Overview
Yavapai is an Upland Yuman language, spoken by Yavapai people in central and western Arizona. There are four dialects: Kwevkepaya, Wipukpaya, Tolkepaya, and Yavepe. Linguistic studies of the Kwevkepaya (Southern), Tolkepaya (Western), Wipukepa (Verde Valley), and Yavepe (Prescott) dialects have been published (Mithun 1999:578).
Yavapai was once spoken across much of north-central and western Arizona, but is now mostly spoken on the Yavapai reservations at Fort McDowell, the Verde Valley and Prescott.
Geographic distribution
The rate of mutual comprehension between Yavapai and Havasupai–Hualapai is similar to that between Mohave and Maricopa (Biggs 1957).
Warren Gazzam, a Tolkapaya speaker, reported that "you know they (Hualapais) speak the same language as we do, some words or accents are a little different".
