vigor
UK: ˈvɪɡə | US: ˈvɪɡər
n. physical or mental strength, energy, or enthusiasm
n. active force or vitality
The word "vigor" originates from the Latin vigor, meaning "active strength" or "liveliness," derived from vigēre ("to be lively or thrive"). The root vig- is linked to vitality and growth, seen in related words like "vigilant" (watchful energy) and "vegetate" (originally "to grow"). The suffix -or denotes a state or quality, common in Latin-derived nouns (e.g., "honor," "terror"). Over time, "vigor" retained its core sense of dynamic energy, reflecting both physical and mental vitality.
