METAPHOR POWER AND THEME-RHEMATIC TEXT STRUCTURE
This article examines the problem of the metaphor speech impact in its relationship with the text structure. The author analyzes theoretical views and approaches in the field of the internal text structure analysis, studying in detail the theme-rhematic hierarchy, which is described as the relationship between hyperthema and rhematic dominant. Based on the theme-rhematic progressions of F. Danes, the author concludes that there are two key types of text structure: parallel and sequential. Detailed steps to identify the internal structure of the text allow to divide the text into blocks corresponding to the theme and rheme, in which specific metaphorical mappings can be distinguished. Theoretical knowledge on the different functional and communicative role of theme and rheme in the structure of the text allows us to determine the difference in the use of metaphors in the text. The metaphor in the theme plays a problem-setting, identification, ontological role, while the metaphor in the rheme is used to rethink the problem, its structuring in the mind. Based on the calculation of metaphors by means of a specially developed index (MStI (in)), which takes into account the number and density of metaphors for different parts of the text, it is possible to draw a conclusion about which of the functions dominates and to what extent. This approach allows the researcher to draw conclusions about the purpose of using the figurative language in any text and thereby analyze the implicit intentional characteristics of the entire text. The index presented in this article will be useful for studying the metaphoricity of texts in which it is difficult to distinguish external compositional elements, as well as texts with a parallel theme-rhematic hierarchy.
