Navajo or Navaho (/ˈnævəhoʊ, ˈnɑː-/; Navajo: Diné bizaad [tìnépìz̥ɑ̀ːt] or Naabeehó bizaad [nɑ̀ːpèːhópìz̥ɑ̀ːt]) is a Southern Athabaskan language of the Na-Dené family, through which it is related to languages spoken across the western areas of North America.

The language has a fairly large phoneme inventory; it includes several uncommon consonants that are not found in English. Its four basic vowels are distinguished for nasality, length, and tone. It has both agglutinative and fusional elements: it relies on affixes to modify verbs, and nouns are typically created from multiple morphemes, but in both cases these morphemes are fused irregularly and beyond easy recognition. Basic word order is subject–object–verb, though it is highly flexible to pragmatic factors. Verbs are conjugated for aspect and mood, and given affixes for the person and number of both subjects and objects, as well as a host of other variables.
