queue (ky) KEY
queued, queu·ing, queues
French, from Old French cue, tail, from Latin cauda, cda
When the British stand in queues (as they have been doing at least since 1837, when this meaning of the word is first recorded in English), they may not realize they form a tail. The French word queue from which the English word is borrowed is a descendant of Latin cda, meaning "tail." French queue appeared in 1748 in English, referring to a plait of hair hanging down the back of the neck. By 1802 wearing a queue was a regulation in the British army, but by the mid-19th century queues had disappeared along with cocked hats. Latin cda is also the source of Italian coda, which was adopted into English as a musical term (like so many other English musical terms that come from Italian). A coda is thus literally the "tail end" of a movement or composition.
