Root Explanation

Coastline → It is formed from "coast" (from Old French *coste*, meaning the side or edge of land) and "line" (from Latin *linea*, meaning a string or line). The word "coastline" refers to the line that defines the edge of the land along the sea.

Memory Tip

Think of the 'edge' of the land ('coast') marked by a 'line' — that's what a coastline is.
