oni

In a sentence

• Oni idu u školu svaki dan.

  They go to school every day.

  Here, 'oni' is used as a pronoun referring to a group of males or a mixed group in the nominative case serving as the subject of the verb 'idu' (go).

• Jesi li vidio one ljude tamo?

  Did you see those people over there?

  In this sentence, 'one' is a form of 'oni' used as a demonstrative pronoun referring to 'ljude' (people), in the accusative case since it is the object of the verb 'vidjeti' (to see).

• Slatke su, zar ne? Oni su naši psi.

  They are sweet, aren’t they? They are our dogs.

  Here, 'oni' is used again as a pronoun in the nominative case, referring to a group of entities (in this case 'psi', dogs) introduced in the previous sentence.
