1. One reason for this divide is that while the communicative approach drew its initial inspiration from linguistics, it now looks increasingly related to educational theory, psychology and ethnography.

2. In other words, nowadays, although linguistics is still necessary as it has a part to play in communicative language approach, for many practitioners it has only a supporting role.

3. About fifteen or twenty years ago applied linguists and language teaching specialists thought they had found the great overarching principle that would guide the development of the subject into the twenty-first century: the communicative approach.

4. We do not agree with this present status of linguistics, so we aim in this book to show that linguistics does indeed have the potential to be a star, to match the performance of those players at present strutting the stage.

5. Yet today it seems that there is a deep and uncomfortable divide in the field of communicative approach which relates to linguistics.

But first we need to look at the linguistic origins of the communicative approach, then trace its drift away from its parent discipline.
