Aim. To identify the lexical and semantic means involved in the creation of speech aggression in the television discourse; to identify the frequency and peripheral components of the lexical system of speech aggression in the genre of talk shows and to conduct a detailed analysis of frequent and less frequent lexemes; to draw conclusions about the use of words in speech aggression. Methodology. Methods of research of dictionary definitions and lexicographic litters, stylistic analysis, and field modeling served to achieve the goal. Statistical processing of the studied language material was also used. The material is lexical and semantic means that express speech aggression, selected from the speeches of the talk show participants. Results. The analysis showed that the frequency constituents of the lexical system of speech aggression in the genre of talk shows are evaluative, colloquial, colloquial vocabulary, jargon, negatively colored phraseological units. The near-frequency zone includes expletive language (invective) and metaphor. The periphery of this system includes occasional words, foreign language vocabulary, proper names. Aggressive speech acts of the talk show genre are characterized by an emotional, explicit assessment. The type of jargon that prevails in an aggressive speech in TV debates is general jargon (which is based on criminal jargon). The intention to insult or humiliate the addressee of the speech or a third person is manifested in different degrees in invective and rough-colloquial vocabulary: the use of colloquial language leads to an increase in the expressiveness of speech, evaluativeness, indicates implicit aggression; invective is specifically used to insult, humiliate the interlocutor. There is a dependence of the composition of the vocabulary of an aggressive utterance on the type of speech act. Research implications. . The obtained research results can be used in university special courses on the theory and practice of speech influence in practical classes on the text's analysis and interpretation. The materials can also be used in teaching Russian as a foreign language: in teaching methods of recognizing and interpreting aggression in speech communication.
