Nikola, that is really interesting and unique. In Switzerland we have Swiss German dialects that are spoken in every day life but the written language learned at school is Hochdeutsch, the standard German. Newspapers, literature use the standard German. The exact same phenomenon is present in the whole Arabic world.
So it is quite unique to have two versions of the same language spoken and written in such a relative small territory.
I thought that Slovak and Czech were similar. I realize I have still many things to learn.
