Sintesi	A critical single case study is a qualitative research design that investigates one bounded, strategically selected case through a critical-theory lens, aiming not only to understand the case in depth but also to expose underlying power relations, structural inequalities, or ideological conditions that shape the phenomenon. It combines the analytic depth of single-case inquiry with the emancipatory agenda of critical social science.	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.
