Conversation

I can't believe he did that again, it's so stupider than last time.

Right? You’d think he would learn from his mistakes.

It's like he's trying to prove that he can be even stupider than before.

Honestly, sometimes I wonder if he's actually doing it on purpose.

Synonyms & Antonyms

Root Explanation

Stupider → The word is formed from "stupid" (from Latin *stupidus*, meaning stunned or foolish) and the comparative suffix "-er" (indicating a higher degree). Thus, "stupider" means more foolish or more stunned than something else.

Memory Tip

Think of someone who is 'more foolish' — 'stupid' describes a lack of intelligence, and adding '-er' shows a greater degree of that quality.
