Upper German refers to a group of dialects within the German language spoken primarily in the southern regions of Germany, Austria, and parts of Switzerland. This group includes notable dialects such as Bavarian and Swabian, which exhibit distinct phonetic and grammatical features compared to Standard German. The Upper German dialects are characterized by their unique vocabulary and pronunciation, making them quite different from Low German dialects. These variations reflect the rich cultural and historical influences in the regions where they are spoken, contributing to the diversity of the German-speaking world.
