This book gives a thorough, yet easily accessible introduction to the main branches of English linguistics. The book is aimed at beginning and intermediate students of English who have little or no previous experience in doing linguistics, and who are expected to achieve a working knowledge of English morphology, syntax and semantics. The book contains a large number of written exercises which allow the students to practice linguistic reasoning and their own argumentation skills. The students will also learn how to use secondary material, such as dictionaries and various types of internet sources, to support their analyses and argumentation. The book is accompanied by a website containing, among other things, audio material and short podcasts on complex topics as well as keys to the exercises in the book.
