Root Explanation

Rottenstone is formed from "rotten" (from Old English "rotian", meaning to decay or decompose) and "stone" (from Old English "stan", meaning rock or stone). The word refers to a type of soft, abrasive material made from decomposed stone, used in polishing.

Memory Tip

Think of something that has 'decayed' ('rotten') and is made of 'stone' — that's why rottenstone is a soft material used for polishing.
