概要	Interpretive semiotic analysis is a qualitative method that examines how signs — words, images, symbols, gestures, and sounds — produce meaning within specific social and cultural contexts. Drawing on Saussurean semiology and Barthesian cultural analysis, the approach moves beyond surface-level description to uncover the layered, context-bound meanings that sign systems generate. It is widely used in media studies, communication, education, marketing, and cultural research to reveal how representations shape social reality.	Interpretive critical discourse analysis (interpretive CDA) combines the power-and-ideology lens of critical discourse analysis with an interpretivist epistemology that foregrounds meaning-making, context, and the researcher's own positionality. It examines how language constructs social reality, legitimises or challenges power relations, and circulates ideological assumptions — while acknowledging that both the texts under study and the analyst's reading of them are socially situated and context-dependent.
