Etymology

Origin of anteroom

First recorded in 1755–65; ante- + room

Explanation

An anteroom is a small room or entryway leading to a larger area. You might wait with a tour group in an anteroom before beginning your tour of a castle. You can use the word anteroom as a fancy, old-fashioned way to say "waiting room" or "vestibule." Museum visitors might pause in an anteroom before entering a large gallery, and the butler in an old movie might say, "Please wait in the anteroom." Another word for an anteroom is an antechamber — in fact the French root of both is antichambre, from the Latin anticamera, "room in front."
