There have been very few attempts at so comprehensive a coverage as is offered in the present work. Fewer still in terms of synchronic description. And none at all so comprehensive or in such depth has been produced within an English-speaking country. Moreover, our Grammar aims at this comprehensiveness and depth in treating English irrespective of frontiers: our field is no less than the grammar of educated English current in the second half of the twentieth century in the world's major English-speaking communities. - Preface.
