. Consequently an Index Virorum would indicate a list of husbands or men.

Moreover, because the noun virus belongs to the fourth declension group the study of viruses should have been called virulogy and people practicing that science virulogists. My former professor in virology at veterinary school consequently called himself a virulogist and he lectured virulogy. I am afraid that these words have become extinct since he died.

It is important to realize that Latin and Greek derived expressions in biomedical English have been coined by scientists for convenience and not by scholars based on classical grammar. The old Romans might have said to these scientists modulating their language: ``Ut desint vires, tamen est laudanda voluntas,'' which means freely translated: ``Despite your lack of knowledge, still appreciated.''

Etymology: a. L. virus slimy liquid, poison, offensive odour or taste. Hence also Fr., Sp., Pg. virus.

1 Venom, such as is emitted by a poisonous animal. Also fig.

2 Path. a A morbid principle or poisonous substance produced in the body as the result of some disease, esp. one capable of being introduced into other persons or animals by inoculations or otherwise and of developing the same disease in them. Now superseded by the next sense.

b Pl. viruses. An infectious organism that is usu. submicroscopic, can multiply only inside certain living host cells (in many cases causing disease) and is now understood to be a non-cellular structure lacking any intrinsic metabolism and usually comprising a DNA or RNA core inside a protein coat (see also quot. 1977). [ Formerly referred to as filterable viruses, their first distinguishing characteristic being the ability to pass through filters that retained bacteria. ]

The simple answer is that there wasn't one. The longer answer follows.

Writers who, searching for a fancy plural to virus, incorrectly write *viri are doubtless blindly applying an overreaching -us => -i rule. This mis-inflects many words. For example, status and hiatus only change the length of the final vowel; genus goes to genera; corpus goes to corpora. Others are even worse if this rule is mis-applied, like syllabus, caucus, octopus, mandamus, and rebus.

Anyway, Latin already had a word viri, but it was the nominative plural not of virus (slime, poison, or venom), but of vir (man), which as it turns out is also a 2nd declension noun. I do not believe that writers of English who write viri are intentionally speaking of men. And although there actually is a viri form for virus, it's the genitive singular[1], not the nominative plural.

And although there actually is a viri form for virus, it's the genitive singular[1], not the nominative plural. And we certainly don't grab for genitive singulars for the plurals when we've started out with a nominative. Such hanky panky would certainly get you talked about, and probably your hand slapped as well.

This apparently invariant use of virus as a genitive singular may also imply that it's 4th declension, as some scholars believe.

Those confused souls who write *virii are tacitly positing the existence of the non-word *virius, and declining it as though it were like filius. It's true that l/r are both linguals that sometimes get interchanged, and that f/v are just a change in voicing[2], but that's just reaching. *Virii is still completely silly, so don't do that; otherwise, everyone will know you're just a blathering script kiddie.

The crucial problem here is that, classically speaking, there appears to be no recorded use of virus in the plural. It was a 2nd declension noun ending in -us, which is rather common, but it was also a neuter, which is rather rare. I could only come up with three such 2nd declension neuters: virus (some poison), pelagus (the sea, usually poetically), and vulgus (the crowd). None appear to admit plurals. Perhaps this is because they are mass nouns, not count nouns. [3]

One citation below wonders whether these -us 2nd declension neuters might have inflected -us => -ora, the way the 3rd declension's neuter plurals for tempus and corpus do. There's really not any support for that notion--that I could find at least. If so, that would end up producing *virora. Most other citations think that these plurals just never happened at all, or that if they did, they didn't jump declensions. Perhaps they were invariant as they oddly are for the vocative and accusative cases. In any event, *virora does not fit comfortably in the mouth of an English speaker, which is a good reason to avoid it.[4]

Another theory holds that virus, if it was a 2nd declension neuter, must go to *vira in the plural as do its -um neuter brethren in the 2nd declension. However, that assumes that it works like a -um form, not as a -us form does. And it really seems to do neither. If it were a -us form (again, as a 2nd declension nominative), then its vocative would have to be *vire; but it's really only virus. You also expect an accusative form *viros, but that too is missing; it's still just virus in the accusative. And if it were a -um form, then its vocative would have to be *virum. But it's not--here again, it's only virus. (Vocative examples of virus are not particularly common. Apparently the Romans seldom addressed their slime in a personal fashion. :-)

So what we have here is something of a mixed or invariant declension. Trying to find a plural for something that didn't take a plural (possibly because it was not a count but a mass noun), or at least, one for which no plural is classically attested, is a fruitless endeavour. Best to stick with English and use viruses. Journey Into the Fourth Declension Some scholars, includining Gavin Betts, believe that virus pertained not to the second declension, but to the fourth one. Here is an example or two that support[5] Betts and dispute the 2nd declension theory. The first is classical, from Ammianus:

qui ut coluber copia virus exuberans natorum

Just another note: You must not forget that Ammian's native tongue was Greek, not Latin - so it's (very hypothetical!) possible he understood virus as a so called accusativus respectus and copia as adverbial expression. (A more common phenomenon in Greek.) exuberare was combined that way with lucrum and there was a tendency to use non-transitive verbs in a (active) transitive way - like anhelare or spumare in late antiquity's Latin as well. (The pseudo-Ciceronian Rhetorica ad Herennium's fourth book is an outstanding exception with its usage of anhelans et spumans in the passage about the denarratio and the following example IF one dates it to 80 a.Chr.n. ...) But - to make a conclusion - it's not classical at all to use the form viri(i), because there isn't any genitive-singular- or nominative-plural-form (*) viri found in the whole Latin literature up to the first century p.Chr.n. as far as PHI-CD-Rom can tell :-)

Here's what other sources have to say about this matter:

alt.usage.english FAQ Not all Latin words ending in -us had plurals in -i. Apparatus, cantus, coitus, hiatus, impetus, Jesus, nexus, plexus, prospectus, and status were 4th declension in Latin, and had plurals in -us with a long `u'. Corpus, genus, and opus were 3rd declension, with plurals corpora, genera, and opera. Virus is not attested in the plural in Latin, and is of a rare form (2nd declension neuter in -us) that makes it debatable what the Latin plural would have been; the only plural in English is viruses. Omnibus and rebus were not nominative nouns in Latin. Ignoramus was not a noun in Latin.

[...] classical plurals [...] What is the plural of virus? This neuter in Latin lacked a plural; it would presumably [disputable -tchrist ] have been virora like corpora, the plural of neuter corpus. (Like corpora, virora would be stressed on its initial syllable. As indicated earlier, *corpi would be as outlandish--as far beyond the pale--as *rhinoceri and *octopi.)

Latin had several declensions containing neuter, feminine, and masculine words ending in -us; the plurals are different in each one. Incidentally, the singular of mores (pronounced `moh-rehs') is mos, with the same change of `s' to `r' between vowels heard in corpus : corpora and in genus : genera.

Allen and Greenough The authors at the cited reference point out the follwoing:

Many Greek nouns retain their original gender: as, arctus (F.), the Polar Bear; methodus (F.), method.

a. The following in -us are Neuter; their accusative (as with all neuters) is the same as the nominative: pelagus, sea; virus, poison; vulgus (rarely M.), the crowd. They are not found in the plural, except pelagus, which has a rare nominative and accusative plural pelage.

NOTE.--The nominative plural neuter cete, sea monsters, occurs; the nominative singular cetus occurs in Vitruvius.

Numerous Latin words have been taken over into the modern scientific vocabulary, most without difficulty. The Latin word virus, however, presents a minor but interesting problem, if one wishes to express a phrase such as Index of Viruses in its Latin form. By analogy with other nouns, one would expect the normal Latin equivalent to be Index Virorum. The difficulty stems from the fact that the Latin noun virus is defective, i.e. does not have a full set of case--forms, singular and plural. The Roman grammarian Priscian (fl. 500 A.D.) states that some claim the word is indeclinable (i.e., has only one form for all the cases in the singular); others, apparently more accurately, that it is declined in the singular according to the second declension neuter and cite two passages from the poet Lucretius in substantiation. All of the ancient grammarians are in agreement, however, that the word is used in the singular only, which indeed appears to be true, for no plural forms are attested in extant Latin works.

In antiquity the word virus had not yet acquired, of course, its current scientific meaning; rather it denoted something like toxicity, venom, a poisonous, deleterious, or unpleasant agent or principle, or poison in the abstract or general sense. (The first meaning given for this word, a slimy liquid, slime, in the most widely used Latin-English dictionaries is inaccurate; the error has been corrected in the more recent Oxford Latin Dictionary.) Nouns denoting entities that are countable pluralize (book, books); nouns denoting noncountable entities do not (except under special circumstances) pluralize (air, mood, valor). The term virus in antiquity appears to have belonged to the latter category, hence the nonexistence of plural forms.

When the word was taken over into modern languages and acquired its current scientific meaning, it changed categories and denoted a countable entity. The modern languages which have adopted the word each pluralize it in their own fashion (e.g., Eng. viruses, Germ. Viren; French and Italian do not distinguish in form between singular and plural, virus). But what to do in neo-Latin, which normally is subject to the rules and constraints of classical Latin?

W. T. Steam in his manual on botanical Latin (Botanical Latin, Newton Abbey, 2nd ed., 1973) gives what would be the normal plural forms of such a second declension neuter noun: nominative vira, genitive virorum, without, however, indicating his authority for those forms. It may be observed that in Latin as in other languages when the plural of noncountable nouns does occur, it generally denotes various kinds of the entity (e.g., wine, honey, oil). Steam may have applied this principle to virus in order to meet the requirements of modern scientific terminology. If Latin had continued to be the common international language of scholars and scientists at the time that viruses were first identified, it appears likely that it would have generated the forms adduced by Steam.

On the Presence of a Plural of the Latin Noun "Virus"

With interest I read the contribution `On the Absence of a Plural of the Latin Noun ``Virus''' in the June 1999 ASM News, p. 388, by Robert J. Smutny. However, according to my Latin grammar, one of the very few books of my gymnasium (high school) days that is still up to date, the plural of the noun virus in Latin is, like the plural nowadays used for virus in Romance languages (e.g., Italian and French), also virus. The Latin noun virus does not belong to the second declension group but, like the noun fructus, meaning fruit or piece of fruit, belongs to a group of Latin words that is declined according to the fourth declension. Hence, two pieces of fruit is in Latin duo fructus and two viruses would be duo virus. According to the fourth declension the plural genitive of virus in Latin is viruum and therefore an Index of Viruses is in Latin an Index Viruum. Virorum is the plural genitive of the Latin noun vir (second declension) meaning man or husband. Consequently an Index Virorum would indicate a list of husbands or men.

Moreover, because the noun virus belongs to the fourth declension group the study of viruses should have been called virulogy and people practicing that science virulogists. My former professor in virology at veterinary school consequently called himself a virulogist and he lectured virulogy. I am afraid that these words have become extinct since he died.

It is important to realize that Latin and Greek derived expressions in biomedical English have been coined by scientists for convenience and not by scholars based on classical grammar. The old Romans might have said to these scientists modulating their language: ``Ut desint vires, tamen est laudanda voluntas,'' which means freely translated: ``Despite your lack of knowledge, still appreciated.''

Etymology: a. L. virus slimy liquid, poison, offensive odour or taste. Hence also Fr., Sp., Pg. virus.

1 Venom, such as is emitted by a poisonous animal. Also fig.

2 Path. a A morbid principle or poisonous substance produced in the body as the result of some disease, esp. one capable of being introduced into other persons or animals by inoculations or otherwise and of developing the same disease in them. Now superseded by the next sense.

b Pl. viruses. An infectious organism that is usu. submicroscopic, can multiply only inside certain living host cells (in many cases causing disease) and is now understood to be a non-cellular structure lacking any intrinsic metabolism and usually comprising a DNA or RNA core inside a protein coat (see also quot. 1977). [ Formerly referred to as filterable viruses, their first distinguishing characteristic being the ability to pass through filters that retained bacteria. ]

The simple answer is that there wasn't one. The longer answer follows.

Writers who, searching for a fancy plural to virus, incorrectly write *viri are doubtless blindly applying an overreaching -us => -i rule. This mis-inflects many words. For example, status and hiatus only change the length of the final vowel; genus goes to genera; corpus goes to corpora. Others are even worse if this rule is mis-applied, like syllabus, caucus, octopus, mandamus, and rebus.

Anyway, Latin already had a word viri, but it was the nominative plural not of virus (slime, poison, or venom), but of vir (man), which as it turns out is also a 2nd declension noun. I do not believe that writers of English who write viri are intentionally speaking of men. And although there actually is a viri form for virus, it's the genitive singular[1], not the nominative plural.
