Koji in the Cases

Level 4

Koji changes its ending like an adjective, depending on its role in its own clause.

accusativekoji / kojeg(a)kojukoje

The masculine accusative is kojeg for people and animals, and koji for things. The forms with -a or -u at the end are longer variants of the same word.

In the plural, the genitive is kojih and the dative, locative and instrumental are kojima.

Example: Knjiga koju čitam je stara. The word koju is feminine because of knjiga, and accusative because it is the object of čitam.

After a preposition, the preposition decides the case: grad u kojem živim, žena s kojom razgovaram.
