Questions & Answers about Marina je blizu našeg hotela.
Je is the 3rd person singular present tense of biti (to be).
So in this sentence, je means is.
- Marina je ... = Marina is ...
- Hotel je ... = The hotel is ...
It is a very common little word in Croatian.
Because blizu normally goes with the genitive case.
So after blizu (near), the noun phrase changes form:
- naš hotel = nominative
- našeg hotela = genitive
That is why Croatian says:
- blizu našeg hotela
not
- blizu naš hotel
English does not show this kind of case change, but Croatian does.
