📝 Usage Notes

no chance of; definitely not possible

📖 How to use it

Expresses that something has absolutely no chance of happening or being true; a strong negative assertion.

Attaches to Attach to the ます-stem of verbs (the form used before ます, e.g., でき, 行き). For verbs like する, use し; for くる, use き.

っこない is a colloquial, emphatic way to say something is impossible. It's stronger than just using the negative form of a verb; it asserts that there's no way, no chance. You'll hear it in everyday speech, often with frustration or certainty.

It attaches to the ます-stem of a verb. For example, from できる (can do) you get できっこない (no way can do). From 行く (go) you get 行きっこない (no way will go). It's not used with nouns or adjectives directly.

This pattern is common in casual conversation but can sound blunt or even rude if used in formal settings. It's fine among friends or when you want to emphasize your opinion strongly.

Not わけがない わけがない also expresses strong impossibility but is slightly more logical and can be used in more formal contexts. っこない is more emotional and colloquial. Also, っこない always attaches to the ます-stem, while わけがない attaches to the plain form (verb or adjective) or noun + な.
Register Spoken, casual; not used in formal writing or polite speech.
