Erkech dialect
The Erkech dialect is a Bulgarian dialect, which is part of the Balkan group of the Eastern Bulgarian dialects. It originates from two villages in the eastern parts of the Balkan Mountains, Kozichino (formerly Erkech) near Pomorie and Golitsa south of Varna. 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 established numerous colonies in the regions of Provadia, Varna, Novi Pazar, Balchik, Silistra and Pomorie, thus significantly expanding the range of the dialect. The most significant feature of the  dialect, as in all Balkan dialects, is the pronunciation of Old Church Slavonic ѣ (yat) as or , depending on the character of the following syllable.
