The Routledge English Language Introductions are 'flexi-texts' that you can use to suit your own style of study. The books are divided into four sections:
A Introduction - sets out the key concepts for the area of study. The units of this section take you step-by-step through the foundational terms and ideas, carefully providing you with an initial toolkit for your own study. By the end of the section, you will have a good overview of the whole field.
B Development - adds to your knowledge and builds on the key ideas already introduced. Units in this section might also draw together several areas of interest. By the end of this section, you will already have a good and fairly detailed grasp of the field, and will be ready to undertake your own exploration and thinking.
C Exploration - provides examples of language data and guides you through your own investigation of the field. The units in this section will be more open-ended and exploratory, and you will be encouraged to try out your ideas and think for yourself, using your newly acquired knowledge.
D Extension - offers you the chance to compare your expertise with key readings in the area. These are taken from the work of important writers, and are provided with guidance and questions for your further thought.
You can read this book like a traditional text-book, 'vertically' straight through from beginning to end. This will take you comprehensively through the broad field of study. However, the Routledge English Language Introductions have been carefully designed so that you can read them in another dimension, 'horizontally' across the numbered units. For example, Units A1, A2, A3 and so on correspond with Units B1, B2, B3, and with Units C1, C2, C3 and D1, D2, D3, and so on. Reading A5, B5, C5, D5 will take you rapidly from the key concepts of a specific area to a level of expertise in that precise area, all with a very close focus. You can match your way of reading with the best way that you work.
The index at the end, together with the suggestions for further reading, will help to keep you orientated. Each textbook has a supporting website with extra commentary, suggestions, additional material and support for teachers and students.
