Tombstone → It is formed from "tomb" (from Old English *tomb*, meaning a burial place) and "stone" (from Old English *stan*, meaning a rock or stone). A tombstone is a stone marker placed at a burial site to commemorate the deceased.
Think of a 'burial place' ('tomb') marked by a 'rock' ('stone') — that’s why a tombstone is a stone that marks where someone is buried.
