This article deals with the politics of classification in contemporary Sweden. It analyses the language political dispute that has developed over the language political regulation of Ö vdalsk, a non-standard form of Scandinavian spoken in Ä lvdalen in northern central Sweden. The analysis focuses on the ways in which a discursive exchange over metalinguistic categories contributes to the efficacy of a state vision of linguistic divisions. In the wake of Sweden's ratification of the European Charter for Regional and Minority Languages (ECRML), and the language political reforms in which the ratification was embedded, Ö vdalsk has emerged as a contentious issue. Over three decades (1990s-2010s), the question of what Ö vdalsk 'is'-a 'language', a 'dialect' or something else-has surged repeatedly in political, public and scholarly deliberations (i.e. in expert reports, in policy documents and in scientific publications). Nevertheless, the interests placed in this muddled taxonomic issue have not yet been subjected to any sociolinguistic analysis. Drawing on Bourdieu's work on the state, the article attends to the ways in which the exchange over Ö vdalsk has paid tribute to an increasingly entrenched symbolic order. Commenting on Sweden's commitment to the ECRML more generally, the article accounts for how and why an officialised vision of linguistic division has been rendered symbolically effective. Accordingly, the article argues that a sensitisation to the forms of tacit agreement that underwrite contention is a suitable lens for grasping the maintenance of a political order as legitimate and effective.
