Root Explanation

Involute is formed from "in-" (meaning in or within) and "volut-" (from "volvere", meaning to roll or turn). The word describes something that is rolled inward or turned in upon itself.

Memory Tip

Think of something that is 'rolled in' ('in-') — that's why involute means something that is turned inward.
