Syn. -- To Blanch, Whiten. To whiten is the generic term, denoting, to render white; as, to whiten the walls of a room. Usually (though not of necessity) this is supposed to be done by placing some white coloring matter in or upon the surface of the object in question. To blanch is to whiten by the removal of coloring matter; as, to blanch linen. So the cheek is blanched by fear, i. e., by the withdrawal of the blood, which leaves it white.
Blanch (&?;), v. i. To grow or become white; as, his cheek blanched with fear; the rose blanches in the sun.
