Wichita language
Updated: Wikipedia source
Wichita is a Caddoan language that was spoken in Anadarko, Oklahoma, by the Wichita and Affiliated Tribes. The last fluent heritage speaker, Doris Lamar-McLemore, died in 2016. This has rendered Wichita functionally extinct; however, the tribe offers classes to revitalize the language and works in partnership with the Wichita Documentation Project of the University of Colorado, Boulder.
