Melnyk I. The transposition of part-of-speech classes in verb in modern Ukrainian literary language.

The dissertation deals with the investigation of syntactic and morphological transferring of lexico-grammatical words' classes in verb. The conceptual bases of part-of-speech transposition's study are substantiated. The classification model of transposition of four main parts of speech in verb was established, it's forms and degrees of manifestation were ranked. Specialized and non-specialized analytical tools because of their grammatical and semantic specifics were characterized in details, possibility / impossibility of combination with whole conceptual kinds of syntactically verbalized units were also analysed. The degrees of derivational affixes' productivity as the means of verbal morphologization of syntactic transpozyts were determined. The transpositional potential and the semantic specificity of syntactically verbalized forms according to their valence actantial derivation and the degrees of predicative binding were analysed. According to new theoretical basis of functional-categorical grammar the peculiarities of function of all kinds of verbal syntactic and morphological transpozyts in formal-syntactic and semantic-syntactic structure of simple elementary and complicated sentence structures were established.
