Origin & History of “compare”

Compare comes via Old French comparer from Latin comparāre ‘couple, match’, a verb based on the adjective compar ‘equal’, a compound formed from the prefix com- ‘mutually’ and pār ‘equal’ (source of English pair, peer, and parity). The Latin derivative noun comparātiō gave Old French comparesoun and hence English comparison (14th c.).
