สรุป	Metaphor Analysis is a qualitative method that identifies, classifies, and interprets the metaphors embedded in language to reveal how speakers and writers conceptualise experience, construct meaning, and exercise ideological influence. Grounded in Lakoff and Johnson's Conceptual Metaphor Theory, it treats metaphor not as a literary decoration but as a fundamental cognitive structure — ARGUMENT IS WAR, TIME IS MONEY — that shapes how people think, reason, and act. It is widely applied in psychology, education, political discourse, health communication, and organisational research.	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.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
