A book about applied linguistics is inevitably a book about language, its users and uses. Because the number of language users includes all 7.4 billion of us and language uses encompass almost all our myriad activities, from the most banal to the truly momentous, the subject weāre covering in this and the following thirteen chapters is remarkably wide-ranging. Itās a big topic to fit in a book made of paper and enclosed between covers of card, so itās inevitably going to spill over onto the companion website, get expanded in the recommended readings, well up and multiply in classroom discussion or discussion boards, and it wonāt be contained.
This first chapter is designed to provide some fixed points on our map of applied linguistics, describing points of departure, characteristic features of the terrain and ways not to go. In the chapter we do three things. First, we outline a broad perspective on human language that knits together its social and cognitive strands. The account, based on ideas from our sister discipline of general linguistics, informs all the other chapters in the book. Second, we identify ten fundamentally misguided ideas in everyday thinking about language, but argue that applied linguists need to acknowledge and respect them, because they are firmly embedded in most peopleās world views and determine many of their language-related decisions and practices. In other words, they are part of the territory. Our third and last goal here is to characterize the discipline of applied linguistics as we map it in this book. Ralph Waldo Emerson said that āTruth is the summit of being; justice is the application of it to affairsā (Emerson, 1987, p. 274). We wonāt try to scale any one summit, of course, because applied linguistics is a mountain range of many truths. We do, however, hope to give an initial flavour of how the discipline is united in its āapplication to affairsā and show that we all share the ultimate destination of social justice.
1.1 WHY DO WE USE DIFFERENT LANGUAGES?
1.2 TEN WAYS WEāRE LED ASTRAY IN LANGUAGE AND APPLIED LINGUISTICS
A āfolkā theory of language, capturing ācommon senseā beliefs, is a natural consequence of the āLanguage Spellā we mentioned in the previous section. All communities and cultures have deeply held beliefs about the nature of language and languages, which applied linguists ignore at their peril. But research in linguistics and allied fields allows us to bring new perspectives on the practical problems facing language users, which we must also be aware of if we are not to be led astray by tempting, but misleading, courses of belief and practice. Sometimes the straightest-looking route doesnāt lead to new territory, but ultimately sends us round in circles or soon dries up altogether. Here are our top ten ādead endsā. Although you might have your doubts right now (especially if youāre new to linguistics), weāll try to convince you, as we map applied linguistics in the chapters to come, that these dead ends are not the way to go.
