Navajo

The Navajo, also spelled Navaho, is both the name of a large Native American nation surrounding Four Corners and the name for its people. The Navajo are closely related to the Apache. The Hopi live on an indian reservation within the Navajo reservation (Navajo Nation). Navajo call themselves Diné, a term from the Navajo language meaning people. The Navajo language is itself of some interest, and due to its high complexity it was used as a form of cryptography by the US military in the second world war; see codetalkers.

Navajo has several difficult consonants and consonant clusters. It is tonal; vowels have high or low tone, and if long can also rise or fall. Tone is indicated in writing by an acute accent; nasality is indicated by a mark under the vowel.

A few Navaho (and Hopi) live on the Colorado River Indian Tribes[?] reservation along the Colorado River in western Arizona. For information see Mohave.
