Etymology: Bioadhesive is a modern scientific coinage, built from two parts. The first, "bio-", comes from the Ancient Greek "bios", meaning "life", and has been used in English as a combining form for biological matters. The second is "adhesive", which traces back through French "adhésif" to Medieval Latin "adhaesivus", formed from "adhaerere", meaning "to stick to", where "ad-" means "to" and "haerere" means "to stick". So the word literally describes something that sticks to living things. Nothing about the word's history is an ancient story; it was put together in English from these existing parts, so its meaning follows directly from them. The "-ive" ending in "adhesive" comes from Latin "-ivus", a suffix that turns verbs into adjectives describing a quality or tendency.
