Historical Sociolinguistics is the study of the relationship between language and society in its historical dimension. This is the first textbook to introduce this vibrant field, based on examples and case studies taken from a variety of languages. Chapters begin with clear explanations of core concepts, which are then applied to historical contexts from different languages, such as English, French, Hindi and Mandarin. The volume uses several pedagogical methods, allowing readers to gain a deeper understanding of the theory and of examples. A list of key terms is provided, covering the main theoretical and methodological issues discussed. The book also includes a range of exercises and short further reading sections for students. It is ideal for students of sociolinguistics and historical linguistics, as well as providing a basic introduction to historical sociolinguistics for anyone with an interest in linguistics or social history.
