Root Explanation
Unpreparedness → It is formed from "un-" (meaning not), "prepared" (from Latin "parare", meaning to prepare), and "-ness" (meaning the state of being). The word "unpreparedness" means the state of not being prepared.
Memory Tip
Think of 'not' ('un-') being 'prepared' — that's why unpreparedness means the state of not being ready.
