blanch
Blanch (verb) means to turn pale or white.
Etymology
Came into English from Middle English blaunchen, from Old French blanchir, from Old French blanc (“white”), from Early Medieval Latin blancus, from Frankish *blank, from Proto-Germanic *blankaz (“bright, shining, blinding, white”), from Proto-Indo-European *bʰleyǵ- (“to shine”). It is cognate with blench (“to deceive, to trick”) through Proto-Indo-European, which gives blanch its other etymology.
