Word History

Etymology

Noun (1)

Middle English croupe, croup, borrowed from Anglo-French croupe (also continental Old French), probably going back to an Old Low Franconian outcome of Germanic *kruppa- "something rounded, bulge" — more at crop entry 1

Note: This etymology is traditional, and phonetically impeccable, though "hindquarters of an animal" is not among the many meanings attested in Germanic for this etymon. Compare group entry 1. See also croupier, crupper.

Noun (2)

noun derivative of croup "to cry hoarsely, croak" (now English regional and Scots), probably of imitative origin

Note: Compare synonymous 16th-century crope, croape, and crow entry 2, croak entry 1.
