Linguistics in language teaching

I have written Linguistics in Language Teaching for teachers of foreign languages including English as a foreign language. It is not an introduction to linguistics, nor is it a book on methodology. It is an attempt to bridge the gap between the two, to investigate how legitimately knowledge of linguistics contributes to the taking of decisions about language teaching. I have assumed that the reader has some familiarity with the methodology of language teaching but no previous knowledge of linguistics. It is most suitable, therefore, for the teacher about to start a course in linguistics or applied linguistics, or who wishes to see whether such a course is worth undertaking. I hope that it can also be read with benefit by teachers in training and with interest by students and teachers of general linguistics. - Preface.
