Etymology: "Viral" is a simple formation: the noun "virus" with the adjective-forming suffix "-al" attached. The suffix came into English through Middle English from Latin "-ālis" (via Old French), so the adjective is a straightforward product of that long-established ending rather than a new coinage. The noun it rests on has a surprisingly old pedigree. "Virus" was borrowed into English from Latin, where it meant a poison, slime, or foul liquid, and it traces back further to a reconstructed Proto-Italic root, so its earliest sense was simply something noxious and bodily. Its modern meaning of a disease-causing agent is a much later narrowing of that broad sense. The meaning "spreading quickly like an infection," which is now the more common use of "viral," grew out of the medical sense of the noun and is the reason the adjective is so widely used today in discussions of online content.
