Thuringian is anEast Central German dialect group spoken in much of the modern German Free State ofThuringia north of theRennsteig ridge, southwesternSaxony-Anhalt and adjacent territories ofHesse andBavaria. It is close toUpper Saxon spoken mainly in the state ofSaxony, therefore both are also regarded as one Thuringian-Upper Saxon dialect group. Thuringian dialects are among the Central German dialects with the highest number of speakers.
The Thuringian dialect is characterized by a rounding of the vowels, the weakening of consonants of Standard German (the lenition of the consonants "p," "t," and "k"), a marked difference in the pronunciation of the "g" sound (which is most common in the areas of North Thuringia and Saxony-Anhalt areas), and a highly-idiosyncratic, melodic intonation of sentences. The second German consonant shift manifested itself in a manner different from that elsewhere in the areas that spoke High German. In many words, "b" is pronounced as "w" or "f" would be inStandard German. For example, the wordaber (but) is pronounced as "awer". The Thuringian dialect has advanced beyond the stage ofbasilect.
