pair

pair: [13] Like English par [17], parity [16], and peer ‘noble’ [13], pair comes ultimately from Latin pār ‘equal’, a word of unknown origin. Its derivative paria ‘equal things, similar things’ passed into English via Old French paire. Other English descendants of Latin pār include compare, disparage [14], nonpareil [15], and umpire.
