The article is devoted to a theoretical study of the verbalization of the emotion of joy through the concept of “laughter.” The lexical-semantic, pragmatic, and cultural aspects of laughter as a linguistic expression of joy are examined. The functions of laughter in communication, its semantic multilayered nature, and its role in constructing cultural-emotional experience are analyzed. It is concluded that the concept of “laughter” is a complex lexical-semantic and pragmatic unit performing expressive, communicative, and symbolic functions.
