This book is intended primarily for undergraduate students ofEnglish, though it will also be useful for undergraduates inlinguistics focusing on English. It shows how a restricted set ofprinciples can account for a wide range of the phenomena of Englishsyntax. While the main focus of the book is empirical, it introducesimportant theoretical concepts: theta theory, X-bar theory, casetheory, locality, binding theory, economy, full interpretation,functional projections. In doing so it prepares the student formore advanced theoretical work. The authors integrate many recentinsights into the nature of syntactic structure into theirdiscussion. They present information in a gradual way: hypothesesdeveloped in early chapters are reviewed and modified in subsequentones. The authors also pay attention to the relation betweenstructure and interpretation and to language variation, andparticularly to register variation. They include a wide range ofdiverse exercises, giving the student an opportunity for creativeindividual work on English.
