The Kotel-Elena-Dryanovo dialect is a Bulgarian dialect, which is part of the Balkan group of the Eastern Bulgarian dialects. Its range includes the eastern parts of the Balkan Mountains, i.e. the regions of Dryanovo, Kotel and Elena). 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 dialect have also moved south towards Burgas and north towards Varna and Targovishte. The most significant feature of the dialect, as in all Balkan dialects, is the pronunciation of Old Church Slavonic ѣ (yat) as ʲa or ɛ, depending on the character of the following syllable. The Kotel-Elena-Dryanovo dialect can be divided into three subdialects, i.e. Kotel, Elena and Dryanovo etc. which share many common features and yet have some differences.
