Root Explanation
Unorganized → It is formed from "un-" (meaning not) and "organized" (from Latin "organizare", meaning to arrange or structure). The word "unorganized" means not arranged or lacking structure.
Memory Tip
Think of 'not' ('un-') having a 'structure' ('organizare') — that's why unorganized means lacking arrangement.
