In this dictionary of the Nez Perce language, which is spoken in the states of Idaho, Oregon, and Washington, the author illustrates how each word is used by citing examples from published Nez Perce oral literature; the dictionary is thus also a concordance. In addition, the author retranscribes and incorporates words from earlier publications, when recognized by today's Nez Perce speakers. The dictionary includes an English-Nez Perce index, appendixes listing phonosymbolic words and Nez Perce animal and plant names, and illustrations from Nez Perce life.
