The word traces back to Latin vita ("life"), which also gives us related terms like vital ("essential to life") and revitalize ("to restore life/energy"). The suffix -ity systematically converts adjectives into nouns (e.g., clarity from clear). Vitality thus encapsulates the concept of "life-force" or "energy," evolving from concrete biological vitality to metaphorical vigor (e.g., "the vitality of a performance").
