With cultural and linguistic diversity, migration, and constant change as defining features of contemporary societies, it is increasingly necessary to enhance our capabilities within multilingual environments. Reconceptualizing Language Norms in Multilingual Contexts offers a groundbreaking exploration of language practices and norms in the diverse and dynamic world we inhabit today. It challenges the traditional understanding of language norms as stable and stationary. Instead, it embraces multiculturalism and multilingualism as the norm rather than the exception. Drawing upon a wide range of methodological approaches, this book brings together a collection of position papers, critical reflections, and explorations by emerging and established voices in the field. It delves into how language norms emerge, evolve, and shape communication in both collective and individual contexts of diversity. By reconceptualizing language norms, this book sheds light on real and relevant language practices in multilingual and multicultural spaces, offering insights from the people who inhabit and navigate these contexts. While the content of this book revolves around everyday communication, its academic approaches and comprehensive exploration make it a valuable resource for graduate students, educators, and researchers in the fields of multilingualism and applied linguistics. By bridging the gap between language norms and multilingualism, this book seeks to advance our understanding of language practices in the increasingly interconnected and diverse world.
