How to use it

Flatly denies a possibility, in a conversational tone. Only used with close, familiar people.

  • 「Vっこない」 = there's no way…: 「そんな難しい問題、私に分かりっこない」.
  • Attaches to the MASU-STEM (the catalog entry that says "negative stem" is incorrect). With the potential form, it attaches after the potential form: 「勝てっこない」.
  • Strongly conversational — written language uses 「~はずがない/~わけがない」.

Examples

  • With this much snow, there is no way we will make it in time.

  • We have not practiced, so there is no way we can beat that team.

Keep in mind

  • Attaches to the masu-stem.
  • Colloquial, not used in written language.

Common mistakes

  • Wrong分(わ)からないっこない。

    There's no way I wouldn't understand.

    Correct分(わ)かりっこない。

    Attaches to the MASU-STEM; 「っこない」 itself already carries a negative meaning.

  • Wrong(報告(ほうこく)書(しょ)に)達成(たっせい)できっこない。

    There's no way it can be achieved.

    Correct(報告(ほうこく)書(しょ)に)達成(たっせい)できるはずがない。

    Written documents use 「はずがない」; 「っこない」 is conversational.

Exam tips

  • 「っこない」 = there's no way… (conversational); attaches to the masu-stem.
