Root Explanation

Involution is formed from "in-" (meaning in or into) and "volutio" (from "volvere", meaning to roll or turn). The word describes a process of rolling or turning inward, often used in contexts like biology or mathematics to indicate a complex or intricate development.

Memory Tip

Think of something 'turning inward' ('in-') and 'rolling' ('volutio') — that's why involution refers to a process that becomes more complex or intricate.
