In my dissertation, I investigate the linguistic and cultural practices among adolescents with ethnic minority backgrounds when they interact with peers and teachers at school, with immediate family members at home, and with peers on social media sites. I look into their local language practices while simultaneously relating the practices to broader societal discourses to see if and how the adolescents and their families respond to them. I argue that in order to describe the participants’ diverse practices, it is necessary to approach these aspects empirically through language and everyday interactions. I have done so with linguistic ethnography as the basic methodological orientation for my research, and my study is based on various kinds of spoken and written data material, which have been collected during a two and half year long ethnographic fieldwork at a Copenhagen based school.
