Uto-Aztecan, “A website for Uto-Aztecan Studies,” is a welcome new addition to the internet, and just the sort of thing that the internet is ideal for. Brian D. Stubbs, who created the site, writes:
Welcome to Uto-Aztecan.org, a website devoted to the comparative study of the Uto-Aztecan (UA) language family. Located in the southwestern United States and western Mexico, UA consists of some 30 related Native American languages descended from a common parent language that linguists now call Proto-Uto-Aztecan (PUA). Hopi, Ute, Pima, and Aztec/Nahuatl are among the better known of UA languages. The valuable works of many linguists are listed in the bibliography and some are discussed in the introduction accessible above and will be cited here increasingly over time, but the initial offerings are portions of the book, A Uto-Aztecan Comparative Vocabulary (by brian stubbs), available on this website, intended to encourage and facilitate the comparative study of Uto-Aztecan languages.
The book presently contains some 2650 Uto-Aztecan cognate sets (groups of related words), which is only the latest plateau of progress or new foundation for future research. After three decades of studying UA and compiling the book, I realized that an undertaking as large as a language family has no end, like running a race without a finish line. Each new discovery creates rows of ripples of adjustments to so much else, and there is no end to new discoveries[…]
You can read more at the Introduction page, and of course sample the various offerings of the site. (Thanks, Yoram!)
