Origin of bastard

1250–1300; Middle English < Anglo-French bastard, Medieval Latin bastardus (from 11th century), perhaps < Germanic (Ingvaeonic) *bāst-, presumed variant of *bōst- marriage + Old French -ard -ard, taken as signifying the offspring of a polygynous marriage to a woman of lower status, a pagan tradition not sanctioned by the church; compare Old Frisian bost marriage < Germanic *bandstu-, a noun derivative of Indo-European *bhendh- bind; the traditional explanation of Old French bastard as derivative of fils de bast “child of a packsaddle” is doubtful on chronological and geographical grounds
