blanch

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.
