History
Etymology
The etymology of the noun is uncertain; suggested derivations include the following: * possibly related to Middle English blichening (“mildew or rust on grain, blight”), possibly related to Middle English bliken (“to gleam, shine; to turn pale”), from Old English blīcan (“to shine, sparkle”) (whence modern English blike (“(obsolete) to gleam, shine”); also compare Old Norse blikna (“to grow pallid”)), from Proto-West Germanic *blīkan (“to shine”), from Proto-Germanic *blīkaną (“to gleam, shine”), from Proto-Indo-European *bhleyǵ- (“to shine”); or * since sense 2.2 refers to a diseased condition of the skin, possibly from Middle English *bleighte, *bleȝte, from Old English blǣcþa (“leprosy”) (related to blǣċe (“an itching skin-disease”) and blǣċo (“leprosy; paleness”)), from Proto-West Germanic *blaik, ultimately from Proto-Germanic *blaikaz (“pale; white”), from Proto-Indo-European *bhleyǵ- (“to shine”). If so, the word is a doublet of bleak. The verb is derived from the noun.
