Many different dictionaries exist for Native American languages. Access to these resources is available on websites such as the Native Languages of the Americas, Sage and Sweetgrass and the New Lakota Dictionary from the Lakota Language Consortium.
Native Languages of the Americas features links to purchase dictionaries for languages of numerous Native American tribes, including the Apache, Blackfoot, Cree, Creek, Delaware, Lakota, Maliseet, Mohawk, Ojibwe, Nahuatl, Salish and Tsimshian. Other linguistic resources available on the site are learning materials, grammar guides and folklore books.
Sage and Sweetgrass provides audio dictionaries for the languages of the Creek, Guale, Koasati, Lakota, Navajo, Oneida, Seminole and Taino tribes. Each dictionary is searchable based on English words beginning with or containing a certain letter.
The New Lakota Dictionary Online is an English-to-Lakota and Lakota-to-English dictionary. The site recommends downloading the desktop version of the dictionary because it has additional features such as frequent updates, an improved search tool, additional example sentences and audio pronunciation of words from native speakers. The software is available for Microsoft Windows and Mac OS X, as of 2015.
