CUĀYECACHOĀ vrefl to nod one’s head / cabecea (T) [(3)Tp.148]. Thes second element here may be derived from YAC(A)-TL ‘nose, ridge summit’ or may conceivably be a reduction of ĀYACACHOĀ ‘to play the rattle,’ namely, for one’s head to bob up and down like a rattle. See CUĀ(I)-TL. Frances Karttunen, An Analytical Dictionary of Nahuatl (Norman: University of Oklahoma Press, 1992), 67.
