Sintesi	Transcendental phenomenology, founded by Edmund Husserl, is a qualitative method that seeks the universal essential structures — the invariant essences — of a consciously lived experience. By bracketing all assumptions and prior theories (epoché) and applying eidetic reduction, the researcher uncovers what an experience is in its purest, most fundamental form, independent of any particular context, culture, or individual biography. Clark Moustakas's 1994 adaptation made the method directly accessible to social-science researchers.	Case study research is a qualitative research design that investigates a specific phenomenon, individual, group, organisation, or event in depth within its real-world context. Systematised by Robert K. Yin in 1984, it supports single-case and multiple-case designs and draws on multiple data sources — interviews, observation, documents, and artefacts — to build a rich, contextualised account of a bounded unit.	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.
