This book is about how urban linguistic landscapes reflect and create sociolinguistic, societal and urban dynamics, and how these relations can be scientifically explored. Focusing on the linguistic landscapes of selected cities in northern and southern Europe, it sheds light on how urban areas with diverse profiles differ, and how the linguistic landscapes change through tourism and migration, or in times of crisis. The chapters put forward sophisticated and novel ways of approaching urban sociolinguistics and they enhance understanding of the challenges and opportunities included in the study of sociolinguistic variation in these linguistic landscapes.
