Learn Hardcore Croatian: Ona mora raditi ujutro. - She has to work in the morning.

Mora (from morati) expresses a strong obligation, very close to English must/have to. It suggests necessity or an external requirement. It’s stronger and more categorical than treba (need/should).

Why is it raditi and not radi after mora?

After modal verbs like morati, the main verb stays in the infinitive. So it’s mora raditi, not mora radi. Think: must + infinitive → must work.

Can I drop Ona and just say Mora raditi ujutro?

Yes. Croatian is a pro‑drop language; the subject pronoun is often omitted when context makes it clear. Using ona can add emphasis or clarify who you’re talking about.

Where can ujutro go in the sentence? Is the word order flexible?

Yes. Common options:

Ona mora raditi ujutro.
Mora raditi ujutro.
Ujutro ona mora raditi. (fronting time for emphasis) All are correct; end placement is neutral; fronting highlights the time.

Is ujutro one word? What about u jutro or ujutru?

Standard Croatian uses the single word ujutro (in the morning).
u jutro (two words) is not standard as a time adverb.
ujutru is common in Serbian/Bosnian; Croatians will understand it, but ujutro is the Croatian standard.

How do I say this morning, tomorrow morning, and every morning?

This morning: jutros
Tomorrow morning: sutra ujutro
Every morning: svakog jutra (also heard: svako jutro)

How do I say She doesn’t have to work in the morning?

Ona ne mora raditi ujutro.
Note: ne mora = doesn’t have to / isn’t required to.

How do I say She mustn’t work in the morning (it’s not allowed)?

Ona ne smije raditi ujutro.
Be careful: ne mora (doesn’t have to) ≠ ne smije (must not / may not).

How do I ask Does she have to work in the morning?

Three common ways:

Neutral/formal Croatian: Mora li ona raditi ujutro?
Colloquial (yes–no intonation): Ona mora raditi ujutro?
Regional/BCS: Da li ona mora raditi ujutro? (understood, but Mora li…? is the Croatian standard)

How is morati conjugated in the present?

ja moram
ti moraš
on/ona/ono mora
mi moramo
vi morate
oni/one/ona moraju
In the sentence, mora is 3rd person singular.

How do I put this in the past or future?

Past: Ona je morala raditi ujutro. (She had to work in the morning.)
Future: Ona će morati raditi ujutro. or Ona će morat(i) raditi ujutro.
Colloquial contracted future (very common in Croatian): Ona će morat raditi ujutro. / Morat će raditi ujutro.

Is there any aspect choice after morati? Why raditi and not a perfective like napraviti?

You choose aspect based on meaning:

mora raditi (imperfective) = must be working / must do work (ongoing/habitual action).
mora napraviti izvješće (perfective) = must complete/finish the report (a single, completed result).
With general work, raditi is the natural imperfective.

Is mora da radi ujutro correct?

That da-construction is characteristic of Serbian. Standard Croatian uses the bare infinitive after modals: mora raditi ujutro, not mora da radi.

What’s the difference between morati and trebati here?

morati = must/have to (strong, binding obligation): Ona mora raditi ujutro.
trebati = need/should (softer, more advisory): Ona treba raditi ujutro.
Croatian uses trebati + infinitive (no da).

Does anything change because the subject is feminine (ona)?

In the present, no: mora is the same for he/she/it. In the past, the participle agrees: Ona je morala…, On je morao…, Oni su morali….

Can raditi mean both work (at a job) and do?

Yes. raditi can mean:

to be at work / perform one’s job: raditi ujutro (work in the morning)
to do/make something, often paired with a noun: raditi projekt (work on a project).
For a completed result, switch to a perfective like napraviti or izraditi.
