In the mid-1960s, several new interdisciplinary fields emerged related to the study of discourse, including semiotics, psycholinguistics, sociolinguistics, and pragmatics. These fields studied language use beyond isolated sentences and focused on properties of natural language use. They examined discourse from the perspectives of anthropology, linguistics, formal grammar, pragmatics, semiotics, conversation analysis, and sociolinguistics. Despite different backgrounds, these new fields shared a common interest in studying real language use rather than abstract language.
