vizard n.

c. 1300, viser, "front part of a helmet," from Anglo-French viser, Old French visiere "visor" (13c.), from vis "face, appearance," from Latin visus "a look, vision," from past participle stem of videre "to see" (from PIE root *weid- "to see"). Spelling shifted 15c. Meaning "eyeshade" is recorded from 1925.

also -art, from Old French -ard, -art, from German -hard, -hart "hardy," forming the second element in many personal names, often used as an intensifier, but in Middle High German and Dutch used as a pejorative element in common nouns, and thus passing into Middle English in bastard, coward, blaffard ("one who stammers"), etc. It thus became a living element in English, as in buzzard, drunkard. The German element is from Proto-Germanic *-hart/*-hard "bold, hardy" (from PIE root *kar- "hard").
