Tóm tắt	Comparative discourse analysis examines how language constructs meaning, identity, and power by systematically contrasting texts or speech acts drawn from at least two distinct contexts, groups, time periods, or institutions. By holding analytical categories constant across cases, it reveals how discursive patterns diverge or converge, producing insights that single-context discourse analysis cannot generate.	Comparative Thematic Analysis applies the structured procedures of thematic analysis across two or more distinct groups, sites, or time points, with the explicit aim of identifying both shared patterns and meaningful differences. Rather than producing a single composite account of experience, it yields a layered analysis that maps where themes converge and diverge across comparison units — making it especially valuable for policy-relevant, cross-cultural, or multi-site qualitative studies.
