bastard

Origin

From Middle English bastard, bastarde, from Old English bastard (used as an epithet), from Anglo-Norman bastard, Old French bastart (“illegitimate child”), perhaps via Medieval Latin bastardus, of obscure origin. Likely from Frankish *bāst (“marriage, relationship”) + Old French -ard, -art (pejorative suffix denoting a specific quality or condition). Frankish *bāst derives from a North Sea Germanic variety of Proto-Germanic *banstuz (“bond, connection, relationship, marriage with a second woman of lower status”), from Proto-Indo-European *bʰendʰ- (“to tie, bind”) and is related to West Frisian boaste (“marriage, matrimony”), Middle Dutch bast (“lust, heat”), and more distantly to English boose (“cow-stall”). The term probably originally referred to a child from a polygynous marriage of heathen Germanic custom - a practice not sanctioned by the Christian churches. Alternatively, and less likely, Old French bastart may have originated from the Old French term fils de bast (“packsaddle son”), meaning a child conceived on an improvised bed (medieval saddles often doubled as beds while travelling). However chronology makes this difficult, as bastard is attested in Old French from 108...
