(Y)EHYĒILHUITICA every three days / cada tres dias (C) [(2)Cf.19v,107r, (1)Rp.37]. In attestations of this construction with other numbers the reduplication is of the long vowel type, not the vowel glottal stop type. Perhaps the glottal stop here is a reflex of stem-final Y. R marks the glottal stop on the second syllable instead of the first. See (Y)ĒY(I), ILHUI-TL. Frances Karttunen, An Analytical Dictionary of Nahuatl (Norman: University of Oklahoma Press, 1992), 338.
