The purpose of Grammar for Teachers is to encourage readers to develop a solid understanding of the use and function of grammatical structures in American English. It approaches grammar from a descriptive rather than a prescriptive approach; however, throughout the book differences between formal and informal language, and spoken and written English are discussed. The book avoids jargon or excessive use of technical terminology. It makes the study of grammar interesting and relevant by presenting grammar in context and by using authentic material from a wide variety of sources.
