This work has everything you could want from a dictionary and more. Crystal-clear presentation, useful examples, cross-references to other useful words, and even a thorough grammar section! Entries are given in their standard orthography, which is easy for learners to grasp, and have apparently all been checked by native speakers of the Lakota language. It is quite a chunky book but I suppose this is a testament to how comprehensively it documents the endangered language. It is this work that restored my motivation in trying to learn it myself, having toyed with older, less accessible materials.
Buy, beg, borrow or steal it! If you're serious about studying Lakota, you can't afford to be without the NLD. As a learner, this is the book I've been waiting for. It's the best Lakota/English and English/Lakota dictionary available. Unique to the NLD is the inclusion of the Dakota dialects variants. Far more than just a word-list, the entries are packed with example sentences, paradigms are included in the verbs, there is information on usage and culture, the most frequently used words are marked. The grammar section explains the basics of Lakota grammar simply and clearly and is extremely informative. Because of the economical use of diacritics and the marking of stress in the LLC orthography, it is very easy to pronounce each word correctly. If you read the History of Lakota Lexicography in the introduction to the dictionary, you will understand why this is really the first reliable Lakota dictionary ever. With every entry and example sentence double-checked by native speakers, it is totally trustworthy, reflecting modern usage of the language whilst making one aware of the richness and beauty of the Lakota language.
