    • whiten Synonyms Whiten, Bleach, Blanch, Etiolate. Whiten may be a general word for making white, but is chiefly used for the putting of a white coating upon a surface: as, a wall whitened by the application of lime; the sea, whitened by the wind. White for whiten is old-fashioned or Biblical. Bleach and blanch express the act of making white by removal, change, or destruction of color. Bleaching is done chemically or by exposure to light and air: as, to bleach linen or bones. Blanching is a natural process: celery and other plants are blanched or etiolated by excluding light from them; cheeks are blanched by fear, when the blood retires from their capillaries and leaves them pale. See also defs. 5 and 6 under blanch.
