Plateau Penutian languages


Plateau Penutian is a family of languages spoken in northern California, reaching through central-western Oregon to northern Washington and central-northern Idaho. The family is accepted by Campbell.

Plateau Penutian is hypothesized to consist of four languages:Plateau Penutian

History

Plateau Penutian, as originally proposed, was one branch of the hypothetical Penutian phylum as proposed by Edward Sapir. The original proposal also included Cayuse ; however, this language has little documentation and that which is documented is inadequately recorded. Thus, the status of Cayuse within Penutian may very well forever remain unclassified.
The Sahaptian grouping of Sahaptin and Nez Percé has long been uncontroversial. There is evidence in support of a connection between Klamath and Sahaptian. Howard Berman also provides evidence that would include Molala within Plateau Penutian.
Appraisals of the Penutian hypothesis in the 1990s find Plateau Penutian to be "well supported", with DeLancey & Golla cautiously stating "while all subgroupings at this stage of Penutian research must be considered provisional, several linkages show considerable promise". Other researchers have pointed out similarities between Plateau Penutian and the Maiduan family, although this proposal is still not completely demonstrated. A connection with Uto-Aztecan has also been suggested. The Glottolog classification, favored by many linguistic typologists but considered too conservative by some, disregards Plateau Penutian entirely.

Computational analyses

A study published in 2013 using an automated computational analysis of 40 basic vocabulary items resulted in languages from Plateau Penutian showing similarities that could be interpreted as genealogical cohesion. However, when describing the method, the authors of the study also concede that similarities may be due to borrowings and areal diffusion. Moreover, the use of automated methods for establishing genealogical connections is controversial, with many historical linguistics still favouring analyses using the comparative method, which places high importance on morphological similarities, especially when found in irregularities.
