Questions & Answers about Lijek koji doktor daje je dobar.

Why is it koji and not kojeg?

Because the relative pronoun is the direct object of the verb in the relative clause, and it refers to an inanimate masculine noun. For masculine inanimate nouns, the accusative singular has the same form as the nominative: koji. If the antecedent were masculine animate (e.g., a man), the accusative would be kojeg.

• Inanimate: Lijek koji doktor daje … (medicine that the doctor gives)
• Animate: Čovjek kojeg doktor vidi … (the man whom the doctor sees)

What case is koji here, and what does it agree with?

• Case: Accusative singular (object of daje in the relative clause).
• Agreement: It agrees in gender and number with its antecedent lijek (masculine singular). The case is determined by its function in the relative clause (object).

Why is there no word for “the” (as in “the medicine”)?

Croatian has no articles. Definiteness (“the”) is understood from context, word order, and modifiers. If you need to make it explicit, you can add a demonstrative: Taj lijek koji doktor daje je dobar (That medicine … is good).

Why is je placed after the whole subject phrase and not right after Lijek?
