wart (n.)

Old English weart "wart," from Proto-Germanic *warton- (source also of Old Norse varta, Old Frisian warte, Dutch wrat, Old High German warza, German warze "wart"), perhaps ultimately from the same source as Latin verruca "swelling, wart." Phrase warts and all "without concealment of blemishes" is attested from 1763, supposedly from Oliver Cromwell's instruction to his portrait painter.
