Frances Karttunen:
TLAHYELOĀ vt to soil something / ensuciar algo (M) [(1)Rp.149]. R places the diacritic on the wrong syllable. It appears on the second, but it belongs on the first. See TLAHYEL-LI. Frances Karttunen, An Analytical Dictionary of Nahuatl (Norman: University of Oklahoma Press, 1992), 271.
