Etymology: The most surprising thing about "bone" is that its original sense was closer to "tusk" than to the skeleton. Old English "bān" covered the bone of a limb and also the tusk of an animal, and the word's cousins across Germanic languages still carry the meaning "leg" as well as "bone": Dutch "been", German "Bein" and Swedish "ben" all do. The skeletal sense is therefore the core, but the physical, body-part focus of the word has stayed constant for well over a thousand years. The Proto-Germanic form ""bainą" is usually linked to ""bainaz", meaning "straight", and that adjective is a striking neighbour. Old Norse "beinn" meant "straight, direct, convenient", and it gave English words like "bain" and "bayne", meaning direct or prompt. The bone and the straight line share an ancestor, though the connection between a bone and straightness is not fully explained.
