Lake Ohrid. During this period the valley of Skumbin constituted roughly the border between the Latin and the Greek speaking area. The river is roughly the geographical dividing line between Tosk and Gheg Albanian dialects, with Gheg spoken north of the Shkumbin and Tosk south of it. The dialectal split occurred after Christianisation of the region (4th century AD), with the river as the historic dialectal boundary which straddled the Jireček line.
