throat: [OE] Throat comes from a prehistoric Germanic base *thrut- or *thrūt-. This also produced Old English thrūtian ‘swell’, and a related base *strut- was the source of the now defunct Middle English strouten ‘bulge, swell’ (not to mention Dutch strot ‘throat’), so it has been speculated that the underlying etymological meaning of throat is ‘swollen part’ – an allusion no doubt to the bulge of the Adam’s apple. Throttle [14] is probably a derivative of throat. => throttle
