This textbook provides an accessible overview of the field of sociolinguistics.Blending qualitative and quantitative approaches and including examples drawn from different contexts and societies all over the world, the author introduces progressively complicated topics to help students build their confidence and understanding gradually as they work through the book.The chapters cover all the core topics on an introductory sociolinguistics course, including language and power, dialects, language and gender, language planning and multilingualism, and each chapter ends with a set of exercises, suggestions for small-scale projects which the author has used successfully with his own students and suggested further readings (both classic and more recent).This book assumes no background in Linguistics and is intended as an introduction to sociolinguistics that can be used at any level of undergraduate or graduate study, or by interested outsiders to the field.
