Dialogue analysis is a research approach dedicated to the systematic examination of spoken or written interaction between individuals. It investigates the structure, function, and dynamics of communicative exchanges, focusing on how participants construct meaning, manage turns, and achieve interactional goals through linguistic and pragmatic means within specific contexts. Key characteristics include the analysis of turn-taking mechanisms, sequential organization, linguistic features, and the interplay between language use and social context. Its significance lies in providing comprehensive insights into human communication, social interaction, power relations, and the construction of understanding across diverse settings and disciplines.
