 The Nestram-Kostenar dialect shares strong similarities with the adjacent Kostur (Kastoria) and Korča/Gorica (Korçë) areas.Vidoeski (1991) classifies these dialects as members of a south-western subgroup of the southern group of Macedonian dialects.Stoykov (1962) in his work on Bulgarian dialectology describes them as subgroups of the Kostur dialect.
