"The tall building is a hospital."

Translation: A magas épület egy kórház.

[Daniel640094]

How about without the "egy"?

I wrote: "A magas épület egy kórház van", is it wrong or correct?

Wrong, when you describe something, you don't need to use "van" but hey, at least you put it in the correct place because that's where it would be if we used "van" in third person singular. :D
