German studies is the field of humanities that researches, documents and disseminates German language and literature in both its historic and present forms. Academic departments of German studies often include classes on German culture, German history, and German politics in addition to the language and literature component. Common German names for the field are Germanistik, Deutsche Philologie, and Deutsche Sprachwissenschaft und Literaturwissenschaft.
German dialects are the various traditional local varieties of the German language. Though varied by region, those of the southern half of Germany beneath the Benrath line are dominated by the geographical spread of the High German consonant shift, and the dialect continuum that connects German to the neighboring varieties of Low Franconian (Dutch) and Frisian. The varieties of German are conventionally grouped into Upper German, Central German and Low German; Upper and Central German form the High German subgroup.
