Shtokavian dialect
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.
