The limitless semantic potencies of communication is within the framework of the language conventional semantics, which imposes a number of restrictions, including on the explication of emotional experiences by the speaker. The latter either chooses a read y-made preset formula, or directs communicative efforts to search for and objectify emotional and semantic shades of meaning with an uncodified form of verbalization. If the form of expression of an emotional experience is new, atypical, unconventional, we should talk about the representation of diffuse emotive semantics, approaching the actual emotional experience. Diffusivity (fuzziness, vagueness, multiple inconsistencies, ambiguity) is an immanent property of semantics that corresponds to both the natur e of the sign and the environment in which the sign acts. The assumption is that, depending on the characteristics of the discourse and the genre characteristics of the elements included in it, artistic communication was considered. The author of a work of art must go beyond the linguistic prescription, which allows him to have the desired effect on the addressee. The analysis of a dramatic work shows a variety of forms of explication of diffuse emotivity, when emotional experiences become a discursive and genre-forming category: the expression of complex vague emotions allows creating an image of a multifaceted and interesting character. The texts of modern plays allow tracing a similar trend towards diversifying the form of expression of diffuse emotivity, but the emotional tonality is less diverse: negative emotional experiences set the emotional dominant, therefore, the ‘consolidation’ of the emotive occurs rather than through the vector of mixing positive and negative assessments, but the intensification and concretization of the negative evaluative component. The author also postulates that language always approximately describes emotions, but in artistic communication such approximativeness is expressed in conscious and creative imitation, which transforms and develops the linguistic norm.
