presents a broad critical survey of the research literature on child language development. Giving balanced coverage to both theoretical and empirical issues, William O'Grady constructs an up-to-date picture of how children acquire the syntax of English. Part 1 offers an overview of the developmental data pertaining to a range of syntactic phenomena, including word order, subject drop, embedded clauses, wh-questions, inversion, relative clauses, passives, and anaphora. Part 2 considers the various theories that have been advanced to explain the facts of development as well as the learnability problem, reporting on work in the mainstream formalist framework but also considering the results of alternative approaches. Covering a wide range of perspectives in the modern study of syntactic development, this book is an invaluable reference for specialists in the field of language acquisition and provides an excellent introduction to the acquisition of syntax for students and researchers in psychology, linguistics, and cognitive science.
