Hopi, spoken in northern Arizona, is a member of the large Uto-Aztecan family of American Indian languages, which spreads over vast portions of the western United States and Mexico. The Hopi language textbook is directed at non-specialists who want to learn to speak Hopi or who simply want to learn something about the language. The content of the book consists of 30 lessons starting with the basic sounds of Hopi, covering fundamental points of Hopi grammar one by one, and leading the student to the construction of highly complex sentences. The grammatical material is introduced simply and with concrete illustrations at every point, and each lesson includes a variety of exercises with answers provided to help the student master the points presented. Interspersed with the lessons are 10 dialogs illustrating natural Hopi speech in specific situations. A limited amount of new vocabulary is introduced in each lesson and dialog. Hopi-English and English-Hopi lexicons summarize the vocabulary at the end of the volume. In addition, there are three short readings and four appendices pertaining to numbers, color terms, names of Hopi villages, and kinship terminology. (ERB)
