Word History

Etymology

Noun

Middle English bon, going back to Old English bān, going back to Germanic *baina- (whence also Old Frisian & Old Saxon bēn "bone," Old High German bein "bone, leg," Old Norse bein "bone" and probably beinn "straight"), perhaps going back to Indo-European *b^hoi̯H-n-o-, a derivative of a verbal base *b^hei̯H- "strike, hew," whence, with varying suffixation, Old Irish benaid "(s/he) hews, cuts," robíth "(it) has been struck," Middle Breton benaff "(I) cut," Latin perfinēs (glossed by the Roman grammarian Festus as perfringās "you should break") and probably Old Church Slavic bijǫ, biti "to hit"

Note: Germanic lacks an outcome of Indo-European *h₂ost- "bone" (see osteo-), and it has been theorized that the etymon was replaced by *b^hoi̯H-n-o-, used attributively in the sense "broken off," first with Germanic *ast-a- "branch" and then, with homonymous *ast- "bone" (the expected outcome of *h₂ost-); the meaning "straight" seen in Old Norse beinn may have been an intermediary stage.
