  • pair from (Middle English):

    Pair comes from Latin paria ‘equal things’, formed from par ‘equal’. Latin par also lies behind compare (Late Middle English) ‘to pair with, bring together’; disparage (Middle English) originally ‘a mis-pairing especially in marriage’, later ‘to discredit’; nonpareil (Late Middle English) ‘not equalled’ (taken directly from the French); par (late 16th century) ‘equal’, a golfing term from L19th; parity [L16] ‘equalness’; peer (Middle English) ‘equal’; and umpire (Middle English) originally noumpere, from the same source as nonpareil, because an umpire is above all the players. A noumpere was later re-interpreted as ‘an umpire’ and the initial ‘n’ was lost.
