How to use it

Turning a yes/no question into an indirect clause serving as the content of knowing, asking, checking, or deciding.

  • かどうか packages the two possibilities "whether or not" into one clause. It's usually followed by 分かる, 知る, 聞く, 調べる, 確認する, or 決める.
  • Do not use かどうか after specific question words such as いつ/どこ/だれ; in that case, just keep the question word + か: いつ来るか分かりません.

Examples

  • I will check the forecast to see whether it will rain tomorrow.

  • Please check whether this answer is correct.

Common mistakes

  • Wrong田中(たなか)さんがどこにいるかどうか知(し)りません。

    Correct田中(たなか)さんがどこにいるか知(し)りません。

    Since the question word どこ is already present, only use ~か, don't add どうか.

Exam tips

  • Yes/no questions → かどうか; questions with いつ・どこ・だれ・何 → just か.
