Rules for usage of Polish cases?
Ugh! Polish cases are so hard to figure out! I've attempted to learn Polish before, but I've been unable to get past the basics because I can't figure out how the cases work, and I haven't been able to find a single page on the Interwebz where definitions of the seven Polish cases, the usage of those cases, and the creation of the forms of Polish words corresponding to them are explained. Can someone either link me to a page that does, or just explain them here?
