Old High German

Old High German (OHG, German: Althochdeutsch, German abbr. Ahd.) is the earliest stage of the German language, conventionally covering the period from around 700 to 1050 AD. Coherent written texts do not appear until the second half of the 8th century, and some treat the period before 750 as "prehistoric" and date the start of Old High German proper to 750 for this reason. There are, however, a number of Elder Futhark inscriptions dating to the 6th century (notably the Pforzen buckle), as well as single words and many names found in Latin texts predating the 8th century.

Characteristics

The main difference between Old High German and the West Germanic dialects from which it developed is that it underwent the Second Sound Shift or High German consonant shift. This is generally dated approximately to the late 5th and early 6th centuries—hence dating its start to around 500 AD. The result of this sound change is that the consonantal system of German remains different from all other West Germanic languages, including English and Low German. Grammatically, however, Old High German remained very similar to Old English, Old Dutch, and Old Saxon.

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.
