This chapter addresses the question of how communicating individuals identify themselves linguistically and culturally through ongoing dialogues with other individuals as members of discursive communities. Identity is depicted, in static and dynamic terms, as the uniqueness of the individual, who controls their behavior under social pressure, finding expression in verbal and nonverbal acts of understanding. It is argued that the sense of social identification develops in dyadic inter- and intrapersonal communication, where the communicating individual commits to the distinctiveness of one or more groups, and thus cultures. Regarding the dialogical nature of human communication, the individual as a self is examined as engaged in intertextual relationships, depending on various domains of the reality of everyday life, either through face-to-face interactions or multimodal encounters.
