G.Z. SHKLYAR AND KOSTROMA DIALECTOLOGY AS PART OF THE SCIENTIST’S SLAVIC ACTIVITY

The article defines the role of G.Z. Shklyar, a Belarusian and Russian scientist of the mid-twentieth century, who laid the foundation for a systematic scientific study of dialects of the Kostroma region. His scientific and methodological activities during his work at the Kostroma Pedagogical Institute in the 1940s and 1960s are reviewed: the organization of dialectological expeditions and the collection of materials for the Dialectological atlas of the Russian language, the formation of a card index of the Kostroma regional dictionary, the creation of scientific works, etc. His works help to understand the Kostroma dialects as an integral but complex system and highlight their place in the dialectal division of the Russian language and, more broadly, in Slavic dialects. Studying the features of the phonetic and grammatical structure, the lexical composition of the dialects of the Kostroma region, that is, dealing with the problem of the internal division of the Kostroma dialects, G.Z. Shklyar differentiates them into western and eastern ones, the originality of which is due to their different origins. He emphasizes the territory where people pronounce unstressed «o» as «a», later received the name of the Kostroma (Chukhloma) island where they say «a». The program Slavic works about Belarusian-Polish dictionary relations and the use of vocative form as a means of expressing address in the modern Belarusian language are important for understanding the role of the dialectal environment in the formation of the main features of the lexical structure of Slavic languages and the fate of their ancient grammatical categories in the literary language.
