Etymology

Dr John R. Swanton, a linguist who worked with Native American languages, suggested that the name Manchac is derived from ''Imashaka'', which is a Choctaw word meaning "the rear entrance." An early Choctaw language dictionary written by Cyrus Byington defines the word ''im'' as a preposition meaning "place" and ''ashaka'' meaning "the back side or rear"
