תקציר	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.	Multiple-case study design investigates two or more bounded real-world cases using the same research protocol, then compares findings across cases to identify patterns, contrasts, and explanatory insights that a single case could not produce. Developed primarily through Robert Yin's replication logic and Robert Stake's collective case tradition, the approach is particularly powerful when a researcher needs to determine whether a phenomenon occurs under varied conditions or to test an emerging theoretical explanation against rival contexts.
