Usage notes
When this suffix is attached to intransitive verb stems, they do not bear person markers. Consonant-initial stems experience palatalization of their initial consonants, and, if a stem begins with two consonants, this suffix takes the form of a circumfix instead of its ordinary shape.

With transitive verb stems, on the other hand, person markers are present and agree with the patient argument of the verb; first- and second-person markers are series I, while the third-person marker is (or one of its allomorphs), which is also found with other negative verb forms.

The suffix form is found after stems that end in. This suffix can also cause reduction of the preceding syllable.
