Etymology: The hip socket is named after a vinegar dish. Romans used "acetabulum," from "acetum" (vinegar) plus a diminutive ending meaning a small container, for a small cup, and its round, cup-like shape later led anatomists to apply the name to the socket where the thigh bone fits into the pelvis. English anatomy kept that Latin name, which is why the hip joint's socket still bears it. The adjective "acetabulate" comes from the same Latin noun, with the English "-ate" ending that means "having the form or character of." It is a learned, specialist formation, so it appears mainly in scientific writing. Its exact date of first English use is uncertain, but it belongs to the period when naturalists and anatomists borrowed Latin nouns and turned them into descriptive adjectives.
