"situated in the rear, pertaining to the rear, toward the back," late 14c., probably from an unrecorded Old English adjective from hinder (adv.) "behind, back, afterward," but treated as a comparative of hind (adj.). Related to Old High German hintar, German hinter, Gothic hindar "behind" (prep.).
Middle English had hinderhede, literally "hinder-hood; posterity in time, inferiority in rank;" and hinderling "person fallen from moral or social respectability, wretch," from an Old English term of contempt for a person devoid of honor. Also compare Scottish hinderlins "the buttocks."
