概要	Digital Critical Discourse Analysis (Digital CDA) is a qualitative research approach that applies the theoretical and methodological tools of Critical Discourse Analysis to digital and online communicative contexts. It examines how language, multimodal elements, and digital affordances are mobilized in online spaces to produce, reproduce, or contest power relations, ideologies, and social inequalities. Drawing on traditions established by Fairclough, Wodak, and van Dijk, Digital CDA treats digital texts — from social media posts to comment threads and websites — as sites of ideological struggle shaped by the platforms that host them.	Critical Discourse Analysis (CDA) is a qualitative method that examines how language in texts and talk constructs, sustains, and challenges relations of power, ideology, and social inequality. Drawing on linguistics, social theory, and critical philosophy, CDA treats discourse not merely as communication but as social practice — a site where dominance is reproduced and where resistance can be articulated. Developed in the late twentieth century by Norman Fairclough, Teun van Dijk, and Ruth Wodak, among others, CDA is applied to political speeches, media texts, policy documents, educational materials, and institutional interactions.
