The Albanian language is composed of many dialects, divided into two major groups: Gheg and Tosk.[1] The Shkumbin river is roughly the geographical dividing line, with Gheg spoken north of the Shkumbin and Tosk south of it.[2]
^Brown and Ogilvie (2008), p. 23. The river Shkumbin in central Albania historically forms the boundary between those two dialects, with the population on the north speaking varieties of Geg and the population on the south varieties of Tosk.
