Conjugation

Note: This verb has been variously described by Young (1987) as a ∅-classifier/yii-imperfective, and Young (1992) as a ∅-classifier/yii-perfective.

It is here rather described as a d-classifier/yii-perfective, which is the only combination that accounts for both the -iis ending in the 1sg (as per the d-classifier; the ∅- classifier would give -ii) and the -ini ending in the 2sg (as per the yii-perfective; the yii-imperfective would give -ii).
