IPA: /ɪnˈvɒlʊʃən/
KK: /ɪnˈvɒlʊʃən/
The process of something folding in on itself or becoming more complex, often used in contexts like biology, mathematics, or medicine.
The involution of the uterus after childbirth is a normal part of recovery.
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.
Think of something 'turning inward' ('in-') and 'rolling' ('volutio') — that's why involution refers to a process that becomes more complex or intricate.
