The article deals with syntactic innovations in the poetry of V. Stus, reveals the communicative and functional essence of the "segmented construction" concept, describes the functions of constructions with nominative of concept and defines the place of segmented constructions with the meaning of theme in the poetry of the author.Background: The poetry system of V. Stus combined various techniques for the creation of stylistically loaded linguistic units, their syntactic modifications, and witnessed the acquirement of new expressive shades, through the direct subordination of the linguistic and aesthetic task. The segmented constructions with nominative of theme is the traditional object of the study of poetry. Innovative processes, which were reflected in poetry, determined the possibility to outline the trends of the development of a new syntax of poetry. New tendencies in the syntax are most pronounced in syntagmatic decomposition, therefore, these constructions with a weakened syntagmatic relation belong to the expressive syntax.Purpose: The process of segmentation, which means the separation of the text into segments, takes place in the modern expressive Ukrainian syntax, therefore the task of our study is to discover the communicative and functional essence of the "segmented construction" concept; to study the poetry of V. Stus at the level of the separated structures of the expressive syntax; to analyze the functions of constructions with nominative of concept in the poetry of V. Stus; to determine the place of segmented constructions with the meaning of theme in the author's poetry.Results: The means of expressive syntax in the poetry of V. Stus are partially and segmented sentences. These are the most effective stylistic techniques that fill the sentence with some expression, emotionality, make it closer to everyday speech, visualize the idea, create a peculiar drawing of the poem. Elements of expression can be distinguished in written speech forms, in which imagery belongs to the defining features and motivates their functional load. Segmented constructions of expressive syntax, namely, constructions with nominative of concept, give a special emotionality to poetry. In the poetry of V. Stus the use of constructions with nominative of concept can be traced. Such syntactic constructions with high accentuation, intonational and semantic concentration, caused by a sharp reduction in the length of the sentence, implement the author's subjective modality, enhance the conceptuality of the author's expression. The constructions with nominative of concept, which V. Stus uses in his work, can characterize the internal state of a person, the names of events, phenomena of nature, etc., the names of persons (by profession, by degree of affiliation, general name of person). The constructions with nominative of concept in poetry of V. Stus perform various functions, among which the introduction of the reader into the philosophical argument of the hero or the author plays an important role. The functioning of such constructions is accompanied by a psychological subtext.Discussion: The syntactic level of the poetry of V. Stus is subordinated to a general artistic orientation to emotionality and expressiveness. The specific content of the poetic image in the context of a broad context is reinterpreted, its semantic and functional structures are expanded due to various emotional and semantic transformations that are enriched in the reader's perception of new, unexpected associations. Focusing on a certain cut-off text of a complex of various stylistic techniques increases significantly the expression of the lyrics of V. Stus, distinguishes the most significant parts of the text and determines its individual stylistic originality. The study of the dynamic processes of segmented constructions, namely, the constructions with nominative of concept, the manifestation of their expressive means in the poetry, is one of the main tasks at the present stage of the development of Ukrainian linguistics, which is the prospect of further research.
