The Slavic dialects of Greece are the Eastern South Slavic dialects of Macedonian and Bulgarian spoken by minority groups in the regions of Macedonia and Thrace in northern Greece. Usually, dialects in Thrace are classified as Bulgarian, while the dialects in Macedonia are classified as Macedonian, with the exception of some eastern dialects which can also be classified as Bulgarian. Before World War II, most linguists considered all of these dialects to be Bulgarian dialects. However, other linguists opposed this view and considered Macedonian dialects as comprising an independent language distinct from both Bulgarian and Serbo-Croatian.
Slavic dialects spoken in the region of Greek Macedonia
The continuum of Macedonian and Bulgarian is spoken today in the prefectures of Florina and Pella, and to a lesser extent in Kastoria, Imathia, Kilkis, Thessaloniki, Serres and Drama.
According to Riki van Boeschoten, the Slavic dialects of Greek Macedonia are divided into three main dialects (Eastern, Central and Western), of which the Eastern dialect is used in the areas of Serres and Drama, and is closest to Bulgarian, the Western dialect is used in Florina and Kastoria, and is closest to Macedonian, the Central dialect is used in the area between Edessa and Salonica and is an intermediate between Macedonian and Bulgarian. Trudgill classifies certain peripheral dialects in the far east of Greek Macedonia as part of the Bulgarian language area and the rest as Macedonian dialects. Victor Friedman considers those Macedonian dialects, particularly those spoken as west as Kilkis, to be transitional to the neighbouring South Slavic language.
Macedonian dialectologists Božidar Vidoeski and Blaže Koneski consider the eastern Macedonian dialects to be transitional to Bulgarian, including the Maleševo-Pirin dialect.
Bulgarian dialectologists claim all dialects and do not recognize the Macedonian. They divide Bulgarian dialects mainly into Eastern and Western by a separating isogloss(dyado, byal/dedo, bel "grandpa, white"(m., sg.)) stretching from Salonica to the meeting point of Iskar and Danube, except for the isolated phenomena of the Korcha dialect as an of Eastern Bulgarian Rup dialects in the western fringes.
The nasal vowels are absent in all Slavic dialects except for the dialects of Macedonian in Greece and the Lechitic dialects (Polabian, Slovincian, Polish and Kashubian). This, along with the preservation of the paroxitonic in the Kostur dialect and Polish, is part of a series of isoglosses shared with the Lechitic dialects, which led to the thesis of a genetic relationship between Proto-Bulgarian and Proto-Macedonian with Proto-Polish and Proto-Kashubian.
The Old Church Slavonic language, the earliest recorded Slavic language, was based on the Salonica dialects. Church Slavonic, long-used as a state language further north in East and West Slavic states and as the only one in Wallachia and Moldavia until the 18th century, influenced other Slavic languages on all levels, including morphonology and vocabulary. 70% of Church Slavonic words are common to all Slavic languages, the influence of Church Slavonic is especially pronounced in Russian, which today consists of mixed native and Church Slavonic vocabulary.
Fringe views
A series of ethnological and pseudo-linguistic works were published by three Greek teachers, notably Boukouvalas and Tsioulkas, whose publications demonstrate common ideological and methodological similarities. They published etymological lists tracing every single Slavic word to Ancient Greek with fictional correlations, and they were ignorant of the dialects and the Slavic languages entirely. Among them, Boukouvalas promoted an enormous influence of the Greek language on a Bulgarian idiom and a discussion about their probable Greek descent. Tsioulkas followed him by publishing a large book, where he "proved" through an "etymological" approach, that these idioms are a pure Ancient Greek dialect. A publication of the third teacher followed, Giorgos Georgiades, who presented the language as a mixture of Greek, Turkish and other loanwords, but was incapable of defining the dialects as either Greek or Slav.
Serbian dialectology does not usually extend the Serbian dialects to Greek Macedonia, but an unconventional classification has been made by Aleksandar Belić, a convinced Serbian nationalist, who regarded the dialects as Serbian. In his classification he distinguished three categories of dialects in Greek Macedonia: a Serbo-Macedonian dialect, a Bulgaro-Macedonian territory where Serbian is spoken and a Non-Slavic territory.
