Origin & History of “bone”
Somewhat unusually for a basic body-part term, bone is a strictly Germanic word: it has no relatives in other Indo-European languages. It comes from a presumed Germanic *bainam, which also produced e.g. German bein and Swedish ben. these both mean ‘leg’ as well as ‘bone’, suggesting that the original connotation of *bainam may have been ‘long bone’.
