This collection of articles written over a period of 10 years concerning the transformational syntax of English has been divided into six sections. The articles in the first section provide background material for the reader with no specialized linguistic preparation. They present the fundamental questions that linguists are now asking, some of the problems faced in answering these questions, and the notational devices and conventions of transformational description. Sections 2 through 5 treat specific aspects of English structure. Articles appear concerning conjunction, pronominalization, relativization, English comparative construction, phrase structure principles of English complex sentence formation, attachment transformations, adjectives as noun phrases, and a modern theory of case. The sixth section contains articles discussing applications and implications of the transformational approach in such areas as historical change, child language, metrics, and language teaching.
