The Arapaho language, also called Arapaho proper, is one of the Plains Algonquian languages and spoken by under 300 people in Wyoming and Oklahoma all over the age of 50. Thus the language was in danger of being extinct. In 2008 a grammar was published and the authors estimated 250 people were fluent. Since then a school has been opened to teach Arapaho to children in an effort to preserve and revive the language. Arapaho is truly a precious language, one of the Proto-Algonquian languages the Great Plains, and truly unique among world languages as it contains no low vowel sounds. Baby Name World does maintain some Native American baby names and name meanings including Arapaho, Apache and Navajo names.
