I've seen some usages like this:
You've got there some really nice thing, you've got there.
He is a big jerk, he is.
Or something like that. I don't have an actual example right now, sadly, but I remember there was a verb at the beginning of the sentence and the same verb was repeated at the end.
Have you ever come across something like that? Can you point me to some sources where I can learn more about that?
Edit: I believe my question is different from the one suggested as I'm talking about usages where the verb itself is repeated, not the "do/would" in their place.
Edit2: So I guess my question is twofold: 1. Is that correct English/does anyone use it like that? (You've already answered that one.) 2. Any materials sources about this usage so I can learn when and how to use it correctly?
