Chinookan is a small family of languages spoken in Oregon and Washington along the Columbia River by Chinook peoples.
Chinookan consists of three languages with multiple varieties. There is some dispute over classification, and there are two ISO 639-3 codes assigned: chh (Chinook, Lower Chinook) and wac (Wasco-Wishram, Upper Chinook). For example, Ethnologue 15e classifies Kiksht as Lower Chinook, while others consider it instead Upper Chinook (discussion), and others a separate language.
Consonants
The glides [j], [w] are analyzed as allophones of the high vowels.
As in many North American Languages, verbs constitute complete clauses in themselves. Nominal may accompany the verbs, but they have adjunct status, functioning as appositives to the pronominal affixes. Word order functions purely pragmatically; constituents appear in decreasing order of newsworthiness. Clauses are combined by juxtaposition or particles, rather than subordinating inflection.
Chinookan peoples include several groups of indigenous people of the Pacific Northwest in the United States speaking the Chinookan languages. In the early 19th century, the Chinookan-speaking peoples resided along the lower and middle Columbia River but in present-day Oregon and Washington. The Chinook tribes were those encountered by the Lewis and Clark Expedition in 1805 on the lower Columbia.
Since the late 20th century, the Chinook Indian Nation, made up of 2700 members of several peoples, has worked to obtain federal recognition. It gained this in 2001 but, after President George W. Bush took office, his political appointees revoked that status in 2002. The tribe continues to seek recognition.
The Chinookan peoples were not nomadic but rather occupied traditional tribal geographic areas. They had a form of society marked by social stratification consisting of a number of distinct social castes of greater or lesser status. Upper castes included shamans, warriors, and successful traders, and were a minority of the community population compared to common members of the tribal group. Members of the superior castes are said to have practiced social isolation, limiting contact with commoners and forbidding play between the children of the different social groups.
