Root Explanation

Immaturity is formed from "im-" (meaning not) and "maturus" (meaning ripe or mature) and the suffix "-ity" (meaning the state or condition of). The word describes the state of not being mature or fully developed.

Memory Tip

Think of 'not' ('im-') being 'ripe' or 'mature' ('maturus') — that's why immaturity means the state of not being fully developed.
