The verb is the most important and the most complex part of Navajo grammar. For the first time, students and scholars interested in the Navajo language have a book that presents the verb system in a step-by-step and thorough fashion. By providing easy-to-follow descriptions with abundant examples, this book unravels the complexity of Navajo and reveals its expressiveness. In Navajo, numerous prefixes combine with verb roots to form single words that, in English translation, require a phrase or even a sentence to convey their meaning. Therefore, verb stems and prefixes must be mastered piece by piece to understand the language. This volume leads the reader carefully and systematically through the complexities of the Navajo verb system. By doing so, the book makes Navajo more accessible to all those interested in this American Indian language.
