• 発音: /joː.tɕi/

意味

Childish; infantile; immature; naive. Describes behaviour, thinking, or expression that is underdeveloped or inappropriate for one's age.

A na-adjective with a primary critical sense: calling someone's attitude or reasoning 幼稚 is a pointed rebuke of their immaturity. It differs from 子供っぽい (childlike) in that it is always negative — there is no charming sense of childlike innocence. Also used in the compound 幼稚園 (kindergarten), which is a neutral, non-derogatory usage. In the evaluative sense, 幼稚な考え方 or 幼稚な言動 are common collocations.

例文
