Questions & Answers about Haluatko jättää tämän muutoksen pysyväksi?
Why does the adjective pysyvä (permanent) take the translative ending -ksi in this sentence?
The verb jättää (to leave) requires the translative case to express the resulting state or condition of the object. You aren't just leaving a permanent change behind; you are actively deciding to leave the change as permanent.
The current lesson also covers jäädä (to remain). Could I use jäädä instead of jättää here?
No, because you need a transitive verb here. Jättää means you are doing the action to an object (you are leaving the change permanent). Jäädä is intransitive and applies to the subject itself. If you wanted to use jäädä, the sentence structure would have to change entirely, for example: Jääkö tämä muutos pysyväksi? (Will this change remain permanent?).
Why are tämän and muutoksen in the genitive case rather than the partitive?
They form the total object of the verb jättää. You are talking about leaving this one specific, complete change in a permanent state, so it takes the genitive-looking accusative case. If the action were incomplete or the object was an uncountable mass, you would use the partitive.
