The Navajo language is itself of some interest: 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 it also rise or fall. Tone is indicated in writing by an acute accent; nasality is indicated by a mark under the vowel.
