The Ser-Drama-Lagadin-Nevrokop dialect is a dialect currently treated both in the contexts of the southeastern group of Bulgarian dialects and the southeastern subgroup of dialects of the Macedonian language.Prior to the codification of Standard Macedonian in 1945, the dialects of Macedonia were classified as Bulgarian.The dialect is dynamic and is well known for the shortening of the words, and also characterised by the excessive use of /ʲa/ for the Proto-Slavic yat even in cases where Standard Bulgarian has /ɛ/, a feature which is typical for a number of dialects spoken in southern and southwestern Bulgaria (e.g. the Thracian dialect).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.
