〜っこない~kkonai
absolutely impossible
Use 「〜っこない」 in everyday speech to firmly say that something is impossible, based on your judgment.
How it works

Can you memorize this many words in one week? Look at the picture and think about why the speaker is certain it cannot be done.

「っこない」 strongly rules out a possibility. It means “there is absolutely no way,” with a very firm tone.

This is an everyday spoken expression. Even with 「です」 at the end, the strong negative tone remains.

It expresses the speaker’s judgment. Telling someone “you could never do that” can sound presumptuous.

In the example, the pattern is 分かります→分かり+っこない. Remove 「ます」.
