Prague German

Prague German (German: "Prager Deutsch", Czech: "Pražská němčina") was the dialect of German spoken in Prague in what is now the Czech Republic. The written form of this dialect from the Luxembourg rule played an important role in the history of the German language for its balancing function between the written upper Austrian and southern German dialects and eastern Central dialects of central Germany, which later developed the spelling of Modern German writing (Hochdeutsch).
