Etymology: "Polyzoan" is a scientific coinage, not an ancient word. The first part comes from the Translingual "Polyzoa," the name for the group of colonial animals, built from Greek "polys" meaning "many" and "zōion" meaning "animal." The "-an" ending is the English suffix that turns a group name into a noun for a member of that group, the same pattern that gives us "Lutheran" or "American." The suffix itself has a long pedigree. It descends from a Proto-Italic form "-ānos," which passed into Latin as "-ānus," then into Old French as "-ain," and reached Middle English as "-an." So the ending is ancient even though the Greek-based stem is a modern invention.
