Critical Discourse Analysis — CDA

Discourse analysis describes how language functions in context — how meaning is constructed, how turns are organised, how genres work. CDA adds an explicit critical and normative dimension: it asks whose interests are served by particular discursive choices, how power relations are reproduced or contested through language, and what ideological work texts perform. CDA is politically positioned; it does not claim value-neutrality and takes a stance against discursive forms of domination and injustice.

A working knowledge of linguistics — at minimum an understanding of transitivity, modality, lexical choices, and rhetorical devices — is important for rigorous CDA. Without it, analysis tends to stay at the level of paraphrase. However, most CDA frameworks are designed to be learnable by social scientists, and textbooks by Fairclough, Jorgensen and Phillips, and Wodak provide accessible introductions. Collaborating with a discourse linguist strengthens the analysis considerably.

CDA does not prescribe a corpus size. The goal is depth of analysis rather than breadth of coverage, so a focused corpus of a few key texts is often more analytically productive than a large corpus treated superficially. The guiding principle is theoretical saturation with respect to the research question: enough texts to address the power or ideology question being investigated, selected on theoretical rather than statistical grounds.

Yes. CDA is frequently combined with ethnography (to understand the social context of text production), corpus linguistics (to identify patterns across large datasets that then receive close CDA treatment), interview methods (to understand how discourse is received or resisted by audiences), and historical document analysis. The combination of corpus methods and CDA — sometimes called Corpus-Assisted Discourse Studies (CADS) — is particularly productive for large text collections.

CDA is feasible for thesis work if the student commits to learning the linguistic analytic categories their chosen framework requires. A dissertation that labels a few word choices as 'ideological' without systematic analysis will not pass CDA scrutiny. The practical advice is to choose one well-established framework (Fairclough's three-dimensional model is the most widely taught), apply it consistently, and be explicit about both the analytic steps taken and the researcher's critical standpoint.
