My professor asked us to formulate the phrase using this:

Ich - geben - zurück - sie (die Bücher) - Der Bibliothek

I wrote:

Ich gebe sie dem Bibliothek zurück

But he shows the answer as

Ich gebe sie der Bibliothek zurück

I don't understand why in this case, since I am returning something to the library, it shouldn't be in dativ case. Is it because of zurück? I am not entirely sure that the sentence makes sense to me.

    @BjörnFriedrich "The noun Bibliothek is female. Therefore, the genitive is der Bibliothek". Why "genitive"? This question deals with dative.

    Following our policy, you should always describe what you tried to answer the question yourself including what you do or don't understand. In this case, if you would have looked up the Dativ of "Bibliothek", you would have found that Bibliothek is "feminin" and that the Dativ is indeed "der Bibliothek".

  • @Nico, my mistake. I thought it was asked for Bücher der Bibliothek (the books from the library). Apr 16, 2020 at 9:54
  • @BjörnFriedrich I only remarked it in order for the asker not to get confused.

Your Answer is not wrong because of the case you used but because the library is a feminine word Die Bibliothek.

The dativ of Die Bibliothek is Der Bibliothek.
