This volume offers fresh, cutting-edge perspectives on issues of language and citizenship by casting a critical light on a broad spectrum of geo-political contexts - Flanders, Luxembourg, Singapore, South Africa, the UK - and discourse data - policy documents, newspaper articles, ethnographic notes and interviews, skits, bodies in protests. The main aims of the book are to investigate institutional discourses about the relationship between nationality and citizenship, and relate such discourses to more ethnographically grounded interactions; tease out the multiple and often conflicting meanings of citizenship; and explore the different linguistic/semiotic guises that citizenship might take on in different contexts. The book argues that the linguistic/discursive study of citizenship should not only include critical investigations of political proposals about language testing, but should also encompass the diverse, more or less mundane, ways in which various social actors enact citizenship with the help of an array of multivocal, material, and affective semiotic resources.
