The Wukchumni spoke traditionally a dialect of the
Tule-Kaweah Yokuts language, also called
Wukchumni.
Marie Wilcox, born 1933, was the last native speaker of Wukchumni. In the early 2000s, she and her daughter Jennifer Malone aimed to create a Wukchumni dictionary. She also worked on an audio dictionary with the aid of her grandson. Wilcox said that her grandparents taught her the language, but when her grandmother died, she had temporarily abandoned the Wukchumni language. When she realized that young tribal members were taking an interest in learning, she worked to make a lexical dictionary. Wilcox and her daughter taught weekly classes around
Tulare County. Wilcox was the only fluent speaker of Wukchumni in 2014. She died October 7, 2021. Due to her efforts, at least three people are fluent in the language as of 2021, and her great-great-grandson is being raised to speak it from birth. ==References==
