uniformity

Origin

From Late Middle English uniformite, uniformitie (“conformity or equality among several parts; similar degree”), borrowed from Old French uniformité (“uniformity”) (modern French uniformité), or from its etymon Late Latin ūniformitās, from Latin ūnifōrmis (“having only one form or shape, uniform”) + -itās (a variant of -tās (suffix forming feminine abstract nouns indicating a state of being)). Ūnifōrmis is derived from ūni- (prefix meaning ‘one’) (ultimately from Proto-Indo-European *h₁óynos (“one”)) + -fōrmis (suffix meaning having the form of) (from fōrma (“appearance, form, shape”); further etymology unknown). By surface analysis, uniform + -ity.
