This chapter outlines the ethnographic and qualitative methodology employed in this study. The methodological choices focus on understanding language ideologies in a multilingual setting. The study does not engage in a linguistic focus on speech patterns and instead emphasizes the cultural and social meanings that speakers attach to language. It challenges monolingual, Western-centric assumptions by exploring complex links between language and social structures. Data collection included interviews, field notes, observations, classroom recordings, and surveys on language use. The study uses grounded theory to analyse data, and it prioritizes speakers’ perspectives as experts of their own language culture. The chapter argues that decolonising research practices have to treat local language ideologies as legitimate frameworks rather than folk beliefs. A linguistic analysis examines public English, inspecting its variability and influence from both local and external norms. By integrating linguistic, cultural, and social data, the methodological approach provides a holistic view of how language ideologies emerge and intersect with broader social discourses.
