This pedagogical approach to transformational grammar describes those aspects of the subject which have the greatest relevance for teachers of English. Following a definition of basic terms and a discussion of the nature and function of grammar, a description of basic English sentence patterns is used to present a model grammar based on the transformational theory. Morphemes, form and structure words, nouns, nominals, and verbs are then discussed and incorporated into the model grammar. An analysis of the transformational possibilities of adjectives and adverbs leads into methods of rearranging the basic sentences (e.g., interrogatives, negative and emphatic sentences, passive voices, and imperatives). A concluding chapter argues for a new understanding of the relation of grammar to the nature of language and to the study of literature. (LH)
