誰だれも

expression

everyone; anyone

In affirmative contexts, often appears as 誰もが to mean that all people are included. The English 'anyone' is usually better expressed by 誰でも when it means 'whoever' or 'any person at all.'

• 誰だれもが彼かれの成せい功こうを喜よろこんだ。

  Everyone was happy about his success.

• この歌うたは誰だれもが知しっている。

  Everyone knows this song.

expression

no one; nobody; not anyone

Used with a negative verb or negative predicate: 誰も来ない, 誰も知らない, 誰もいない. Literally it functions like 'not anyone.'

• 教きょう室しつには誰だれもいなかった。

  There was no one in the classroom.

• その答こたえを誰だれも知しらなかった。

  Nobody knew the answer.
