Why in this sentence with 'jest' not one of the two words 'compared' is instrumental ?
From the grammar I have seen so far I would conclude:
Jakie (Nom. Sg Neut) To twoje pytanie (Nom Sg Neut)
or with 'jest' one of the following options:
1- Jakie (Nom sg n) jest twoim pytaniem. (instr. sg n)
2- Jakim (instr sg n) jest twoje pytanie.
This apparently is not happening. Why ?
Imagine that the answer to this question is "strange". "Twoje pytanie jest dziwne" = "Your question is strange". And you can see, that such a sentence will simply take Nominative for 'strange', as it is not a noun phrase but just an adjective.
And thus, the question itself also takes Nominative for "jakie".
I'm a super-novice (not particularly super, but especially novice), and the above all comments make sense to me. Co/Jakie=What requiring a noun/adjective answer.
There are undoubtedly exceptions (as with most languages), and I understand asking 'where' when the answer is one of a displayed list.
Presently I'm chuffed, i pronounced "Dzien dobre" close enough for the maid of my hotel room to know what i meant, but amusingly/unusually enough for her to chuckle.
Dzieki, thank you all
