The reconstruction of synonymous relations in the Proto-Slavic vocabulary based on the Serbo-Croatian dialect material

The paper deals with the analysis of synonymous words of Protoslavic origin that distinguish different Serbo-Croatian dialects (the lexemes are excerpted from The Questionnaire for the Serbo-Croatian Dialectological Atlas). Some of these lexemes have strict geolinguistic characteristics and are connected with certain areas, which allows for the assumption that they performed the same differential function in the Proto-Slavic language. The areas of the other lexemes are often diffuse, and sometimes synonyms of this type co-exist in the same dialect. Therefore, we can assume that these words may have been synonyms found in the same lexical system in Proto-Slavic as well. Most synonyms were created by semantic or lexical innovations that replaced archaisms, while the rest probably consist of parallel creations.
