Origin: 1840–50; < French: literally, duck; Old French quanart drake, orig. cackler, equivalent to can(er) to cackle (of expressive orig.) + -art-art, as in mallart drake; see mallard
before 1850, from Fr. canard "a hoax," lit. "a duck" (from O.Fr. quanart, probably echoic of a duck's quack); said by Littré to be from the phrase vendre un canard à moitié "to half-sell a duck," thus, from some long-forgotten joke, "to cheat."
