〜ものか

JLPT N2:

absolutely not / as if

A rhetorical question that strongly rejects an idea or declares a firm refusal: “as if…!” or “there is no way…”.

How to form it

  • Put ものか after the plain form: 信(しん)じるものか.
  • ものですか is more polite in shape, and もんか is colloquial, but both can keep the same emphatic force.

Examples

あんな店(みせ)には二度(にど)と行(い)くものか。

There is no way I will ever go to that shop again.

そんなうまい話(はなし)を信(しん)じるものですか。

As if I would believe a story that convenient.

Common mistakes

  • Reading it as a genuine question.
  • Confusing it with 〜ものだから, which gives a reason or excuse.

Same form, different meaning
