kojega

"Which" or "whom" (masculine singular genitive or accusative form).

The word 'kojega' is used here as a relative pronoun in its accusative form, linking 'prijatelj' (friend) as an object of the verb 'poznajem' (I know).

Ovo je prijatelj kojega poznavam od djetinjstva.

This is a friend whom I have known since childhood.

Here, 'kojega' serves as a relative pronoun referring back to 'čovjeka' (man) and acts as the object of the action 'sreli' (encountered).

She met the man whom we encountered yesterday.

In this sentence, 'kojega' is functioning as part of a relative clause indicating possession, connecting 'problem' with the action 'trebamo riješiti' (need to get rid of).

To je problem kojega se trebamo riješiti.

That is a problem of which we need to get rid.
