I’ve been bumping into all sorts of verbs that end with ん lately. The most recent example was 出来るん. What does this do to the verb?
My best guess after a small bit of research is that it’s either a shortening of な or んです, but I feel like I may be off, as I haven’t found any confirmation in articles/guides yet.
I would agree that it’s a very colloquial shortening of んだ / んです.
However you have to be careful to not mix it up with something like できん / 食べれん / 勝たん, which is short for 〜ない.
