"Stupider" är inte ett accepterat engelsk ord. Det finns inte i några engelska lexikon. Snälla, ta bort det.. det skär i mina ögon att se det. Här följer några exempel: An adjective usually follows (somewhat loose) rules for the comparative and superlative form. We would say quick, quicker, quickest and intelligent, more intelligent, and most intelligent. Generally words that have more syllables would use the more/most rule. However, there are exceptions. One says fun, more fun, and most fun instead of fun, funner, and funnest. Likewise with stupid. You would say "more stupid" rather than "stupider" because it sounds less stupid!
He is stupid. ( adjective )
He is more stupid than jack . (comparative).
He is the most stupid person I have ever met. ( superlative ).
I have never seen such stupidity before ( noun ).
