Word Origin & History

blind  (adj.)
O.E. blind "blind," probably sharing with blend a P.Gmc. base *blindaz, from PIE base *bhlendh- "to glimmer indistinctly, to mix, confuse" (cf. Lith. blendzas "blind," blesti "to become dark"). The original sense, not of "sightless," but of "confused," perhaps underlies such phrases as blind alley. The verb is O.E. blendan, influenced in M.E. by the adj. The noun meaning "anything that obstructs sight" is from 1535. Blindman's bluff is from 1590. Blind date is from 1920s. Blind side "unguarded aspect" is from 1606; the verb meaning "to hit from the blind side" (written as one word) first attested 1968, Amer.Eng., in ref. to U.S. football.
"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." [1796]
