Interactional linguistics (IL) is an interdisciplinary approach togrammar andinteraction in the field oflinguistics, that applies the methods ofConversation Analysis to the study of linguistic structures, includingsyntax,phonetics,morphology, and so on. Interactional linguistics is based on the principle that linguistic structures and uses are formed through interaction and it aims at understanding how languages are shaped through interaction. The approach focuses on temporality, activity implication and embodiment in interaction.[1] Interactional linguistics asks research questions such as "How are linguistic patterns shaped by interaction?" and "How do linguistic patterns themselves shape interaction?".[2]: 78
Interactional linguistics is partly a development withinconversation analysis focusing on linguistic research questions, partly a development of Emergent grammar or West Coast functional grammar. The two approaches can be seen as effectively merged into interactional linguistics,[3] but also withinteractional sociolinguistics.[2]
While conversation analysis did indeed study language since its beginning, it grew out ofsociology and often dealt with sociological research questions and topics. However, over time the use of ideas and methods from conversation analysis for linguistic research questions grew. Some early uses of the termInteractional Linguistics are found in the title of a 1995 conference with the title[4]: 211 and 2000 conferenceInteractional Linguistics: Euro-conference on the Linguistic Organisation of Conversational Activities[5] and in the 2001 bookStudies in Interactional Linguistics[6] byElizabeth Couper-Kuhlen andMargret Selting. They mark a development that most clearly took place in the 90s through the publication of various edited volumes - most importantly the bookInteraction and Grammar edited byElinor Ochs,Emanuel Schegloff andSandra Thompson.[1]
While there is no agreed-upon delineation between the two, interactional linguistics is characterized by looking at linguistic structures and employing linguistic terminology for its description of what interactants orient to (and not only looking at e.g.gesture). It goes against earlier approaches where research was focused on investigating written language. With the improvement of technology, linguists have started to focus on spoken language as well due to its functions in intonation andtranscription system. Though thefunctional linguistic study was not all about conversational interaction, it was really helpful for the language study which saw linguistic form as being useful on the situated occasion of use. The next step which made interactional linguistics develop was the important work on conversation analysis. Some sociologists were saying the study of everyday language was the essence of social order; some other kinds of discourse were said to be understood as habituations of the fundamental conversational order. The termtalk-in-interaction was created as an inclusive term for all of naturally speech exchange.
Emergent grammar was proposed byPaul Hopper and postulates that rules of grammar come about as language is spoken and used. This is contrary to thea priori grammar postulate, the idea that grammar rules exist in the mind before the production of utterances.[7] Compared to the principles ofgenerative grammar and the concept ofUniversal Grammar, interactional linguistics asserts that grammar emerges from social interaction.[8] Whereas Universal Grammar claims that features of grammar are innate,[9] emergent grammar and other interactional theories claim that the human language faculty has no innate grammar and that features of grammar are learned through experience and social interaction.[8]
Interactional linguistics has connections to various linguistic approaches, such asdiscourse analysis andconversation analysis, and is used to investigate the relationship between grammatical structure and real-time interaction and language use.[10] Further, the topic of normativity in a discourse or asocial norm both contribute to how a conversation functions.[11] Interactional linguists contrast their perspectives with that of "traditional structuralist descriptions".[3]: 547 [12]
Scholars in interactional linguistics draw fromfunctional linguistics, conversation analysis, andlinguistic anthropology in order to describe "the way in which language figures in everyday interaction and cognition"[13] and Interactional Linguistics may be considered ausage-based approach to language. Studies in interactional linguistics view linguistic forms, including syntactic and prosodic structures, as greatly affected by interactions among participants in speech,signing, or other language use. The field contrasts with dominant approaches to linguistics during the twentieth century, which tended to focus either on the form of language per se, or on theories of individual language user'slinguistic competence.[6] Various scholars have or are attempting to write grammar books from an interactional linguistic perspective, for languages such asAlto Perené[14] andDanish (SeeSamtalegrammatik.dk).[15]
Interactional linguistics can also be considered compatible withconstruction grammar andcognitive grammar.[16] Wolfgang Imo has coined the termInteractional Construction Grammar on the recognition of similarities between construction grammar and interactional linguistics.[17] Interactional linguistics does not subscribe to the strict separation ofcompetence andperformance ofgenerative grammar. Methodically, it takes what would be considered "performance" as the empirical starting point.[16]
