From Middle English universe, from Old French univers, from Latin universum (“all things, as a whole, the universe”), neuter of universus (“all together, whole, entire, collective, general, literally turned or combined into one”), from uni-, combining form of unus (“one”) + versus (“turned”), perfect passive participle of vertō (“to turn”). Analyzable as uni- + -verse through backformation of -verse.
