Discourse analysis is the study of language beyond the sentence: how texts (spoken and written) are structured, how meaning is constructed through context, and how speakers and writers achieve their communicative purposes. It asks not "Is this sentence grammatically correct?" but "How does this text work? Why is it organized this way? What is the speaker/writer doing?"
Spoken discourse: how conversations are structured through turn-taking, adjacency pairs (question → answer, greeting → greeting), repair strategies, topic management, and back-channelling. Conversation analysis (Sacks, Schegloff & Jefferson 1974) revealed that spoken interaction follows systematic, rule-governed patterns that are not random or chaotic.
Written discourse: how texts are organized through genre conventions, cohesive devices, thematic progression (how topics develop across sentences), and information structure (given vs. new information). Written discourse analysis draws heavily on systemic functional linguistics (Halliday) and text linguistics.
Pragmatics: how context shapes meaning. Discourse analysis considers speech acts (Austin, Searle), implicature (Grice), politeness strategies (Brown & Levinson), and presupposition. Understanding pragmatics explains why "Can you pass the salt?" is a request, not a question about ability.
Critical discourse analysis (CDA): how language constructs and reinforces power relations, ideologies, and social identities (Fairclough, van Dijk). While less directly applied in general ELT, CDA informs materials evaluation and the analysis of media texts.
Sentence-level grammar teaching alone does not produce learners who can read, write, speak, or listen effectively. Discourse analysis provides the tools to teach at text level:
Discourse analysis connects to Register (how situational variables shape language), Cohesion and Coherence (how texts hold together), Genre (how text types are conventionally structured), and Discourse Markers (the signposting devices that organise both spoken and written discourse).
