Root Explanation

Obnoxious → It is formed from "ob-" (meaning against) and "noxius" (from Latin, meaning harmful or hurtful). The word "obnoxious" describes something that is harmful or offensive, often in a way that is difficult to tolerate.

Memory Tip

Think of something that is 'against' ('ob-') what is acceptable or pleasant, making it 'harmful' ('noxius') — that's why we find it obnoxious.
