Etymology: The muscle's name is a bit of anatomical scholarship that goes back to ancient Greece. The Greek "gloutos" meant "rump" or "buttock," and anatomists of the early modern period drew on it when they needed a Latin-style name for the large muscles of the backside. Their coinage, "glutaeus" (later spelled "gluteus"), was built on that Greek root and given a Latin ending so that it sat comfortably in the technical vocabulary of medicine. Ancient Greeks and Romans had no word like this one for the muscle itself, since the coinage is a New Latin creation. The result is a term that looks Roman but was largely assembled from Greek material by later scholars who wanted precise names for body parts. The plural form is "glutei," which follows Latin grammar and is still used by anatomists, who typically refer to the three gluteal muscles as the gluteus maximus, medius, and minimus.
