Etymology

Origin of bone

First recorded before 900; Middle English bo(o)n, Old English bān; cognate with Old Frisian, Old Saxon bēn, Dutch been “bone,” Old Norse bein “bone, leg,” German Bein “leg”; from Germanic bainam

Explanation

A bone is a single section of a skeleton, made of very hard tissue. Adult human bodies have 206 bones. Your skeleton, which forms the structure of your body, is made up of many different bones, from the tiny bones in your fingers and toes to the largest bone, the femur, or thigh bone. All vertebrates, or animals with spines, have bones — your dog may enjoy gnawing on a bone that originally came from a cow, for example. Informally, when you "bone up on something," you study it.
