[Probably from Dutch boort, tiny waste diamond pieces produced in the gem cutting process, bort , probably from Old French bourt, bastard, from Late Latin burdus, hinny, probably of Celtic origin; akin to Burdō and Burdōnus, ancient Celtic masculine personal names derived from a word for a donkey or mule, animals admired for their robustness.]
