Middle English: via Old French from medieval Latin bastardus.

  • Bastard probably derives from medieval Latin bastum ‘packsaddle’ (a horse's saddle which was adapted for supporting loads); the French equivalent was fils de bast or ‘packsaddle son’. The reference was to a loose-living mule driver who used a packsaddle for a pillow and the next morning was off to the next town. See also bat
