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,[1][2][3] while Victor Friedman views them as part of Macedonian.
[4] 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.
[7][8] According to Dennis P. Hupchick:Until a modern Macedonian literary language was mandated by the communist-led partisan movement from Macedonia in 1944, most outside observers and linguists agreed with the Bulgarians in considering the vernacular spoken by the Macedonian Slavs as a western dialect of Bulgarian.
In other words, regardless of the structural and linguistic arguments put forth by a majority of Bulgarian dialectologists, as well as by their Macedonian counterparts, they are ignoring one, essential fact – that the present linguistic identities of the speakers themselves in various regions do not always correspond to the prevailing nationalist discourses.The dialect is spoken in the towns of Delčevo, Pehčevo, Berovo and the surrounding villages in the east of the Republic of Macedonia, and in the regions of Blagoevgrad, Petrich and Sandanski in Bulgaria.
