-aato

• -kaato, -yaato (allomorphs)

Seemingly from -a (nonpast suffix) +‎ -to (plural verb suffix); however, compare -ato (“recent past imperfective non-third-person plural suffix”), apparently formed from the same morphemes but without the unexpected vowel lengthening. According to Cáceres, it is unclear if this suffix in fact presents a long vowel, or if it rather has a geminated consonant after the vowel, and more study is needed to determine if perhaps it is not formed with -to but a different plural suffix specific to the nonpast tense.

• IPA^(key): [-aːto]

-aato

1. Forms the plural of the nonpast tense.

This suffix can cause syllable reduction. The suffix takes the form -kaato when the preceding syllable is reducible and has an onset of k, -yaato when the preceding syllable ends in i, and -aato in other contexts.
