Etymology

Origin of chief

First recorded in 1250–1300; Middle English, from Anglo-French chief, chef, Old French chef, from unattested Vulgar Latin capum, re-formation of Latin caput head

Explanation

A chief is a leader, often of a tribe or clan. Sometimes we call the president our "commander in chief." A chief is the head honcho, the big cheese, the top dog. Tribes are lead by chiefs, but so are firefighters (fire chief), policeman (police chief), and companies (Chief Executive Officer or CEO). When used as an adjective, chief describes the most important element or main ingredient of something. You couldn't make mac and cheese without the chief ingredients: macaroni and cheese.
