Word Origin & History
gaffe
"blunder," 1909, from Fr. gaffe "clumsy remark," originally "boat hook," from O.Fr. gaffe, from O.Prov. gaf, probably from W.Goth. *gafa "hook," from P.Gmc. *gafa. Sense connection is obscure. The gaff was also used to land big fish. Or it may derive from Brit. slang gaff "to cheat, trick" (1893); or gaff "criticism" (1896), from Scot. dial. sense of "loud, rude talk," which ultimately may be from O.E. gaf-spræc "blasphemous or ribald speech."
