Pronunciation

  • IPA: /ˈbɑːs.təd/ (UK); /ˈbæs.tɚd/ (US)[1]

Etymology

It is inherited from Middle English bastard, borrowed from Old French bastard (“acknowledged child of a nobleman by a woman other than his wife”),[2][3] probably from fils de bast (“packsaddle son”),[2][3][4] a child conceived on a makeshift bed (saddles often served as beds while travelling), with the pejorative suffix -ard (see -ard).[2] Others connect it with Medieval Latin bastardus and bastum (“packsaddle”),[4][5] and Merriam-Webster suggests bast meant a barn, perhaps of Germanic origin.[6] The OED online prefers a link with Old Frisian bōst (“morganatic marriage”) or an Old Saxon cognate.[2] Hoad calls it of uncertain origin.[7]

Earliest recorded meaning

An illegitimate child: the early 13th century in Etymonline, about 1300 in Barnhart, 1297 in the OED;[2][3][8] it occurs earlier as an epithet in names (Peter Bastard, 1250).[3]

Semantic evolution

The word was not always a stigma: William the Conqueror was called William the Bastard in state documents.[2] The figurative sense, a thing not pure or genuine, is from the late 14th century,[2] as is the adjective, used of spurious or irregular things and of mongrels and mixed breeds.[2] A sweet Spanish wine was called bastard from 1399, and a kind of cannon from 1549.[8] As a general vulgar term of abuse for a man it is attested from 1830,[2][8] and in informal use it now also means simply a person (lucky bastard) or something very difficult.[9]
