Navajo is spoken in the American Southwest (primarily Arizona, New
Mexico, and Utah) by the Navajo people, or Dine'. The largest of all the
Native American tribes, the Navajo are one of the few tribes that still
use their native language in everyday communication. The Navajo language
first appeared in writing in the mid-1800s. In 1939, the alphabet was
standardized and printed materials were available. Shortly after, during
World War II, bilingual "code talkers" sent secure radio messages using
Navajo as a code. Includes over 9,000 entries; a detailed section on
Navajo pronunciation; and useful, everyday expressions.
