I know this has been asked earlier, but in the cases I read through, the answer didn’t, in my opinion, be quite about what I was after, as the discussion was mostly about relative pronouns, although the general question was the same. I see this kind of usage very much in comics/lighter literary books and had to search for an easy example for this:
Der is aber übel gelaunt.
Well, he’s in a bad mood.
In an example like this, all I can think about is it being simply spoken language. Any thoughts? Or am I just thinking this “too difficultly”?
