High Quality Content by WIKIPEDIA articles! Wichita is a moribund Caddoan language spoken in Oklahoma by the Wichita and Affiliated Tribes. Only one fluent speaker remains, Doris McLemore, although in 2007 there were only three first language learners still alive. Wichita could soon become extinct, however, the tribe offers classes to revitalize the language and works in partnership with Wichita Documentation Project of the University of Colorado, Boulder.
