Root Explanation

Straightedge → It is formed from "straight" (from Old English *streht*, meaning not bent or curved) and "edge" (from Old English *ecg*, meaning the boundary or margin of a surface). The word "straightedge" refers to a tool that has a straight boundary or margin, used for drawing straight lines.

Memory Tip

Think of a tool that has a 'straight' line ('straight') and a 'boundary' ('edge') — that's what a straightedge is used for.
