Etymology

Origin of vigor

First recorded in 1300–50; Middle English vigo(u)r, from Anglo-French; Middle French vigeur, from Latin vigor “force, energy,” from vig(ēre) “to be vigorous, thrive” + -or -or 1

Explanation

Aside from mental or physical vitality, the noun vigor can be applied to an imaginative style of thought or expression and also to a forceful intensity.
