bolnicu

In a sentence

• Moram posjetiti bolnicu zbog pregleda.

  I need to visit the hospital for a check-up.

  Here, 'bolnicu' is in the accusative case, functioning as the direct object of the verb 'posjetiti' (to visit).

• Vidjela sam bolnicu s prozora autobusa.

  I saw the hospital from the bus window.

  In this sentence, 'bolnicu' again takes the accusative case, as it is the direct object of 'vidjela' (saw).

• Parkirali smo se blizu bolnice.

  We parked near the hospital.

  For this usage, 'bolnice' changes to the genitive case as it follows the preposition 'blizu' (near).
