Origin & History of “blind”

The connotations of the ultimate ancestor of blind, Indo-European *bhlendhos, seem to have been not so much ‘sightlessness’ as ‘confusion’ and ‘obscurity’. The notion of someone wandering around in actual or mental darkness, not knowing where to go, naturally progressed to the ‘inability to see’. Related words that fit this pattern are blunder, possibly from Old Norse blunda ‘shut one’s eyes’, blunt, and maybe also blend. By the time the word entered Old English, as blind, it already meant ‘sightless’, but ancestral associations of darkness and obscurity were retained (Pepys in his diary, for instance, writes of a ‘little blind (that is, dark) bed-chamber’ 1666), and traces of them remain in such usages as ‘blind entrance’.
