The word power comes from Latin and Old French roots tied to ability, strength, authority, and potential. It is rooted in the idea of being able, having capability, or holding mastery over something. Etymologically, power expresses the potential or capacity to act, affect, or influence—physically, socially, mentally, spiritually, or politically.
