Language is involved in processes of group identification in that it provides a focus for explicit discourses of identity and constitutes a field of less overt practices for creating groupness. Drawing on examples from Mauritian television broadcasting, this study traces the ethnicization of Mauritian Bhojpuri as a "Hindu language" through the hierarchization and subsuming of linguistic practices under larger language labels with ethno-national significance. Purist forms of Mauritian Bhojpuri that are locally perceived as "intermediate" registers between Hindi and Bhojpuri are used to represent Hindi as a language spoken in Mauritius, and at the same time to link Mauritian Bhojpuri ideologically to Hindu identity. This blurring of language boundaries serves a Hindu nationalist agenda in a diasporic location by establishing new links between linguistic forms and ethno-national values.
