Root Explanation

Isoline is formed from "iso-" (from Greek "isos", meaning equal) and "line" (from Latin "linea", meaning line). The term refers to a line that connects points of equal value, such as temperature or pressure, on a graph or map.

Memory Tip

Think of 'equal' ('iso-') points being connected by a 'line' — that's what an isoline does.
