Frances Karttunen: 

TŌNALCĒUHYOH shadow, place in the shade / sombra (T) [(2)Tp.242]. Because of word-final vowel shortening and the general loss of word-final glottal stop in T, it cannot be determined if this ends in –YŌ or -YOH, but the fact that it does not take an absolutive suffix is evidence in favor of –YOH. See TŌNALCĒHU(I).
