Sorbian languages
The Sorbian, Lusatian or Sorbian-Lusatisan langauges are members of the West Slavic branch of languages spoken in eastern Germany. They are also known as Wendish.
There are two languages - Upper Sorbian (hornjoserbsce) spoken in Saxony and Lower Sorbian (dolnoserbski) spoken in Brandenburg. This area is known as Lusatia (Łužica or Lausitz in German).
Both languages have dual grammatical number. This is used when when exactly two people or things are meant and is addition to singular and plural.
In Germany they are officially recognized and protected as minority languages.
Sorbian is also spoken in a small Wendish settlement in Lee County, Texas, and until recently newspapers were published in Wendish there. It has been heavily influenced by surrounding speakers of German and English.
