Maleševo-Pirin dialect
The term Maleševo-Pirin or Maleshevo-Pirin or Pirin-Maleshevo dialect is used in South Slavic linguistics to refer to a group of related varieties that are spoken on both sides of the border of Bulgaria and the Republic of North Macedonia. Some linguists treat them as dialects of the Bulgarian language, while Victor Friedman views them as part of Macedonian. According to some authors, they are linguistically transitional between the two national languages, Bulgarian and Macedonian and form part of the larger dialect continuum between them. The dialect group is named after the mountain ranges of Pirin in Bulgaria and Maleševo in Macedonia. When referring specifically to the dialects on the Bulgarian side, the term Petrich-Blagoevgrad dialect, after the two major towns in the area, is also used.
