Wukchumni (Tule–Kaweah Yokuts)

• People / language: Wukchumni people, a Yokuts people; Wukchumni (Wikchamni) — the last surviving dialect of Tule–Kaweah Yokuts, Yokutsan family
• Region: East fork of the Kaweah River, San Joaquin Valley / Tulare County, California, USA

STATUS

Extinct as a native-speaker dialect (2021); a small number of new fluent speakers made by the last speaker's own teaching. Marie Wilcox was the last native speaker. At her death there were at least three fluent speakers — all of them learners she and her family had taught — and her great-great-grandson is being raised speaking the language, so the honest status line is double: the unbroken native line ended in 2021, and a taught line continues. On the EGIDS scale Wukchumni was categorised 8a, "moribund," in 2019.

THE COUNT

• 2014: one fluent speaker. "Wilcox was the only fluent speaker of Wukchumni in 2014" (New York Times, "Who Speaks Wukchumni?", 19 Aug 2014).
• 2021: at least three fluent speakers at her death — the product of Wilcox's dictionary work and the weekly classes she taught with her daughter (New York Times obituary, 6 Oct 2021; Washington Post, 8 Oct 2021). These are second-language fluent speakers; the native-speaker count went from one to zero.
• Death date — sources conflict, flagged: the New York Times obituary reports Marie Wilcox died 25 September 2021, aged 87, in Visalia, after her aorta ruptured. One line in the Wukchumni reference article gives 7 October 2021. This register follows the NYT obituary (25 September 2021) and records the discrepancy rather than silently choosing.

WHAT HAPPENED

• The Yokuts peoples of the San Joaquin Valley were reduced across the 19th and 20th centuries by the same California sequence documented throughout this register's California entries — mission and ranchero eras, Gold Rush-era violence, land loss, and schooling in English — until, of Tule–Kaweah's three dialects (Wukchumni, Yawdanchi, Bokninuwad), only Wukchumni still had a living speaker, and by the early 2010s, after a relative's death, that speaker was one woman.
• Wilcox's own account of the mechanism is personal and precise: her grandparents taught her the language; when her grandmother died she temporarily abandoned it; she returned to it when young tribal members showed interest in learning — transmission had narrowed to a single household line, and she chose to rebuild it deliberately.

WHAT SURVIVES

• The Wukchumni dictionary: Wilcox worked more than 20 years compiling it — remembering, relearning, and setting down the language — with her daughter Jennifer Malone and computer help from Nicholas Luna. The dictionary was copyrighted in 2019 but has not been published (status as last reported); she also recorded an oral/audio version with pronunciations, and traditional stories.
• The teaching line: Wilcox and Malone taught beginner and intermediate Wukchumni classes to tribal members around Tulare County; Malone continues the teaching (Owens Valley Career Development Center). At least three fluent speakers (above) and Oliver, Wilcox's great-great-grandson, being raised by her great-granddaughter Destiny Treglown as a Wukchumni speaker — if he reaches fluency he will be the first native speaker in four generations.
• The film: Marie's Dictionary (2014), a short documentary by Emmanuel Vaughan-Lee (Global Oneness Project / New York Times Op-Docs), which carried her work worldwide and drew new learners to the classes.
• Revitalisation is additionally organised through the Master-Apprentice Language Learning Program (California).
