Abstract
One of the most critical problems of the Linguistics of text is the structure study of the literary text, principles of its organization following the rules of the compositions that suggest splitting the linguistic work into the interconnected parts. In this regard, it is necessary to research the individual compositional and significant elements of the text and their role in forming the whole work. The paper focuses on revealing structural and syntactic properties of the author's digressions, namely, detecting such concepts as integration/non-integration of the author's digressions in the English literary prose. Integrated and non-integrated types of author's digressions into the academic space of the text have been distinguished based on interpretative textual and compositional analysis. The analysis of the text-forming function of the author's digression contributed to defining the features of the cohesion of the literary text and included in its elements. The analysis results show that the author's digressions can be both integrated and non-integrated. Non-integration of the author's digression lies in their composition-semantic independence, and integrated author's digressions are the ones that the author weaves into the text with different types of cohesion. This research promotes the studies of the cognitive aspect of the author's digression in the different genres literary texts of English and American prose.
