Unripeness → It is formed from "un-" (meaning not) and "ripe" (from Old English "rīpe", meaning mature or ready for harvest) and "-ness" (meaning the state of). The word "unripeness" refers to the state of not being ripe or mature.
Think of 'not' ('un-') being combined with 'mature' ('ripe') to remember that 'unripeness' means the state of not being mature.
