Morati ("must, have to") is the obligation modal — the verb behind Moram ići ("I have to go"), Moraš to vidjeti ("You have to see this"), and the polite Moralo bi se ("One ought to…"). It is a perfectly regular a-class verb in the present, which makes it easy to conjugate; the difficulty is entirely semantic, in one place: the negative. In Croatian, ne moram means "I don't have to" — the absence of obligation — and never "I mustn't". For "mustn't / not allowed", Croatian switches to a completely different verb, ne smijem. Get that contrast right and morati holds no further surprises.
Aspect
Morati is imperfective and has no aspectual partner. As a modal expressing a standing obligation, it describes an ongoing relation between you and a required action, not a bounded event — so the idea of a "perfective morati" does not exist. The action morati governs can be of either aspect (moram napisati = perfective complement; moram pisati = imperfective complement); for how a modal's complement chooses aspect, see Aspect with Phase and Modal Verbs.
Present tense
Regular a-class: stem mora- + -m, -š, -∅, -mo, -te, -ju. The theme vowel -a- is visible throughout, including the 3rd-person plural moraju.
| Person | Form | Meaning |
|---|---|---|
| ja | moram | I must / have to |
| ti | moraš | you must |
| on/ona/ono | mora | he/she/it must |
| mi | moramo | we must |
| vi | morate | you must |
| oni/one/ona | moraju | they must |
Moram ići, kasnim na posao.
I have to go, I'm late for work.
Moraš probati ovaj kolač, fenomenalan je.
You have to try this cake, it's phenomenal.
Djeca moraju biti u krevetu do devet.
The kids have to be in bed by nine.
The l-participle
Regular for an -ati verb: stem mora- + the l-participle endings.
| Gender / number | Form |
|---|---|
| masculine singular | morao |
| feminine singular | morala |
| neuter singular | moralo |
| masculine plural | morali |
| feminine plural | morale |
| neuter plural | morala |
The masculine morao shows the vocalised -l (mora- + -l → morao); the feminine morala and the rest keep the -l- visible.
Perfect tense (perfekt)
Clitic biti + l-participle. In the past, morati means "had to / was forced to".
| Person | Masculine subject | Feminine subject |
|---|---|---|
| ja | morao sam | morala sam |
| ti | morao si | morala si |
| on / ona | morao je | morala je |
| mi | morali smo | morale smo |
| vi | morali ste | morale ste |
| oni / one | morali su | morale su |
Morali smo otkazati put zbog bolesti.
We had to cancel the trip because of illness.
Morala sam čekati dva sata u redu.
I had to wait two hours in line. — feminine speaker.
Future I (futur prvi)
The infinitive morati ends in -ti, so it drops its final -i before the future clitic: morat ću.
| Person | Infinitive first | Clitic first |
|---|---|---|
| ja | morat ću | … ću morati |
| ti | morat ćeš | … ćeš morati |
| on/ona/ono | morat će | … će morati |
| mi | morat ćemo | … ćemo morati |
| vi | morat ćete | … ćete morati |
| oni/one/ona | morat će | … će morati |
Morat ćeš se ispričati, nemaš izbora.
You'll have to apologise, you've got no choice.
Imperative
Morati has no natural imperative. You cannot command someone "must!" — the obligation is already a command. Where English might say "you must go now", Croatian uses the plain present Moraš ići as a forceful statement, or rephrases with a direct imperative of the main verb (Idi! "Go!").
Moraš odmah krenuti ako želiš stići na vrijeme.
You must leave right now if you want to make it on time. — present does the work an imperative can't.
Conditional I (kondicional prvi)
The conditional softens obligation into advice — "ought to / should". bih-clitics + l-participle.
| Person | Form (masc.) |
|---|---|
| ja | morao bih |
| ti | morao bi |
| on/ona/ono | morao/morala/moralo bi |
| mi | morali bismo |
| vi | morali biste |
| oni/one/ona | morali bi |
Morao bih više vježbati, ali nikad nemam vremena.
I ought to exercise more, but I never have time. — softened, masculine speaker.
Morala bi mu to reći u lice, ne preko poruke.
You should tell him that to his face, not over text. — softened, to a woman.
The impersonal moralo bi se expresses a general "one ought to".
Tu se nešto moralo poduzeti davno.
Something ought to have been done about this long ago. — impersonal 'moralo se'.
Other forms
As a modal that takes an infinitive complement, morati has no passive participle. The present verbal adverb morajući ("[while] having to") is grammatically possible but rare; you will almost never need it.
Key uses and government
1. Obligation: morati + infinitive
The core construction is morati + a bare infinitive. In casual speech you will also hear morati + da + present, but the western standard prefers the infinitive (see da + present vs the Infinitive).
Moram još kupiti kruh i mlijeko.
I still have to buy bread and milk.
Moramo se naći do kraja tjedna.
We have to meet by the end of the week.
2. The negative trap: ne moram ≠ "mustn't"
This is the single most important point on the page. Ne moram removes the obligation: "I don't have to, I'm not obliged to". It is not a prohibition. To say "you mustn't / you're not allowed to", Croatian uses ne smiješ (the negative of smjeti, the permission modal).
Sutra je neradni dan, ne moram rano ustati.
Tomorrow's a day off, I don't have to get up early. — absence of obligation.
Ne moraš sve znati, samo pitaj ako zapneš.
You don't have to know everything, just ask if you get stuck.
Compare the two negatives side by side — they mean opposite things:
Ne moraš doći. Ali ne smiješ doći prekasno.
You don't have to come. But you mustn't come too late. — 'ne moraš' = no obligation; 'ne smiješ' = prohibition.
For the full obligation system, see Obligation: morati, trebati, valja; for the permission verb, smjeti.
3. morati vs trebati for advice
Both can render "should", but morati in the conditional is stronger ("really ought to / must"), while trebati is the softer, more neutral "should". When in doubt about advice strength, trebao bih is gentler than morao bih.
Trebao bi se odmoriti, a zapravo bi morao otići doktoru.
You should rest — and honestly you really ought to see a doctor. — 'trebati' softer, 'morati' stronger.
Common Mistakes
❌ Ne moraš pušiti ovdje.
Meaning error — this says 'you don't have to smoke here'. For a prohibition use 'ne smiješ'.
✅ Ne smiješ pušiti ovdje.
You mustn't smoke here. / Smoking isn't allowed here.
❌ Moram da idem odmah.
Substandard in the western norm — 'morati' prefers a bare infinitive: 'Moram ići'.
✅ Moram ići odmah.
I have to go right away.
❌ Oni more raditi vikendom.
Wrong conjugation — 'morati' is a-class: the 3pl is 'moraju', not '*more'.
✅ Oni moraju raditi vikendom.
They have to work on weekends.
❌ Ona je morao otkazati sastanak.
Agreement error — the l-participle must match a feminine subject: 'morala'.
✅ Ona je morala otkazati sastanak.
She had to cancel the meeting.
❌ Moraju ću ostati duže.
Form error — the future combines the infinitive with the clitic: 'morat ću ostati'.
✅ Morat ću ostati duže.
I'll have to stay longer.
Key Takeaways
- Morati is imperfective with no aspectual pair; it is a regular a-class verb: moram, moraš, mora, moramo, morate, moraju.
- It takes a bare infinitive (Moram ići); the da-clause is colloquial/eastern.
- The big trap: ne moram = "don't have to" (no obligation), never "mustn't". Prohibition is ne smiješ.
- The conditional morao/morala bih softens to "ought to / should" — but is still stronger than trebao/trebala bih.
- Future morat ću; past morao/morala sam ("had to"); no real imperative.
