Sintesi	Multiple case-based critical discourse analysis (multi-case CDA) combines the comparative logic of multiple case study design with the ideological and power-focused analytic apparatus of critical discourse analysis. The researcher selects two or more purposefully chosen cases, collects relevant texts or spoken discourse within each, applies CDA to reveal how language constructs power relations and ideologies within each case, and then synthesises findings across cases to identify patterns, contrasts, and broader sociocritical insights that a single-case design could not yield.	Discourse analysis is a qualitative research methodology that examines how language, communication, and power shape meaning, identity, and social reality. Developed across linguistics, sociology, and psychology (particularly by Norman Fairclough and Jonathan Potter), discourse analysis goes beyond content to analyze language use as a social practice that constitutes and reflects power relations, ideologies, and social structures.
