Etymology: Biopolymers is the plural of "biopolymer," a compound built from two Greek-derived pieces: "bio-," from Ancient Greek "bíos" meaning life, and "polymer," which joins "polý," meaning many, with "méros," meaning part. The idea behind the whole word is a chain of many repeated parts, and the "bio-" prefix tells you the chain is made by living things. The "poly-" in the word comes from Greek "polýs," meaning much or many, and it appears in many scientific coinages, such as "polygon" and "polyglot." The "-mer" element is from "méros," meaning part, which gives us a word for a unit that repeats. Put together, "polymer" describes a substance made of many repeated units, and "biopolymer" narrows that to polymers produced by living organisms. The form "biopolymer" is an English compound formed from "bio-" and "polymer," so the word is a modern scientific coinage built from classical roots rather than something ancient Greeks would have used.
