The Dakota language owes much of its expansiveness to its verbs, or action words. Yet until now, students of Dakota have had few resources in verb usage and conjugation beyond nineteenth-century dictionaries compiled by missionaries. 550 Dakota Verbs provides students of Dakota--and the Lakota and Nakota dialects--the proper conjugations for 550 verbs from adi (to step or walk on) to zo (to whistle). Compiled by Dakota language teachers and students, the book is learner friendly and easy to use. It features clear explanations of Dakota pronoun and conjugation patterns, notes on traditional and modern usages, and handy Dakota-English and English-Dakota verb lists. Designed to enhance everyday conversation as well as contribute to the revitalization of this endangered language, 550 Dakota Verbs is an indispensable resource for all who are interested in Dakota and its dialects, and a compliment to A Dakota-English Dictionary.
