The adjective is derived from Middle English purblind (“(adjective) completely blind; blind in one eye; near-sighted; (noun) near-sighted animal, specifically a hare”) [and other forms],[1] possibly from pur, pure (“completely, entirely”)[2] (ultimately from Proto-Indo-European *pewH- (“to be clean; pure”); influenced by pur- (prefix meaning ‘completely; forward; in advance’))[3][4] + blind (“sightless, blind”)[5][6][7] (ultimately from Proto-Indo-European *bʰlendʰ- (“to blend, mix up; to make cloudy または opaque”)).
Sense 4.1 (“completely blind”) was the original sense. The senses denoting partial blindness are possibly the result of confusion of the first element pur- with poor, perhaps through folk etymology.[6] (Compare parboil regarding per versus pars.)
The noun and verb[8] are derived from the adjective.
