The Prizren–Timok dialect (Serbian: призренско–тимочки дијалект / prizrensko–timočki dijalekt) is the name given by Serbian linguists to classify transitional Torlak dialects spoken in Southern Serbia and Kosovo – an area spanning from Prizren in the south to the Timok river in the north – as subdialects of Old-Shtokavian. Its eastern border, starting from Zaječar, roughly forms the border with Bulgaria.
