MICTLĀN-TLI the realm of the dead / inferno o en el infierno o al infierno (M), infierno, purgatorio (T) This is consistently attested across sources with a long vowel in the second syllable. M gives it both with and without the absolutive suffix. It is more common without and does not take the suffix when used as a locative expression. See MIQU(I), -TLĀN.
