jaw: jaw: [14] Given that it is a fairly important part of the body, our knowledge of the origins of the word for ‘jaw’ is surprisingly sketchy. The Old English terms for ‘jaw’ were céace (modern English cheek) and ceafl (ancestor of modern English jowl), and when jaw first turns up towards the end of the 14th century it is in the form iowe. This strongly suggests a derivation from Old French joe ‘cheek’, but the connection has never been established for certain, and many etymologists consider it more likely that it is related to chew.
jaw (n.): late 14c., "the bones of the mouth," perhaps from Old French joue "cheek," from Gaulish *gauta "cheek," or perhaps a variant of Germanic words related to chew (q.v.); compare also jowl. Replaced Old English ceace, ceafl.
jaw (v.): 1610s, "to catch in the jaws, devour," from jaw (n.). In slang from 1748, "to gossip, to speak" 1810, "to scold." Related: Jawed; jawing. Hence 19c. U.S. slang jawsmith "talkative person" (1887).
