Etymology

The word "pair" originates from the Latin paria, meaning "equals" or "a set of two." It entered Old French as paire, retaining the sense of duality, and was later adopted into Middle English. The core idea of "two matched or corresponding items" has remained consistent throughout its evolution. Unlike many English words with complex morpheme structures, "pair" is monomorphic—its meaning is indivisible in modern English, deriving wholly from its Latin root.
