Old English bletsian, bledsian, Northumbrian bloedsian "to consecrate, make holy, give thanks," from Proto-Germanic *blodison "hallow with blood, mark with blood," from *blotham "blood" (see blood (n.)). Originally a blood sprinkling on pagan altars. This word was chosen in Old English bibles to translate Latin benedicere and Greek eulogein, both of which have a ground sense of "to speak well of, to praise," but were used in Scripture to translate Hebrew brk "to bend (the knee), worship, praise, invoke blessings." L.R. Palmer ("The Latin Language") writes, "There is nothing surprising in the semantic development of a word denoting originally a special ritual act into the more generalized meanings to 'sacrifice,' 'worship,' 'bless,'" and compares Latin immolare (see immolate). Meaning shifted in late Old English toward "pronounce or make happy," by resemblance to unrelated bliss. No cognates in other languages. Related: Blessed; blessing.

Old English blind "blind," also "dark, enveloped in darkness, obscure; unintelligent, lacking mental perception," probably from Proto-Germanic *blinda- "blind" (source also of 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." Compare Lithuanian blendzas "blind," blesti "to become dark."
