Spanish is an important source for terms and expressions that have made their way into the English of the southwestern United States. Vocabulario Vaquero/Cowboy Talk is the first book to list all Spanish-language terms pertaining to two important activities in the American West?ranching and cowboying?with special reference to American Indian terms that have come through Spanish. In addition to presenting the most accurate definitions available, this A-to-Z lexicon traces the etymology of words and critically reviews and assesses the specialized English sources for each entry. It is the only dictionary of its kind to reference Spanish sources. The scholarly treatment of this volume makes it an essential addition to the libraries of linguists and historians interested in Spanish/English contact in the American West. Western enthusiasts of all backgrounds will find accessible entries full of invaluable information.
