Torlakian dialect

Torlakian, or Torlak (Serbo-Croatian: Torlački/Торлачки, [tɔ̌rlaːt͡ʃkiː]; Bulgarian: Торлашки/Torlashki), is a group of South Slavic dialects of southeastern Serbia, southern Kosovo (Prizren), northeastern Republic of Macedonia (Kumanovo, Kratovo and Kriva Palanka dialects), western Bulgaria (Belogradchik–Godech–Tran-Breznik), which is intermediate between Serbo-Croatian, Bulgarian and Macedonian. According to UNESCO's list of endangered languages, Torlakian is vulnerable.

Some linguists classify it as an Old Shtokavian dialect or as a fourth dialect of Serbo-Croatian along with Shtokavian, Chakavian, and Kajkavian. Others classify it as a western Bulgarian dialect, in which case it is referred to as a Transitional Bulgarian dialect. Torlakian is not standardized, and its subdialects vary significantly in some features.

Speakers of the dialectal group are primarily ethnic Serbs, Bulgarians, and Macedonians. There are also smaller ethnic communities of Croats (the Krashovani) in Romania and Slavic Muslims (the Gorani) in southern Kosovo.
