- Transitional Bulgarian dialects
The Transitional Bulgarian dialects are a group of Bulgarian dialects which are located west of the
yatboundary and are part of the Western Bulgarian dialects. On Bulgarian territory, the Transitional dialects occupy a narrow strip of land along the Bulgarian border with Serbia, including the regions of Tran, Breznik, Godechand Belogradchik. They also cross the border to include the dialects or subdialects of the Bulgarian minority in the Western Outlands(the regions of Tsaribrodand Bosilegrad), Bulgarian territories transferred to Serbiaby the Treaty of Neuillyas punishment for Bulgarian participation in World War Ion the side of the Central Powers. The Transitional dialects are akin and closely related to the Torlak dialects spoken in southwestern Serbia and are part of the gradual transition from Bulgarian to Serbian. The Bulgarian Transitional dialects and the Serbian Torlak dialects are characterised by mixed, predominantly Serbian phonology and predominantly Bulgarian morphology.
