How is our language affected by our ethnicity, gender, and region? How are our conversations and other interactions structured? How does society view and regulate language? In this revised and updated second edition of the popular What Is Sociolinguistics? Van Herk guides the reader on a tour through the major issues that define the field, including region, status, gender, time, language attitudes, interaction, and style, at the same time exploring the sociolinguistics of multilingualism, culture and ethnicity, language contact, and education. This second edition has been revised and updated to include new and more exercises, discussion questions, and suggested readings, as well as expanded chapters exploring gender duality and Latino English. Key readings are introduced in Van Herk’s clear and engaging voice, which accompanies the text throughout, providing an accessible point of entry for those new to, or less familiar with, sociolinguistics. Chapter summaries and textboxes are similarly employed to signpost and illuminate learning. A companion website features PowerPoint slides for each chapter with suggestions for framing class discussions and exercises, further examples of concepts discussed, additional reading suggestions, and ready-to-go slides for class presentation. Packed with the latest research and practical teaching aids, What is Sociolinguistics? Second edition retains the highly-praised character of its predecessor and provides an essential up-to-date text for both students and instructors alike.
