What language is spoken in Bulgaria?
Moesian dialects
The Moesian dialects are a group of closely related dialects of the Bulgarian language, part of the Eastern Bulgarian dialects. The Moesian dialects are spoken in northeastern Bulgaria and in the regions of Karnobat, Aytos, Burgas and Yambol in southern Bulgaria. However, due to the mass population movements that affected eastern Bulgaria during the 19th and the beginning of the 20th century, nowadays, there are very few areas where only Moesian is spoken. In most areas, and especially in southern Bulgaria and Dobruja, Moesian speakers are mixed with speakers speaking Balkan dialects. As a result of this and also due to the influence of the literary language, most features of the Moesian dialects have given way to features typical for the Balkan dialects.Стойков, Стойко: Българска диалектология, Акад. изд.
