The Prizren–Timok dialect (Serbo-Croatian: призренско–тимочки дијалект / prizrensko–timočki dijalekt) is the name given by Serbian linguists to classify transitional Torlakian dialects spoken in Eastern and South 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.
