Shades of meaning
To whiten is to make white in general, but commonly it means to overspread with white coloring-matter. Bleach and blanch both signify to whiten by depriving of color, the former permanently, as linen; the latter either permanently (as, to blanch celery) or temporarily (as, to blanch the cheek with fear). To whitewash is to whiten superficially, especially by false approval.
