hangar (n.) Look up hangar at Dictionary.com
1852, "shed for carriages," from French hangar "shed," which is of uncertain origin. Probably from Middle French 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 the Middle French word 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.
