Variation of syntactic units based on modeling the semantic structure of a sentence in speech communication

Abdukadyrova Tumisha Tashtievna, Sakaeva Mata Vahitovna

The purpose of the article is to understand and scientifically substantiate the study of the variability of syntactic units based on the modeling of propositional semantics of a sentence. The variability of language units at different levels reveals specific features due to changes in the ratio "invariant-variants". In particular, one of the debatable problems is the search for reasons for identifying the invariant. The semantic model of a sentence that reflects its semantic structure is implemented in one or more structural schemes. The author confirms that when searching for reasons for selecting an invariant in the syntax, a comprehensive approach is necessary that takes into account to some extent all components of the sentence's meaning. Thus, when considering the variation in syntax, involving the identification offers both virtual and actual units arising from the implementation of a particular model in the act of verbal communication, it is necessary to take into account a number of semantic, structural-syntactic and text-forming factors, reflecting verbosestatus the nature and terms of the internal and external contexts.
