[French, long shepherd's mantle, limousine (originally an automobile in which only the rear passengers were fully enclosed under a roof), from feminine of limousin, of Limousin (the automobile perhaps being so called because the roof projected over the driver like the hood of a mantle, or because it was developed by Charles Jeantaud (1843-1906), native of Limousin ).]
