Vorobets O. Prepositional Substantival Complex in the Semantic and Syntactic Structure of the Sentence

The dissertation explores the functions of the prepositional substantival complex in the semantic and syntactic sentence structure. Complex research of the Ukrainian sentences with prepositional substantival complex from the perspective of semantic syntax has been undertaken, determined by the ambiguous approach to the above mentioned sentences in the modern Ukrainian language and unclear definition of semantic syntactic modifications. The functional semantic potential of the prepositional substantival complex in the sentence structure of the complex, particularly dual-core predicate system, has been considered. The linguistic status of prepositional substantival complex has been explored; the preposition as a formal parameter of the semantic relations expression has been characterized; functional and semantic parameters of the prepositional substantival complex with the objective and instrumental meaning have been defined; semantic and syntactic modification of the prepositional substantival complex with causal, temporal and locative connotations has been analyzed in the thesis. The research shows that the prepositional substantival complex in the semantic syntactic sentence structure is one of the key components and can often be a complicator of its model. The thesis is an open source of information that gives an opportunity for the further research of syntax-semantics interface.
