1852, "shed for carriages," from French hangar "shed," which is of uncertain origin. Probably from hanghart (14c.), which is perhaps an alteration of Middle Dutch *ham-gaerd "enclosure near a house" [Barnhart, Watkins], from a Proto-Germanic compound *haimgardaz of the elements that make home (n.) and yard (n.1). Or French hanghart might be from Medieval Latin angarium "shed in which horses are shod" [Gamillscheg, Klein]. Sense of "covered shed for airplanes" first recorded in English 1902, from French use in that sense.
