The suffixes -(a)bat and -in~-ing are considered progressive markers here (but see comments on Feature 49 "Tense-aspect systems").
Both progressive markers are distinct from the habitual markers oldei~orlas~ala, yusdu and from future marking. Unmarked rather than progressive verbs tend to be used to express present habitual meanings. Future is always expressed by distinct markers.
The progressive suffix -in~-ing does not occur with stative verbs. The suffix -(a)bat does with positionals like jidan (see Example 210), but maybe these should not be considered prototypical stative verbs. It does not occur with stative verbs meaning e.g. 'know', 'have'.
