Other forms: universes
The universe is absolutely everything that exists. The observable universe, across the universe, the expanding universe.
The observable universe is about 93 billion light years across, which is larger than its age in light years because space itself has expanded. Whether anything lies beyond it is not answerable by observation. Figuratively a universe is a self-contained world: the universe of the novel. Note universal; and that the Latin means turned into one, which is a rather good definition.

Built from
From Middle English universe. 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.
