Albanian dialects

The Albanian language is composed of many dialects, divided into two major groups: Gheg and Tosk. The Shkumbin river is roughly the geographical dividing line, with Gheg spoken north of the Shkumbin and Tosk south of it.

The characteristics of the Albanian dialects Tosk and Gheg, in the treatment of the native and loanwords from other languages, have led to the conclusion that the dialectal split preceded the Slavic migration to the Balkans According to Hamp, the rarity of ancient Greek loans imply that proto-Albanian developed north of the Jireček Line, while the isogloss split dates to the post-Roman 1st Millennium AD, the speech area straddling the Line, then spreading further.

Gheg is divided into four sub-dialects: Northwest Gheg, Northeast Gheg, Central Gheg, and Southern Gheg. Northwest Gheg is spoken throughout Montenegro, northwestern Kosovo (west of Pejë), Lezhë, northwestern Mirditë, Pukë, and Shkodër. Northeast Gheg is spoken throughout most of Kosovo, Preševo, Has, northeastern Mirditë, Kukës, Tropojë, and northern Tetovo. Central Gheg is spoken in Debar, Gostivar, Krujë, Peshkopi, southern Mirditë, Mat, eastern Struga, Kumanovo, and southern Tetovo. Southern Gheg is spoken in Durrës, northern Elbasan, northern Peqin, Kavajë, northwest Struga, and Tirana. One fairly divergent dialect is the Upper Reka dialect, which is however classified as Central Gheg. There is also a diaspora dialect in Croatia, the Arbanasi dialect.
