We use language everyday in every aspect of our lives, whether at school, work, or home, with friends, colleagues or family. The ability to use language is so important that it defines what makes us human. Yet what is language? And how does it work? In this introduction to language, Peter Sharpe answers a series of questions about language to show its inner workings. Drawing on expertise from many disciplines, he examines the origins of language, how language produces meaning, the variation of language across cultures, how language is used in society, and whether or not there is a correct way to use language. Discussion questions at the end of each chapter, and signposts for further reading make this the essential introduction to language for inquisitive readers and undergraduates.
