Synonyms & Antonyms

Root Explanation

Untidy → It is formed from "un-" (meaning not) and "tidy" (from Old English *tidy*, meaning in order or neat). The word "untidy" means not in order or messy.

Memory Tip

Think of 'not' ('un-') being added to 'neat' or 'in order' ('tidy') — that's why untidy means messy or disorganized.
