Mantelpiece → It is formed from "mantel" (from Old French *mantel*, meaning a covering or cloak) and "piece" (from Latin *pax*, meaning a part or section). The word refers to a piece or section that covers or adorns the area above a fireplace.
Think of a 'covering' ('mantel') that is a 'part' ('piece') of a fireplace — that's what a mantelpiece is.
