Root Explanation

Hornstone is formed from "horn" (from Old English "horn", meaning a hard, pointed projection) and "stone" (from Old English "stan", meaning rock or stone). The word refers to a type of hard stone that resembles horn in texture or appearance.

Memory Tip

Think of a hard, pointed projection ('horn') combined with rock ('stone') — that's why hornstone refers to a hard stone that looks like horn.
