Still tense is an absolute tense carrying the presupposition that an event or state held before the moment of utterance.
In positive declarative clauses, still tense asserts that the event or state holds at the moment of utterance.
(Luganda)
The affix -kya expresses still tense, as in the utterance mu-kya-tudde ‘you still sit’.
