Drawing from various current grammar systems, this text provides a practical and easy-to-understand handbook of grammar for readers of expository prose (language written for explanation and read for understanding). The analysis in the book is designed to perform two functions: (1) help readers receive with clarity, if at all possible, the communication intended by writers; and (2) provide a basis, depending on purpose, for achieving efficiency in this reading process. The diagramming system in the book is organized around "word nests" that illustrate and clarify grammatical relationships with greater efficiency than the traditional "fishhooks." (KEH)
