Etymology: "Apterate" is built from "a-", a Greek prefix meaning "not" or "without", and "pterate", from Greek "pteron", "wing". The adjective simply means "wingless" and belongs to the technical vocabulary of zoology and entomology, where it is used of insects and other animals that lack wings, or whose wings have been lost through evolution. It is a coinage from classical roots rather than a word that the ancient Greeks themselves used, as the scientific naming of insect groups took shape in the 18th and 19th centuries. The same Greek root "pteron" sits behind many other scientific terms: "pterodactyl" (wing-finger), "Diptera" (two-winged flies), and "Coleoptera" (sheath-winged beetles, from "koleos", sheath). Each builds on the same stem, so the word fits neatly into a family of wing-related terms used by naturalists.
