Résumé	Semiotic analysis is a qualitative method for interpreting how signs — words, images, sounds, gestures, and objects — produce and communicate meaning within a cultural context. Drawing on the structural linguistics of Ferdinand de Saussure and the triadic sign theory of Charles Sanders Peirce, and popularised as a research tool by Roland Barthes, semiotics moves beyond surface denotation to expose the connotative and ideological meanings embedded in texts and visual culture.	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.
