Mistake: Wrong Case After Verbs

English has one object case, so an English speaker treats every object the same: whatever the verb acts on simply follows it, unchanged. Croatian verbs are pickier. Most take the accusative, but a stubborn minority govern a different case — dative, genitive, or instrumental — and the choice is lexical: it lives in the verb itself, not in the logic of the sentence. The trap is that these verbs feel like they take a plain object in English ("I help you," "I fear the dog"), so the learner reaches for the accusative every time. This page lists the worst offenders as wrong→right pairs, with the governed case named on each. The full system is on the verb government overview.

Verbs that take the DATIVE

A handful of common verbs govern the dative — the case of the recipient or beneficiary. The English translation hides this completely: "help you," "trust you," "congratulate you" all look like direct objects. In Croatian the person is the one to whom help, trust, or congratulation is directed, so the dative is logical once you see it — but you have to learn the verb as a dative verb up front.

pomoći (to help) + dative. You help to someone:

vjerovati (to believe / trust) + dative. You give your trust to someone:

čestitati (to congratulate) + dative. You offer congratulations to someone:

Verbs that take the GENITIVE

Several reflexive verbs in -ti se govern the genitive. The reflexive se is the clue that something is different from a plain transitive verb; the genitive object names what the feeling is about or of.

bojati se (to be afraid) + genitive. You are afraid of something:

sjećati se (to remember) + genitive. You hold the memory of something:

The same genitive government turns up in plašiti se (to be scared of), stidjeti se (to be ashamed of), and odreći se (to renounce). The pattern — reflexive feeling-verb + genitive — is worth memorising as a family.

Verbs that take the INSTRUMENTAL

A smaller group governs the instrumental — historically "by means of" or "occupied with." The English object again looks plain, but Croatian frames the activity as something you are engaged with.

baviti se (to do / be occupied with, as a job or hobby) + instrumental:

baviti se with a profession works the same way:

The same instrumental government appears with upravljati (to manage / steer) and služiti se (to make use of): upravljati timom (to manage a team), služiti se rječnikom (to use a dictionary).

There is no shortcut — these are lexical facts

Be honest with yourself: there is no rule that predicts, from meaning alone, that pomoći takes the dative while trebati (in its modern personal use) takes the accusative. The case is a property of the verb, learned with the verb, the way you learn an irregular plural. The good news is the list is short and the verbs are high-frequency, so a few weeks of use cements them. Group them by case and rehearse the case inside the verb's entry: pomoći + DAT, bojati se + GEN, baviti se + INSTR.

Key Takeaways

• Dative verbs: pomoći (help), vjerovati (believe/trust), čestitati (congratulate) — the person is dative (pomažem ti, vjerujem ti, čestitam ti), not accusative. Insert a mental "to."
• Genitive verbs (often reflexive feeling-verbs): bojati se (fear), sjećati se (remember), stidjeti se (be ashamed) — the object is genitive (bojim se psa, sjećam se tog dana).
• Instrumental verbs: baviti se (be occupied with), upravljati (manage), služiti se (use) — the object is instrumental (bavim se sportom).
• The governed case is a lexical fact, not derivable from meaning — learn it as part of the verb. There is no shortcut, but the list is short and frequent.
• The underlying error is always the same: English's single object case makes you default to the accusative. Override that reflex verb by verb.
