This book is an original study of the nature and place of pedagogic grammar in the teaching and learning of languages. It offers a fresh view of language organization, informed by current linguistic and psycholinguistic research. The book invites the reader to explore the relationships among language form, language learning, and language teaching and thus to determine the natural place of grammar in the pedagogic programme. In accomplishing this, the thrust of the book is not so much upon the formation of grammatical constructs but rather upon the shape of the grammatical system, and its relation to semantics, discourse and pragmatics.
