property

lack of intelligence or good sense
The state of being stupid, when a person or thing cannot think well or often makes very bad choices.
用法パターン：
[someone]'s stupidity
よくある間違い：
Learners sometimes say *"stupidness"* instead of *"stupidity"*. In standard English, *"stupidity"* is the normal noun for the quality of being stupid. Also, this noun is usually uncountable in this sense, so we do not normally say *"many stupidities"* when we mean general lack of intelligence; we say *"a lot of stupidity"* instead.
類義語
idiocy (Stronger and more insulting than "stupidity"; often suggests extreme or shocking lack of sense.)
対義語
intelligence (Names the opposite quality: the ability to think, understand, and judge well.)

a stupid act or remark
A single stupid action or stupid thing that someone says.
用法パターン：
an act of stupidity by [someone]
よくある間違い：
Learners often do not realize that *"stupidity"* can be used as a countable noun for separate actions, usually in fixed phrases like *"an act of stupidity"* or *"a moment of stupidity"*. Saying *"a stupidity"* by itself is grammatically possible but quite rare in modern English; it is more natural to say *"a stupid thing"*.
類義語
blunder (Focuses on a serious mistake, especially in work or plans; less directly insulting about general intelligence than "stupidity".)
対義語
wise decision (Describes a choice that shows good judgment, the opposite of a specific stupid act.)
