Middle High German

Middle High German (German: Mittelhochdeutsch), abbreviated MHG (Mhd.), is the term used for the period in the history of the German language between 1050 and 1350. It is preceded by Old High German and followed by Early New High German. In some uses, the term covers a longer period, going up to 1500.

Varieties

Middle High German is not a unified written language and the term covers two main dialect areas:

High German languages

The High German languages or High German dialects (German: Hochdeutsche Dialekte) comprise the varieties of German spoken south of the Benrath and Uerdingen isoglosses in central and southern Germany, Austria, Liechtenstein, Switzerland, and Luxembourg as well as in neighboring portions of Belgium (Eupen-Malmedy) and the Netherlands (Southeast Limburg), France (Alsace and northern Lorraine), Italy (South Tyrol), and Poland (Upper Silesia). They are also spoken in diaspora in Romania, Russia, the United States, Brazil, Argentina, Mexico, Chile, and Namibia.

The High German languages are marked by the High German consonant shift, separating them from Low German and Low Franconian (Dutch) within the continental West Germanic dialect continuum.

Classification

As a technical term, the "high" in High German is a geographical reference to the group of dialects that forms "High German" (i.e. "Highland" German), out of which developed Standard German, Yiddish and Luxembourgish. It refers to the Central Uplands (Mittelgebirge) and Alpine areas of central and southern Germany, it also includes Luxembourg, Austria, Liechtenstein and most of Switzerland. This is opposed to Low German, which is spoken on the lowlands and along the flat sea coasts of the North German Plain.

Upper German

Upper German (German:  Oberdeutsch ) is a family of High German dialects spoken primarily in the southern German-speaking area (Sprachraum).

Family tree

Upper German proper can be generally classified as Alemannic or Bavarian. However, the High Franconian dialects of the Franconian language, spoken up to the Speyer line isogloss in the north, are also considered part of the larger Upper German dialect group. Whether they should be included as part of Upper German or instead classified as Central German is an open question, as they have traits of both Upper and Central German and are frequently described as a transitional zone. Hence, either scheme can be encountered. Erzgebirgisch, usually lumped in with Upper Saxon on geographical grounds, is closer to East Franconian linguistically, especially the western dialects of Erzgebirgisch.
