Boilersuit → The word is formed from "boiler" (from the Middle English *boiler*, meaning a vessel for boiling) and "suit" (from Old French *suite*, meaning a following or set of clothing). A boilersuit is a set of clothing designed to be worn over other clothes, often for protection in industrial settings, particularly where boiling or hot substances are present.
Think of a 'boiler' as a vessel for heat and 'suit' as a set of clothing — a boilersuit is protective clothing designed for hot environments.
