This work is designed, firstly, to both provoke theoretical discussion and serve as a practical guide for researchers and students in the field of corpus linguistics and, secondly, to offer a wide-ranging introduction to corpus techniques for practitioners of discourse studies. It delves into a wide variety of language topics and areas including metaphor, irony, evaluation, (im)politeness, stylistics, language change and sociopolitical issues. Each chapter begins with an outline of an area, followed by case studies which attempt both to shed light on particular themes in this area and to demonstrate the methodologies which might be fruitfully employed to investigate them. The chapters conclude with suggestions on activities which the readers may wish to undertake themselves. An Appendix contains a list of currently available resources for corpus research which were used or mentioned in the book.
