"Power is not my goal."
Translation:Władza nie jest moim celem.
Sorry, Jellei, but can you please explain why you state that 'my goal' stays in the Instrumental case when Stewart156051 wanted to say 'My goal is not power'? I would have thought that 'My goal' is just the subject of the sentence and that it stays in the nominative case, with 'power' being in the instrumental (because of using 'jest'), hence władzą. Many thanks.
I believe that the easiest way to find out what can take Instrumental is to see if you could logically put 'a/an' before it.
Power is a goal. Yup, that works. The goal is a power. That doesn't seem to make much sense. Therefore "moc" can't take Instrumental here.
"Invisibility is a power" (superpower) could work, right? But not "Power is an invisibility". So here only "moc" could take Instrumental.
Maybe it's not much, but I wrote something about it in Part 1,5 here: https://www.duolingo.com/comment/16373167
