jaw

From Middle English jowe~joue~jaue, seemingly borrowed from Old French jowe~joue~joe, itself from Vulgar Latin *gauta.

The OED argues that, since Chaucer rhymed jowe with clowe (“claw”), the tonic vowel was not /uː/ and so jowe does not correspond to the French word. (On the other hand, it raises no such objection against the derivation of paw from Old French powe~poue~poe, from *pauta.) It is not clear that Middle English ever borrowed an Old French word in which /ɔw/ had already turned to /u/. If the normal modern English outcome is taken to be the /əʊ/ of clove, escrow, hoe, mow, and soldier (implying a Middle English /ɔw/), then the /ɔː/ of jaw and paw (implying a Middle English /aw/) may be explained as the result of either borrowing from Middle English dialects that merged /ɔw/ into /aw/ or blending with semantically adjacent words like chaule (“jaw”) and clawe (“claw”).

The OED, with reluctance, offers the theory that the original Middle English form could have been an unattested *chowe, from an also-unattested Old English *ċēowe (from Proto-West Germanic *keuwā). /t͡ʃ-/ > /d͡ʒ-/ is not unheard-of; cf. jam, jar, jarm, jitter, and jowl. The OED also note that a variant chaw is in fact documented in English, but only from 1530 onward, some 150 years after the j- forms.
