The Ser-Drama-Lagadin-Nevrokop dialect is closely related to the neighbouring dialects. It is closer to all Eastern Bulgarian dialects than to all Western.Стойков, Стойко. Българска диалектология, София 2002, с. 170–186 Macedonian shares much less features with the dialect than it does with the Maleševo-Pirin dialect of Macedonianstr. 249- 252 Makedonski jazik za srednoto obrazovanie- S. Bojkovska, D. Pandev, L. Minova-Ǵurkova, Ž. Cvetkovski- Prosvetno delo AD- Skopje 2001The Sociolinguistics of Literary Macedonian, Victor A. Friedman, The University of Chicago and Bulgarian. Some Bulgarian dialects are more similar to Macedonian than the Ser-Nevrokop dialect, the Samokov dialect shares more features with Macedonian than both the Ser-Nevrokop and the Pirin-Malasevo dialects do, even though it is not considered a Macedonian dialect, the most of the western Bulgarian dialects and the Smolyan dialect share more similarities with Macedonian than the Ser dialect does. The Samokov dialect, most remarkably, shares with Macedonian and the Maleševo-Pirin dialect—the "to be" verb for future tense—"ke, which in contrast is "shte in the Ser-Nevrokop dialect and in the Bulgarian language. The Yat border passes through the Maleševo-Pirin dialect and divides it on such a way that in the northern area of the dialect the yat is pronounced "e (as in all the Western Bulgarian dialects and Macedonian) and in the south—"ya (as in the Eastern Bulgarian dialects and standard Bulgarian). In the Ser-Nevrokop dialect the yat is pronounced in most places "ya, therefore the city of Serres, after which the dialect is named, is called "Syar by the locals, as opposed to "Ser in Macedonian. The first person singular is as in Bulgarian, ending with "a or "am as opposed to the constant "am in Macedonian and the Bulgarian Smolyan dialect. The words for man -"m'zh and for a dream "s'n are as in Bulgarian, unlike the Macedonian "mazh and "son. The words for night and tear—"nosht and "s'lza are as the Bulgarian, unlike the Macedonian "nok and "solza.
