Root Explanation

**Spillway** → It is formed from "spill" (from Old English *spillan*, meaning to destroy or waste) and "way" (from Old English *weg*, meaning a path or route). A spillway is a route for water to flow away, often used to prevent overflow or flooding.

Memory Tip

Think of water 'spilling' away through a 'path' — that's why a spillway is a way for water to flow away.
