Several approaches to the interpretation of emotion in poetic text are considered in the article — linguistic, traditional literary and emotive (from the point of modern interdisciplinary interpretation of the phenomenon of emotionality). The relevance of the study determines the belief that, without taking into account of achievements of linguistic emotion and traditional linguistics, the analysis of the stylistic individuality of the writer will be incomplete. Novelty of the study is the introduction concepts of poetic emotion and emotivity into the conceptual apparatus of the style of the text. The subject of study — the emotivity of a poetic text — is defined as a formal-stylistic index / factor of author’s individuality, expressed through the images of a work. The relation of emotional and rational in methods of author’s self-expression, coordination of pathos and emotions is considered. The methodology of the research is determined by an interdisciplinary approach, it is determined during the analysis that among the linguistic approaches the most effective for literary analysis is the method of in-depth study of the category of emotivity in the text, worked out by O. Filimonova. As a result of research an emotivity of the form and content components are interpreted as the interconnected stylistic means in recognition of the lyrical work. It is proved that the expressiveness and aesthetic origin of poetry as a kind of artistic creation predetermines the emotivity of all its components. The basis of the theory of the emotivity of a poetic work, which incorporates the concepts of traditional poetry and prosody, is the principle of revealing poetic emotion in the text in three planes: content, expression and image. Stylistic differentiation of emotive means is conditioned by the formal expression of them at all levels of language use — phonological, morphological, lexical-semantic, phraseological, syntactic levels of structural models of works. According to the results of studying various aspects of the author’s emotionality in the poetic text, it is planned to develop a literary theory of poetic emotion and its description in the historical perspective.
