[Probably translation of German Obersorbisch : ober, higher (from the fact that southern Lusatia is more mountainous and at a higher elevation than northern Lusatia) + Sorbisch, Sorbian.]
There is also a linguistic divide between speakers of Upper Sorbian, who live in Upper Lusatia in Saxony, and those who speak Lower Sorbian, based mainly in Lower Lusatia, Brandenburg.
