Frances Karttunen: 

TLACEHCĒUHYOH cool weather, shade / fresco (clima), sombra (T) [(1)Tp.235]. Because of general word-final vowel shortening and the loss of final glottal stop in T, it cannot be determined whether this ends in –YOH or –YŌ, but the absence of an absolutive suffix is evidence for –YOH. See CĒHU(I).
