Arvanites are a centuries-old local Albanian-speaking Greek community, their language is now in danger of extinction and Slavic Macedonian is also spoken in in Greece.
Arvanitika (/rvntk/; Arvanitika: b, romanized: arberisht; Greek: , romanized: arvanitika), also known as Arvanitic, is the variety of Albanian traditionally spoken by the Arvanites, a population group in Greece. Arvanitika is today endangered, as its speakers have been shifting to the use of Greek and most younger members of the community no longer speak it. Arvanites (/rvnats/; Greek: , romanized: Arvanites; Arvanitika: b, romanized: Arbereshe or b, romanized: Arberore) are a bilingual population group in Greece who traditionally speak Arvanitika, an Albanian language variety, along with Greek. They settled in southern Greece during the late Middle Ages and were the dominant population element in parts of the Peloponnese, Attica and Boeotia until the 19th century. Macedonian (/msdonin/;  , translit. makedonski jazik, pronounced [makdnski jazik (listen)) is an Eastern South Slavic language. The exact number of speakers of Macedonian in Greece is difficult to ascertain due to the country's policies. Estimates of Slavophones ranging anywhere between 50,000 and 300,000 in the last decade of the 20th century have been reported.
