Principal English Translation:

Frances Karttunen:
-TZĀLAN. (postposition). between, among / entre algunos, o por medio dellos (M) This is abundantly attested in C with the vowel of the first syllable long and that of the second syllable never marked long. T has long vowels in both syllables, but the final N is missing. Z has both vowels long. See TZĀLAN-TLI.
