Advanced Grammar introduces basic concepts of English grammar by reinforcing the fact that the infinite variety of sentences produced by every speaker is governed by a small set of rather simple rules. It presents information about history to emphasize that English is a constantly changing language, a subject that readers will find intriguing. The book provides great detail about a broad array of constructions (passive, negative, questions, tag questions, existentials, clefts, fronting, left and right dislocation, emphasis, contrast, subordination, and conjoined sentences) and gives more information about sentence structure (especially the auxiliary system) than any other book on the market. It combines all subfields of linguistics and presents them in an integrated manner so that readers can easily see how all of language is an interconnecting system. Excellent as a reference source for employees in fields where writing effectively for business is necessary.
