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 2 nd declension noun. I do not believe that writers of English who write viri are intentionally speaking of men.o 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.
