Bringing together work from a team of international scholars, this groundbreaking book explores how language users employ translingualism playfully, while, at the same time, negotiating precarious situations, such as the breaking of social norms and subverting sociolinguistic boundaries. It includes a range of ethnographic studies from around the globe, to provide us with insights into the everyday lives of language users and learners and their lived experiences, and how these interact in translingual practices. A number of mixed methodological frameworks are included to study language users' behaviours, experiences and actions, cover the complexity of language evolutionary processes, and ultimately show that precarity is as fundamental to translingualism as playfulness. It points to a future research direction in which research should be pragmatically applied into real pedagogical actions by revealing the sociolinguistic realities of translingual users, fundamentally addressing broader issues of racism, social injustice, language activism and other human rights issues.
