Word Origin & History
bastardearly 13c., "illegitimate child," from O.Fr. bastard (11c., Mod.Fr. bâtard), "acknowledged child of a nobleman by a woman other than his wife," probably from fils de bast "packsaddle son," meaning a child conceived on an improvised bed (saddles often doubled as beds while traveling), with pejorative
ending -art (see
-ard). Alternative possibly is that the word is from P.Gmc. *banstiz "barn," equally suggestive of low origin. Not always regarded as a stigma; the Conqueror is referred to in state documents as "William the Bastard." Figurative sense is from 1550s; use as a vulgar term of abuse for a man is attested from 1830.
