Subbalkan dialect explained

The Subbalkan dialect is a Bulgarian dialect, which is part of the Balkan group of the Eastern Bulgarian dialects. Its range includes the northeastern part of Bulgarian Thrace, i.e. the regions of Burgas, Sliven, Yambol, Stara Zagora and Chirpan. As a result of the mass population movements that affected eastern Bulgaria during the 19th and the beginning of the 20th century, speakers of the Subbalkan dialect have moved en masse to northeastern Bulgaria and now form a vast portion of the population of the districts of Varna, Dobrich and Balchik. Some of these also went as far as Bessarabia establishing numerous colonies there. Nowadays, a large part of the Bessarabian Bulgarians speak this dialect. The most significant feature of the Subbalkan dialect, as in all Balkan dialects, is the pronunciation of Old Church Slavonic ѣ (yat) as pronounced as /ʲa/ or pronounced as /ɛ/, depending on the character of the following syllable.

Phonological and morphological characteristics

As a result of its specific characteristics, the Subbalkan dialect is usually considered to be a transitional dialect between the Balkan dialects and the Rup dialects. Most other phonological and morphological characteristics of the Subbalkan dialect are the same as the general features typical for all Balkan dialects, cf. article.
