The Northwestern Bulgarian dialects are two closely related dialects of the Bulgarian language, which are located west of the yat boundary and thus are part of the Western Bulgarian dialects. The range of the dialects includes most of northwestern Bulgaria, to the west of the line between Nikopol, Pleven and Mezdra and to the north of the line between Vratsa and Belogradchik. They bear strong resemblance to their neighbouring Eastern Bulgarian dialects and with some exceptions, mainly the pronunciation of yat, have the same phonological and morphological features as the neighbouring subdialects of the Eastern Bulgarian Central Balkan dialect.
The Byala Slatina-Pleven dialect is a Bulgarian dialect spoken in the regions of Pleven, Byala Slatina and Kula in northwestern Bulgaria. The dialect is part of the Northwestern Bulgarian dialects. The most significant feature of the dialect, as in all Western Bulgarian dialects, is the pronunciation of Old Church Slavonic ѣ (yat) only as instead of formal and Eastern Bulgarian я/е (~) – бел/бели instead of бял/бели. Otherwise, the Byala Slatina-Pleven dialect bears strong resemblance to its neighbouring Eastern Bulgarian dialects and with some exceptions, mainly the pronunciation of yat, has the same phonological and morphological features as the neighbouring subdialects of the Eastern Bulgarian Central Balkan dialect.
The Balkan dialects are the most extensive group of dialects of the Bulgarian language, covering almost half of the present-day territory of Bulgaria and slightly less than a third of the territory on the Balkans where Bulgarian is spoken. Their range includes north-central Bulgaria and most of the Bulgarian part of Thrace, excluding the Rhodopes, the region of Haskovo and Strandzha. As a result of the mass population movements that affected eastern Bulgaria during the 19th and the beginning of the 20th century, the Balkan dialects are now spoken also in vast areas of northeastern Bulgaria, especially the regions of Dobrich and Varna. The most significant feature of the dialects, as in most Eastern Bulgarian dialects, is the pronunciation of Old Church Slavonic ѣ (yat) as or, depending on the character of the following syllable. The Balkan dialects, and in particular, the Central Balkan dialect, lie at the foundation of formal Bulgarian. However, they are not identical to the standard language because many of its features derive from the Western Bulgarian dialects, including the Macedonian dialects, or are a compromise between Eastern and Western standard.
The Central Balkan dialect is a Bulgarian dialect that is part of the Balkan group of the Eastern Bulgarian dialects. Its range includes most of north-central Bulgaria, as well as the regions of Karlovo, Kazanlak and Plovdiv in southern Bulgaria, all the way down to the northernmost ridges of the Rhodopes. As a result of the mass population movements that affected eastern Bulgaria during the 19th and the beginning of the 20th century, the Central Balkan dialect is now spoken also in vast areas of northeastern Bulgaria. The most significant feature of the dialect is the pronunciation of Old Church Slavonic ѣ (yat) as or, depending on the character of the following syllable. The Central Balkan dialect lies at the foundation of formal Bulgarian. However, it is not identical to the standard language because many of its features derive from the Western Bulgarian dialects, including the Macedonian dialects, or are a compromise between Eastern and Western standard. The Central Balkan dialect includes a number of subdialects, e.g. Troyan, Lovech, Gabrovo, Karlovo, Kalofer, Tryavna, etc. which share many common features and yet have some differences.
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 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.
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 or, depending on the character of the following syllable.
The Pirdop dialect is a Bulgarian dialect, which is part of the Balkan group of the Eastern Bulgarian dialects. Its range includes the towns of Pirdop, Zlatitsa and Koprivshtitsa, as well as several neighbouring villages. 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. However, the Pirdop dialect also features a number of characteristics which bring it closer to the neighbouring Western Bulgarian dialects, and especially to the Botevgrad dialect and which, in turn, separate it from the rest of the Balkan dialects.
The Rup dialects, or the Southeastern dialects, are a group of Bulgarian dialects located east of the yat boundary, thus being part of the Eastern Bulgarian dialects. The range of the Rup dialects includes the southern part of Thrace, i.e. Strandzha, the region of Haskovo, the Rhodopes and the eastern half of Pirin Macedonia.
The Smolyan dialect or Central Rhodope dialect is a Bulgarian dialect of the Rhodopean group of the Rup dialects. Its range includes most of the Central Rhodopes, i.e. the region of Smolyan. Its immediate neighbours are the Rhodopean Hvoyna dialect to the north, the Serres-Nevrokop dialect and the Razlog dialect to the west and the Turkish dialects of the Turkish population in the Eastern Rhodopes. To the south, the Smolyan dialect crosses the Greek-Bulgarian border and is spoken by much of the Muslim Bulgarian (Pomak) population in Western Thrace. As a result of the rugged mountainous terrain and the century-long isolation of the region from the rest of the country, the Smolyan dialect is the most idiosyncratic of all Bulgarian dialects and is not readily understandable even for its immediate neighbours.
The Hvoyna dialect is a Bulgarian dialect of the Rhodopean group of the Rup dialects. Its range includes the northern part of the Central Rhodopes and the town of Batak in the Western Rhodopes. Its immediate neighbours are the Central Balkan dialect to the north, the Smolyan dialect to the south and the Rhodopean Chepino dialect to the west.
The Chepino dialect is a Bulgarian dialect of the Rhodopean group of the Rup dialects. Its range includes the northwestern Rhodopes, i.e. the towns of Velingrad, Rakitovo and Kostandovo and the villages of Dragichevo and Dorkovo. Its immediate neighbours are the Central Balkan dialect and the Ihtiman dialect to the north, the Babyak dialect to the west and south and the Hvoyna dialect to the east. The Chepino dialect is spoken by both Orthodox and Muslim Bulgarians in the region irrespective of religious affiliation.
The Paulician dialect is a Bulgarian dialect of the Rhodopean group of the Rup dialects. The Paulician dialect is spoken by some 40,000 people, nearly all of them Catholic Bulgarians, in the region of Rakovski in southern Bulgaria and Svishtov in northern Bulgaria, aswell as regions in Romania. The language of the Banat Bulgarians, late 17th century Bulgarian Catholic migrants to Banat, is phonologically and morphologically identical to the Paulician dialect.
The Babyak dialect is a Bulgarian dialect, member of the Rup or Southeastern Bulgarian dialects. It is spoken in several mountainous villages on the western fringes of the Rhodopes and is thus sandwiched between the Chepino dialect on the east and northeast and the Razlog dialect to the south and west. It shares a number of phonological characteristics with both the Rup and the Southwestern dialects. Because of its specific reflexes of Old Church Slavonic yat, it is generally classified as a Rup dialect but is actually transitional between the two dialectal groups.
The Razlog dialect is a Bulgarian dialect, member of the Rup dialects. Its range includes the valley of Razlog in southwestern Bulgaria and its immediate neighbours are the Rup Serres-Nevrokop dialect to the south, the Babyak dialect to the east, the Samokov and Ihtiman dialects to the north and the Blagoevgrad-Petrich dialect to the west. It shares a number of phonological characteristics with both the Rup and the Southwestern dialects.
The Teteven dialect is a Bulgarian dialect, which is part of the Balkan group of the Eastern Bulgarian dialects. It is spoken in the town of Teteven and several neighbouring villages and is almost completely surrounded by the Central Balkan dialect, except on the west where it borders on the Western Bulgarian Botevgrad 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.
The Southwestern Bulgarian dialects are a group of Bulgarian dialects which are located west of the yat boundary and are part of the Western Bulgarian dialects. The range of the Southwestern dialects on the territory of Bulgaria includes most of west central and southwestern Bulgaria. The Southwestern dialects border on the Northwestern dialects to the north, the Transitional dialects to the northwest and the Balkan dialects and the Rup dialects to the northeast and southeast, respectively. If the Macedonian language is regarded as a third literary form of Modern Bulgarian, then the Southwestern dialects extend west and southwest to include the Slavic dialects in Vardar Macedonia and the western half of Greek Macedonia. Should the Macedonian language be counted as a separate language, then the southernmost dialect of the group, the Blagoevgrad-Petrich or Pirin dialect, along with the corresponding variety on the Macedonian side of the border, the Maleshevo dialect, constitute a transitional dialect between Bulgarian and Macedonian. A defining characteristic of the Southwestern dialects is the gradual transition from one dialect to another, as well as to dialects which belong to other dialectal groups. For example, the Dupnitsa dialect is transitional to both the Samokov dialect and the Blagoevgrad-Petrich dialect, the Botevgrad dialect is transitional to the Eastern Bulgarian Balkan dialects, and especially to the Pirdop dialect, etc. etc.
The Botevgrad dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in the region of Botevgrad and Etropole in northwestern Bulgaria. It is located on the yat boundary and is closely related to the Eastern Bulgarian Pirdop dialect.
The Ihtiman dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in the regions of Ihtiman, Kostenets and Septemvri in central western Bulgaria. It is transitional between the Botevgrad and Samokov dialect.
The Samokov dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in the region of Samokov in central western Bulgaria. Its immediate neighbours are the Sofia dialect and Elin Pelin dialect to the north, the Ihtiman dialect to the east, the Dupnitsa dialect to the west and the Razlog dialect to the south.
The Shumen dialect is a Bulgarian dialect, member of the Moesian dialects. It is one of the best preserved Moesian dialects and is spoken in the regions of Shumen and Kaspichan.
