The Kostur dialect (Macedonian: Костурски дијалект, Kosturski dijalekt) is a member of the Southwestern subgroup of the Southeastern group of dialects of the Macedonian language.[1] This dialect is mainly spoken in and around the town of Kastoria, known locally in Macedonian as Kostur, and in the surrounding Korešta region, (Macedonian: Корешта; in the Kostur dialect: Korèshcha/Корèшча) which encompasses most of the area to the northwest of the town. The Kostur dialect is also partially spoken in Albania, most notably in Bilisht and the village of Vërnik (Vrabnik).[2] The dialect is partially preserved among the ″people of Bulgarian origin in Mustafapaşa and Cemilköy, Turkey, descending from the village of Agios Antonios (Zhèrveni) in Kostur region (Aegean Macedonia)″.[3]
