Interpersonal communication is the process through which individuals exchange and interpret verbal, nonverbal, and symbolic messages within a social relationship context to create shared meaning, regulate interactions, and establish patterns of mutual understanding. It encompasses the transmission and reception of information between two or more people, involving communicative behaviors such as language use, gestures, facial expressions, emotional expressions, and contextual interpretation [1]. Within language and communication studies, interpersonal communication is distinguished from intrapersonal communication, which occurs within an individual’s cognitive processes, and from mass communication, which involves mediated messages directed toward large and relatively dispersed audiences [2]. The concept includes both intentional and unintentional message exchanges, as communication participants continuously construct meaning through linguistic choices, relational cues, and situational factors [3]. Interpersonal communication is therefore defined by its interactive, relational, and context-dependent nature, in which communicative acts are shaped by the participants’ perceptions, social roles, and shared communicative environment.
