Up to now, I've been forming passive statements like this:
Isan a napysh.
Eat dir-obj cheese.
The cheese is being eaten.
But now I've decided to handle it like this:
(Ni) wisannya sy apysh.
(Is) eating of cheese.
The cheese is being eaten. / There is an eating of cheese.
This feels more natural and also solves a problem I had with tense marking passive statements. Since the gerund is the subject, it can mark the tense of the statement.
(Ni) wisannia sy apysh.
(Is) eating(past) of cheese(pres).
The cheese was being eaten. / There was an eating of cheese.
The object (cheese in this case) is indirect, but thanks to another change I recently made, it too can be tense marked, for aspectual functions.
(Ni) wisannya sy iapysh.
(Is) eating(pres) of cheese(past).
The cheese had been eaten. / There is an eating that had been of cheese.
