In this paper, the destructive emotion of anger is considered through the prism of Korean idioms. The research is aimed at identifying the semantic features of idioms, various aspects of their use and the conceptual metaphors they use. The main focus is on how physiological reactions to anger are reflected in language, as well as how cultural contexts influence the understanding of these idioms, as well as how linguistic features of the Korean language shape the perception and expression of anger in society. The subject of the study is the destructive emotion of anger and its reflection in Korean idioms, as well as cultural and social aspects that influence the formation of these expressions. The destructive emotion of anger is a complex psychological condition that can have a significant impact on human behavior and interaction with others. It is important to note that anger not only affects individual feelings, but also affects cultural norms and linguistic expressions, including idioms.Research methodology: The study uses a qualitative analysis of idiomatic expressions related to anger using a comparative method. The lexical composition and semantics of idioms, as well as their cultural context, are analyzed. The content analysis method is also used to identify common themes and patterns in the use of idioms. The novelty of the research: The work is the first comprehensive study of the destructive emotion of anger in Korean idioms, which allows us to identify unique aspects of Korean culture and language. The study also establishes parallels between Korean and Russian idioms, which contributes to a deeper understanding of the universality and specificity of metaphorical perception of emotions. Conclusions: The results of the study show that Korean idioms associated with anger not only reflect emotional states, but also serve as indicators of social norms and values. The revealed metaphors emphasize the importance of context in the interpretation of emotions and indicate the need to take into account cultural differences in the study of linguistic expressions. The research opens up new horizons for further study of the influence of language on emotional perception in different cultures.
