Claim: Arvanites are a centuries-old local Albanian-speaking Greek community, their language is now in danger of extinction and Macedonian is also spoken in in Greece.
Evidence: Arvanites (/ˈɑːrvənaɪts/; Greek: Αρβανίτες, romanized: Arvanítes; Arvanitika: Αρbε̱ρεσ̈ε̰, romanized: Arbëreshë or Αρbε̰ρορε̱, romanized: Arbërorë) 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. Language attrition is the process of losing a native or first, language. Arvanitika is in a state of attrition due to language shift towards Greek and large-scale internal migration to the cities and subsequent intermingling of the population during the 20th century.
