The article is devoted to the role of statements with the meaning of conditionality in the creation of the conceptual sphere of a literary work. The relevance of the study is determined by the attention of modern philological science to the essence of the individual author’s concept, as well as the growing interest of linguists in the text functions of language units. The material of the study was K. Simonov’s trilogy “The Living and the Dead,” in which syntactic constructions with conjunctions of conditionality group are the dominant linguistic means. It is hypothesized that conjunctions that provide links meaningful for the overall content of the text are actively involved in the construction of key artistic meanings. The components of the artistic concept of WAR, modeled on the basis of statements with conjunctions if and though , are presented. It is shown that constructions with relations of conditionality participate in the formation of conceptual and emotional components of the artistic concept of WAR. The study contributes to the expansion of ideas about the functions of functional parts of speech and helps to present the prospect of their further study in the textual aspect.
