Critical discourse analysis (CDA) is an interdisciplinary approach to the study of discourse that views language as a form of social practice. CDA combines critique of discourse and explanation of how it figures within and contributes to the existing social reality, as a basis for action to change that existing reality in particular respects. Scholars working in the tradition of CDA generally argue that (non-linguistic) social practice and linguistic practice constitute one another and focus on investigating how societal power relations are established and reinforced through language use. In this sense, it differs from discourse analysis in that it highlights issues of power asymmetries, manipulation, exploitation, and structural inequities in domains such as education, media, and politics.
