Forming it

How to use it

States the CONCLUSION first, then explains the reason. Used in argumentative writing and presentations.

  • Fixed pair: if you open with 「なぜなら」, the end of the sentence MUST have 「から(だ)」 — missing 「から」 is the most common mistake.
  • The order is reversed from ordinary 「から/ので」: the conclusion comes first and the reason comes after — this makes arguments clearer in writing.
  • A softer variant: 「なぜかというと~からです」 (used in speech); a formal one: 「というのは~からである」.

Examples

  • I love this restaurant. That is because the food is delicious.

  • She failed the exam. That is because she hardly studied.

Keep in mind

  • Must end with 「から(だ)」.
  • A sentence-initial conjunction; not used to join within a sentence.

Common mistakes

  • Wrongこの店(みせ)が好(す)きだ。なぜなら、料理(りょうり)がおいしい。

    I like this restaurant. The reason is the food is good.

    Correctこの店(みせ)が好(す)きだ。なぜなら、料理(りょうり)がおいしいからだ。

    「なぜなら」 must be paired with 「から(だ)」 at the end.

  • Wrong料理(りょうり)がおいしいなぜならこの店(みせ)が好(す)きだ。

    I like this restaurant. The reason is the food is good.

    Correctこの店(みせ)が好(す)きだ。なぜなら、料理(りょうり)がおいしいからだ。

    The conclusion comes FIRST; 「なぜなら」 opens the explanatory sentence.

Exam tips

  • 「なぜなら~からだ」 = the reason is...; always paired, conclusion comes first.
