• plural noun legs, especially a woman’s legs when considered shapely. A jocular word which now sounds old-fashioned, unsurprisingly in that it originates in the medieval heraldic term for leg, gamb, which in turn comes from Old Northern french dialect gambe (modern French is jambe, Italian is gamba). Gams is sometimes thought to come from ‘gammon’, a word which features in several cockney slang expressions; it does not, but it is distantly related etymologically. It is still heard occasionally throughout the English-speaking world.
