Yastremska T. Lexical-semantic modelling of the Ukrainian dialectal space.

Being a comprehensive study, the thesis presents the lexical-semantic modelling of the Ukrainian dialectal space on the example of the concepts TOP/BOTTOM. Lexical-semantic modelling of the dialectal phenomena, their typology, and methods of interpretation was suggested. Methodology and the algorithm of the research of the concepts on the dialectal material, as well as principles of the categorization of the linguistic worldview and highlighting of the semantic field, were improved. The importance of the lexical-semantic modelling not only for the analysis of the derivational and semantic processes but also for the representation of the cognitive space (the result of which is the modelling of the dialectical worldview) was justified. Structural-semantic units were analyzed on the basis of the nominative field of the concepts – base words верх, гора (“top”); низ, діл, під (“bottom”) and their derivatives – that is concluded on dialectal materials. A lexicon of the different parts of speech was presented systematically, phonetic and grammar dialectal features were fixed, and the models of the structural-semantic attitudes were outlined. The main directions of the semantic development and the mechanisms of the semantic changes were detached, and their functioning in dialectal texts and communicative situations was demonstrated. The thesis is also focused on the diachronic aspect of the derivational cluster’s formation that lets us find out the specificity of the semantic creation and the lexeme’s motivation. One of the most controversial problems in the derivation, the problem of multiple motivation of the dialectal words is actualized.
