About 100 contexts denoting non-verbal expressions of emotions have been considered. In non-verbal communication, signals and symbols are used instead of words, such as facial expressions, gestures, tone, gaze direction, body position, timbre of speech, distance. The analysis of nonverbal behavior includes the observation of these components, as well as the use of methods such as component and contextual analysis. The purpose of the study is to determine the specifics of the lexical transmission of nonverbal emotional signs in A. P. Chekhov's late prose. Materials and methods: the late prose works of A. P. Chekhov were used as the research material. The article identifies specific linguistic and stylistic markers characterizing the author's approach to depicting the emotional sphere. Research results, discussions: in the works of A. P. Chekhov, the means of indicating the non-verbal manifestation of emotions are clearly visible, which is expressed most vividly in the form of hand gestures. Contextual details, dialogues and pauses, and internal monologues of the characters are also important.

Non-verbal communication allows the reader to gain a deeper understanding of the inner world and experiences of the characters in Chekhov's works.
