In 16th-century France "vendre des canards à moitié" was a colorful way of saying "to fool" or "to cheat." The French phrase means, literally, "to half-sell ducks." No one now knows just what was meant by "to half-sell"; the proverb was probably based on some story widely known at the time, but the details have not survived. At any rate, the expression led to the use of "canard," the French word for "duck," with the meaning "a hoax" or "a fabrication." English speakers adopted this "canard" in the mid-1800s. The aeronautical sense of "canard," used from the early days of flying, comes from the stubby duck-like appearance of the aircraft.
