Pattern

  • どうして+文+か どうして + sentence + か
  • 〜のですか/んですか …のですか (a natural way to ask a reason)

How to use it

どうして + sentence asks why something happened. どうして学校を休みましたか asks the reason for being absent.

How to answer

Answer with 〜からです or 〜ので (風邪をひいたからです).

Difference from なぜ

The meaning is almost the same. どうして suits conversation; なぜ is a little more formal and also used in writing.

Examples

  • どうして学校(がっこう)を休(やす)みましたか。

    Dōshite gakkō o yasumimashita ka.

    Why were you absent from school?

  • どうしてご飯(はん)を食(た)べないのですか。

    Dōshite gohan o tabenai no desu ka.

  • どうしてこの店(みせ)が好(す)きですか。

    Dōshite kono mise ga suki desu ka.

Common mistakes

  • Finish the answer with 〜からです. Just 〜です does not read as a reason.
  • Said strongly, it can sound like blame.
