Word Origin and First Recorded Use
The noun power entered Middle English through Anglo-French and Old French forms related to the idea of being able. Its deeper history traces to Vulgar Latin potēre and Latin posse, meaning “to be able.” Etymonline dates the noun’s appearance in English to around 1300. This refers to surviving written evidence, not necessarily the first time people spoke the word.
Over time, power developed meanings connected to physical strength, political authority, mechanical work, electricity, and mathematics. Its broad meaning explains why no single synonym works in every sentence.
