The current paper presents an overview of interpersonal conflicts in discourse area of character in modern English fiction discourse from the standpoint of multimodality theory, pragmalinguistics, and semiotics. In this respect semiosis is defined as the action of a sign, a dynamic process of meaning-making and meaning-interpretation realized through multimodal semiotic modes which collectively construct the meaning, communicated in these situations. This constructing is proceeded with the help of conflictives as emergent discursive constructs, the result of interactive constructing by means of verbal, nonverbal and graphic semiotic resources functioning in different stages of conflict communicative process. The linguosemiotic space of their realization is in the plane of disharmony of interpersonal relations of characters and its semiosis is built on cognitive, semiotic, communicative, and pragmatic specifics of conflictives as operational units of conflict discourse. Moreover, the appropriate inferences require understanding of cognitive, psychological, social, and cultural aspects accompanying narration.The aim of the study is also to establish a link between different approaches to the interpretation of conflict communication development and methods of their research in modern scientific studies. Multimodal nature of conflictives comprises several modes of multimodality for the analysis of conflict semiosis in fiction discourse: verbal, nonverbal, visual, auditory, kinetic etc. These patterns of meaning combination or meaning multiplication through different semiotic modes together construct the meaning, communicated and interpreted in the situations of interpersonal conflicts in discourse area of character in modern English fiction discourse. To achieve the objectives of research, a semiotic approach to the paradigm of conflict discourse approaches is applied, together with the elements of conversational analysis, multimodal discourse analysis, pragmatic analysis. The obtained results show the capacity of the semiotic approach to the conflict studies to enhance the effectiveness of linguistic research in the field of conflict studies.
