Tawɨ

The Southern Uto-Aztecan root *tawɨ "sun", has a wide range of reflexes.

Nahuatl:

to:na "heat", to:nal-li "heating, sun", to:natiw "sun, it goes heating"

tlawia "to light something", tlawilli "light, dawn"

tlawiskalpan "dawn house" (mythological location in the eastern ocean), Tlawiskalpantekʷtli "dawn lord" (morning star deity)

tlatlawki "red"

Wixárika

tau < *táwè

Stubbs

For SUA Stubbs seems to imply a short root *ta'a "sun", with a longer root *tawɨ "day". It looks to me as if the opposite is more likely and that the short forms in Cahitan and Tarahumara-Guarijío are shortened from *tawɨ.

SUA *tawɨ "sun"

Corachol-Nahuan *tawe

Tara-guarijío: Wr tawé 'day'; Tr ŕawé ‘day’

Cahitan: My taáwa(ri) 'day'

Ópatan: Eu távi/táve/táwi 'día, sol'

In Tara-Cahitan/"Sonoran" we also find a short root *ta'a: Lionnet reconstructs: #267 *ta, "sol". - (Cahitan taá'а; Guarijío tahá) Stubbs reconstructs: #2230b. *ta’a / *ta- "(day)light, sun" (Yaqui taa’a "sun"; Mayotaa’a "sol"; Raramuri ra-, ta-, ra-tá "daylight, sun, brightness".)

NUA:

Hopi: taawa "sun, day"; Hopi taavi "sunshine, sunlight"
