Understanding Language Structure, Interaction, and Variation is an introduction to the study of language and applied linguistics for students who have had a minimum of exposure to the discipline of linguistics. Using clear, easy-to-understand explanations and examples, this text avoids the in-depth theoretical coverage found in texts written for those who specialize in linguistics or SLA. As a result, this book is perfect for students whose chosen fields require them to be acquainted with the ways language works--such as future teachers, psychologists, sociologists, and anthropologists--but who do not intend to become linguists. The text is also suitable for English or ESL/EFL teachers who need a reference volume about various aspects of language, particularly as it applies to teaching. Each chapter includes research projects and further readings.

The third edition of Understanding Language Structure, Interaction, and Variation features a new design and reorganization. All content has been significantly revised and updated. Each chapter also debunks a common language myth and now incorporates exercises that, for prior editions, appeared in a supplementary workbook. Extra practice for students is available online, as is additional materials for teachers. (There is no workbook for the third edition.)
