vant-
prefix, representing AF. vant-, aphetic f. avant- avant-: see vant-brace, -guard, -ward. In a number of compounds the t was elided, as vanbrace, -chase, -courier, -guard, etc. Before labials the n by assimilation became m, as in vambrace, vampey, vamplate, vamward; and a further reduction appears in vamure vaumure and vaward. The AF. variant vaunt- is also very fully represented in English forms: see vaunt-chase, -courier, etc.
