CUĀCUAUHPIY(A) pret: -PIX ~ -PIX to herd cattle / cuida bueyes (T) [(4)Tp.122,231]. CUĀCUAUH here is apparently a truncation of CUĀCUAHUEH ‘animal with horns.’ The long-vowel variant preterit form is not directly attested but is established for component PIY(A). See CUĀCUAHU(I)-TL, PIY(A). Frances Karttunen, An Analytical Dictionary of Nahuatl (Norman: University of Oklahoma Press, 1992), 57.
