Language is on display all around us, all the time, and the study of this linguistic landscape is one of the fastest-growing areas of research in applied linguistics. This book provides an overview of how the field of Linguistic Landscape Studies has emerged and developed over the past 20 years, combined with an in-depth exploration of the theoretical approaches, innovative research methods and major themes that have been central to this dynamic area of research. Written by two authors who have been involved in the field from its inception, the book features summaries of studies from around the world, a discussion of the future of the field, and an analysis of the impact of linguistic landscape research on language policy, language learning and teaching, and minority language revitalization. It will be an invaluable companion for students and researchers in Linguistic Landscape Studies, as well as to those working in related areas.
