Question about the usage of мне
Принадлежать = to belong In the song моя игра from баста and гуф is a chorus and I quote: "Она мне принадлежит и таким же как и я". On the part она мне принадлежит (=she belongs to me) is my question focused. Why use the prepositional case of me and not the accusative case? I think accusative is right because принадлежит says something about me. Why is it different here?
"Мне" can be in the prepositional case, but it can also be in the dative case. When using принадлежать/to belong, the owner is the indirect object. If you don't know what that is, I suggest you look at this. The indirect object takes the dative case. This has some good info on how to form that case.
"Принадлежать к" is also valid followed by the dative case AFAIK, but I'm not entirely sure when the "к" is necessary.
