Abstract: The article analyzes the structure and features of the lexico-semantic field (of the word) "sanction" in the Russian political sphere; author discuss the semantic connections of its lexical units and metaphorical models of this word in the political discourse of the Russian language. The subject of the study is the semantic content of the term under consideration, presented on the website Kremlin.ru and in the Russian National Corpus. The purpose of the study is to analyze a fragment of the Russian political picture of the world reflected in this field. To achieve this goal, a set of the following linguistic methods has been applied, such as statistical description, component analysis, field method, etc. The novelty of the study lies in the fact that, using the example of the term "sanction", an attempt is made for the first time to build a lexical-semantic field of a political term of the Russian language. The results obtained show that the lexico-semantic field "sanction" in the Russian political sphere consists of 7 microfields that are interconnected with each other and have their own model - "core-periphery", however, the boundary of the transition from the core to the periphery is not clearly traced. In addition, the lexico-semantic field is also a way of representing the language world picture, because the cultural features of the language of any nation are primarily reflected at the level of the lexicon - the most dynamic tier of the language system. The term "sanction" in modern Russian language is used not only in the legal, but also in the political spheres, and is also used as a tool for regulating relations between states and international organizations. In the Russian political sphere, lexico-semantic field "sanction" is accompanied by a large number of metaphors used to reveal the conflicting nature of the sanction and the dramatic nature of political life, the semantics and scope of the term, as well as stylistic evaluation, are expanded.
