The word "jack" traces back to the Middle English "jakke," a generic term for a man or servant, derived from the Old French "Jacques" (a variant of "James"). Over time, it evolved into a placeholder name for common objects or tools (e.g., "jackknife," "jack-of-all-trades"). Its use in card games (16th century) and mechanical devices (17th century) reflects its versatility as a label for utilitarian or subordinate roles.
