The Navajo language, or Diné bizaad, is the most widely spoken indigenous language in the U.S. In the late 19th century, the language rapidly declined as many members of the Navajo community were forced by colonists to learn English to replace their native language. Recent revitalization efforts focus not only on preserving and promoting the Navajo language, but also the culture, of which Diné bizaad is an integral part.
