Mow, a heap, and Mow,
to cut down, are quite different words. Mow, a heap, is the Anglo-Saxon mowe; but mow, to cut down, is the Anglo-Saxon máw-an.

There is a third Mow (a wry face), which is the French moue, as Faire la moue à [quel quun], to make faces at someone, and Faire la moue, to pout or sulk. (Dutch, mowe.)
