- transitive v. To weed out.

- To pull up by the roots; extirpate utterly.
"averruncate" (from Lat. _averruncare_, to ward off, remove mischief) glided into meaning to "weed the ground," "prune vines," &c., 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.
