Did You Know?

Coeval comes to English from the Latin word coaevus, meaning "of the same age." "Coaevus" was formed by combining the "co-" prefix ("in or to the same degree") with Latin aevum ("age" or "lifetime"). The root "ev" comes from "aevum," making words such as "longevity," "medieval," and "primeval" all near relations to "coeval." Although "coeval" can technically describe any two or more entities that coexist, it is most typically used to refer to things that have existed together for a very long time (such as galaxies) or that were concurrent with each other in the distant past (parallel historical periods of ancient civilizations, for example).

Origin and Etymology of coeval

Latin coaevus, from co- + aevum age, lifetime — more at aye
