confusables note For stupid

Stupid, ignorant, and unintelligent are all used to refer to people or things that seem to show a lack of mental resources. Stupid is the most general and most insulting term, and can describe someone lacking in intelligence, wisdom, prudence, or mental quickness. Unintelligent refers to people or things that are lacking in capacity for learning, reasoning, or understanding. Ignorant, by contrast, generally means lacking in knowledge (not necessarily lacking in intelligence).
