The word averruncate (from Latin averruncare, "to ward off, remove mischief") glided into meaning to weed the ground, prune vines, etc., by a supposed derivation from the Lat. ab, "off", and eruncare, "to weed out", and it was spelt aberuncate to suit this; but the New English Dictionary regards such a derivation as impossible.
