The Lusatian dialects (Standard German: Lausitzisch) are East Central German (High German) dialects spoken in southern Brandenburg and eastern Saxony. The name "Lusatian" derives from the term Lusatia, meaning the dialects of Lusatia. They are most closely related to Silesian German.
Berlin and Brandenburg originally lay in the Low German language area. Through immigration to Berlin from (then) Central German-speaking regions like Silesia and Saxony, the city's Low German dialect has been strongly influenced by Central German, so that it evolved from a Low German into a Central German (High German) variant, which then spread from Berlin to the surrounding areas of Brandenburg.
The Slavic languages of Lower and Upper Sorbian, which are spoken in Lusatia as well, are also sometimes referred to as Lusatian languages.
