blind (adj.)youdaoicibaDictYouDict[blind 词源字典]
Old English blind "blind," also "dark, enveloped in darkness, obscure; unintelligent, lacking mental perception," probably from Proto-Germanic *blinda- "blind" (cognates: Dutch and German blind, Old Norse blindr, Gothic blinds "blind"), perhaps, via notion of "to make cloudy, deceive," from an extended Germanic form of the PIE root *bhel- (1) "to shine, flash, burn" (see bleach (v.)). Compare Lithuanian blendzas "blind," blesti "to become dark." The original sense would be not "sightless" but rather "confused," which perhaps underlies such phrases as blind alley (Chaucer's lanes blynde), which is older than the sense of "closed at one end" (1610s).
The twilight, or rather the hour between the time when one can no longer see to read and the lighting of the candles, is commonly called blindman's holiday. [Grose, 1796]
