Scholars have long critiqued points of view in which monolingual perspectives are seen as normative in research on multilingualism. In relation to this "monolingual orientation," however, in which monolingualism is perceived to be the implicit norm, less work has been dedicated to methodological challenges. As disciplinary perspectives on language in Linguistics and related fields move further towards the de-emphasizing and deconstructing of the boundaries between named linguistic varieties, this paper addresses some issues that come up in operationalizing this in our research. It does so through self-reflexivity, from a primarily Sociolinguistic and Applied Linguistic point of view, by addressing monolingual perspectives found in data on a project on multilingual practices in India. It focuses more narrowly on the ethnographic field notes from the research context. With discourse analysis, these are looked at through the lens of the monolingual orientation, with a particular focus on language ideologies and the compartmentalization of named-language varieties. Ideologies in the data are discussed in relation to their bearing on methodology in transcribing, coding, and the framing of research questions. This paper explores the tensions between evolving theoretical perspectives and on-the-ground research practice, concluding by proposing questions for reflection.
