"The combined efforts of Andrew Cowell and Alonzo Moss have not only produced a very important work on the Arapaho Language, but also a work that may be the most comprehensive grammatical analysis of Arapaho in print. While the book will be of substantial interest to linguists studying Algonquin languages, particularly those spoken in the plains, Cowell and Moss have put together a work that can also be useful for students hoping to learn Arapaho."- Neyooxt Greymorning, Great Plains Research
