A question of plurals

[Sa'ar Chasm]

Virus is a bit odd since it doesn't have a plural in Latin. Broadly (and somewhat inaccurately) speaking, it means gunk, which is...the correct nomenclature escapes me, but I want to say partitive.

Basically, you don't say one gunk, many gunks, you say ewwww, some gunk. Hence, virus as we use it to describe infectious agents has nothing in common with the Latin word.

Also, I come down on the fora side of the debate.
