What are the usings of "på","til" and "i" ?
There are many usings of "på","til" and "i" . What are they exactly ? Tusen takk !
"Jeg vil gå til der" is incorrect. Needs a defined destination, not just "der". E.g. "Jeg vil gå til der elgen bor". I want to go to where the moose lives.
As for all the other examples, they are difficult for me to explain (there are probably some who can). It's just how we say things. I suggest that you not concern yourself with the usage of pronouns in those kinds of expressions. Just learn them.
