Etymology: Toxin itself is a relatively young coinage, built from the Greek word for a bow. Ancient Greek "tóxon" meant "bow" (the archer's weapon), and from it came "toxikón", the poison used to tip arrows, which is the sense that passed into Latin as "toxicum" and eventually into English as "toxin". The link is literal: poisons were smeared on arrowheads, so the name of the weapon became the name of the poison. "Biotoxin" is a modern compound, formed in English by attaching "bio-" to "toxin". The prefix comes from Ancient Greek "bíos", meaning "life", so the word describes a poison produced by a living organism. The plural "biotoxins" simply refers to several such substances.
