Origins

Meanings 1–13, 15–18, 20

Old English bān, which meant "bone" or "tusk" and also "the bone of a limb," became Middle English bon. Behind it is *bainą, Proto-Germanic for "bone," which came from *bainaz ("straight") and may go back to a Proto-Indo-European root meaning "to hit, strike, beat." Dutch been, German Bein ("leg"), and Swedish ben are related.
