<div> <P style="LINE-HEIGHT: 200%; MARGIN: 0in 0in 0pt" class=MsoNormal><I>Understanding Language Structure, Interaction, and Variation </I>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. <P style="LINE-HEIGHT: 200%; MARGIN: 0in 0in 0pt" class=MsoNormal> </P> <P style="LINE-HEIGHT: 200%; MARGIN: 0in 0in 0pt" class=MsoNormal>The third edition of <I>Understanding Language Structure, Interaction, and Variatio</I>n 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.) </DIV>
