Nisenan language
Nisenan (or alternatively, Neeshenam, Nishinam, Pujuni, or Wapumni) is a nearly[citation needed] extinct Maiduan language spoken by the Nisenan people of central California in the foothills of the Sierras, in the whole of the American, Bear and Yuba river drainages.Most notably the release of the "Nisenan Workbook" (three volumes so far) put out by Alan Wallace, which can be found at the California State Indian Museum in Sacramento and the Maidu Interpretive Center in Roseville.[citation needed] As the Nisenan (like many of the Natives of central California) were not a unified nation but a collection of independent tribes which are grouped together primarily on linguistic similarity, there were many dialects to varying degrees of variation.The Nisenan Workbooks depict these in transcription, though the sound guides have yet to distinguish them from the plain plosives.One source noted an audible click with /b/ and /d/ among some older speakers of at least one dialect of one of the Maiduan languages.
