How to say "improper" in Japanese
Choosing the right word
- 不可ふかno-adjective, na-adjective, noun (suffix)A flat verdict that something is wrong, bad, or unjustifiable — 'not acceptable' — rather than a description of improper manners; well known as the failing grade.
- i-adjectiveImproper in the sense of unseemly or immodest — conduct, speech, or manner that looks disgraceful to others; the natural word for behavior that is shameful rather than logically wrong. Usually written in kana.
- 不穏当ふおんとうna-adjective, nounImproper in the sense of inappropriate or unfair — a judgment on remarks, statements, or the way something is handled, rather than on a person's manners or appearance.
- 不相応ふそうおうna-adjective, nounImproper in the sense of unsuited or undeserved — out of keeping with the person, as when something is more than one's position or deserts warrant; it questions the match, not the manner.
- 不似合いふにあいna-adjective, nounImproper in the sense of unbecoming — something that does not suit the person, an ill-matched fit; about suitability to the individual rather than about wrongdoing or shame.
Choose 「はしたない」 for unseemly, immodest conduct, 不穏当 for inappropriate or unfair remarks, 不相応 for what is undeserved or out of keeping with the person, 「不似合い」 for the unbecoming, and 不可 for a flat verdict of wrong or unacceptable.
