I just want to congratulate all those who have made it this far and can understand this sentence because it's fairly complex and idiomatic! The subject of the sentence is in the genitive case, connecting to word three words down. That word is singular though semantically plural. The verb reflects neither the object nor the subject. You can do a lot already! :D
Thanks for the congratulations but I don't think that I merit them yet.
You say that the subject is in genitive case, which I still do not understand. My thought was that the subject is "kapısı", which is possessed (hence the suffix sı) by something (in genitive case), but is not in genitive itself.
So it still does not make sense for me ...
Thank you for your reply, also for the German sentence (wich got deleted, but I received it as a mail, as I watch this discussion).
In "the house's door(s)" as well as in "des Hauses Türen" the subject are the doors, not the house. As far as I understood it until now, in Turkish (as in English or German) the "nominative case" (used for the subject of the sentence) does not get a case ending.
The doors do have an ending here (-sı), but this is not a case ending, but only a possessive ending, so kapısı - as far as I understand - still is in "nominative" case and the subject of the sentence.
