How to say "misunderstanding" in Japanese

Choosing the right word
  • 勘違いかんちがいJLPT N2approx.Common
    noun, suru verb, intransitive verbCovers getting something wrong through your own mistaken thinking — a wrong guess or a mistaken idea. Typical when you misread a situation and later admit you had it all wrong.
    彼かれはクラスで一番いちばん頭あたまがいいと勘違かんちがいしている。↗
    He has the illusion that he is the smartest in his class.
  • 誤解ごかいJLPT N3approx.Common
    noun, suru verb, transitive verb, intransitive verbThe neutral, general-purpose word for a misunderstanding between people: one party takes the other's words or actions the wrong way. Choose this for ordinary communication failures with no special nuance.
    あなたを誤解ごかいしてしまってごめんなさい。↗
    I'm sorry I misunderstood you.
  • 思い違いおもいちがいCommon
    noun, suru verb, intransitive verbFits being under a false impression or holding a mistaken idea — the picture in your head is wrong. It overlaps with 勘違い, and either word will do when you simply have something wrong.
    彼かれは思い違おもいちがいをしているらしい。↗
    It appears that he is mistaken.
  • 錯覚さっかくJLPT N1approx.Common
    noun, suru verb, transitive verb, intransitive verbReally means 'illusion' — an optical illusion or a false belief you are under. As 'misunderstanding' it is marginal: seldom the word you want for an ordinary mix-up between people.
  • 行き違いいきちがいJLPT N1approx.Common
    nounCovers the 'crossed wires' kind of misunderstanding, where two parties each act on different assumptions and things get out of step. Its other senses, disagreement and estrangement, sit close by.

Use 誤解 for a neutral misunderstanding between people, 「勘違い」 or 「思い違い」 for your own mistaken idea or impression, 「行き違い」 for crossed wires between two parties, and reserve 錯覚 for illusions and false beliefs rather than ordinary mix-ups.
