From an English perspective--including mine since I'm learning Japanese using English, I felt that 違う sounded strong, this may be from the tendency to respect others' opinions on English, that implying others to be wrong may be seen as rude. But from the situation that I've seen it was used, and based on a native I asked; 違う was used freely like a 'no' in English when you disagree with the information being said. For example, if we were asked ”大学生ですか” the native Japanese that I asked said it's fine to reply with ”違います” if we aren't, and that it can be used in other formal situations. But another non-native yet advanced Japanese speaker claimed the word to be strong and can be rude. I know since I already got confirmation from a native speaker, it should be done, but I'm seeking more info, when is it fine to use 違う and can it be rude?

I rather read your remark on English connotation interestingly, but anyway, there do exist some cases where the superficial form and the meaning 違う, in any language.

Effectively, you can just take 違う as Japanese way to say "it's not", because:

あなたはプログラミングしますか? [ordinary verb]
→ いいえ、しません。

あなたはプログラマーですか? [copula]
→ いいえ、プログラマーじゃありません。 (too long!)
→ いいえ、*じゃありません。 (ungrammatical!)
→ いいえ、違います。

So this is our pragmatic solution for this specific linguistic problem, and not much related to anything cultural. Incidentally, in casual speech we sometimes simply say じゃない(です) in this context, which is obviously not a good grammar, but as short as 違います/違う in mora count.

  • Ah, is it fine to use them both in formal and casual situations? Is there also a politer and ruder version?

  • @奇興好 Only polite and non-polite, 違います and 違う. I don't think we have any other synonymous "politer and ruder" phrases. It's an oral expression, so better be avoided in formal writing. Outside of that, I can't think of situations it won't fit (perhaps you should be careful before using it against the emperor?). Jun 19, 2020 at 2:56
  • @奇興好 Forgot to mention ちげえ, which is a slangy pronunciation, and sounds vulgar. Jun 19, 2020 at 8:12
  • there's also kansai-ben ちゃう Jun 19, 2020 at 16:17

違う has another meaning: "Different".


This sentence is not impolite。
