Uto-Aztecan language (4)
I believe the answer is:
hopi
'uto-aztecan language' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hopi that I've seen before include "Arizonan Pueblo Indian" , "Arizona inhabitant" , "North American Indian people" , "Language" , "Member of a Pueblo Indian people of northeastern Arizona" .)
