Dovere (must, to have to, to owe) is the third Italian modal verb, completing the trio with potere and volere. It expresses obligation, necessity, strong probability, and — used as a non-modal lexical verb with a direct object — the act of owing money or owing someone something. Like its modal siblings, dovere takes a bare infinitive, lacks an imperative, and follows the auxiliary-matching rule in compound tenses.
The paradigm is irregular and offers an unusual feature: parallel forms in the present and present subjunctive. Devo and debbo both mean "I must"; devono and debbono both mean "they must." The devo/devono forms dominate spoken Italian almost entirely; the debbo/debbono forms survive in formal writing and bureaucratic prose. Both are correct — your job as a learner is to recognise both and produce the more common ones.
The compound avrei dovuto + infinitive is one of the most useful constructions in Italian: it is the standard equivalent of English "I should have…" — counterfactual past obligation. Avrei dovuto chiamare ("I should have called") is a sentence you'll use weekly.
Indicativo presente
| Person | Form | Variant |
|---|---|---|
| io | devo | debbo |
| tu | devi | — |
| lui / lei / Lei | deve | — |
| noi | dobbiamo | — |
| voi | dovete | — |
| loro | devono | debbono |
In speech and ordinary writing, devo and devono are by far the most common forms. The debbo/debbono variants persist in formal registers — official correspondence, legal language, academic prose — and in some literary or older texts. Recognising both is enough; producing devo/devono is the safe default.
The noi form dobbiamo has the same double-b consonant cluster as abbiamo (from avere) — a recurring pattern in irregular noi forms. The diphthong shifts: dev- under stress (devo, devi, deve, devono), dob- when the noi/voi forms shift the stress (dobbiamo, dovete).
Devo finire questo lavoro entro venerdì.
I have to finish this work by Friday.
Devi assolutamente provare il tiramisù di mia nonna.
You absolutely have to try my grandmother's tiramisù.
Mio fratello deve studiare per l'esame di domani.

Imperfetto
| Person | Form |
|---|---|
| io | dovevo |
| tu | dovevi |
| lui / lei / Lei | doveva |
| noi | dovevamo |
| voi | dovevate |
| loro | dovevano |
The imperfetto is fully regular and built on the predictable stem dov-. It expresses past obligation as background or ongoing state: "I had to," "I was supposed to," "I used to have to."
A useful nuance: dovevo + infinitive often translates English "I was supposed to" — an obligation that was set up but may or may not have been fulfilled: Dovevo chiamarti ieri, scusa ("I was supposed to call you yesterday, sorry"). Pair this with the passato prossimo ho dovuto for the action that actually happened.
Dovevo svegliarmi presto, ma ho dormito troppo.
I was supposed to wake up early, but I overslept.
Da ragazzi dovevamo aiutare in cucina ogni domenica.
As kids we had to help in the kitchen every Sunday.
Passato remoto
| Person | Form |
|---|---|
| io | dovei / dovetti |
| tu | dovesti |
| lui / lei / Lei | dové / dovette |
| noi | dovemmo |
| voi | doveste |
| loro | doverono / dovettero |
Like potere, dovere offers two parallel sets in the io, lui, and loro forms — a "weak" set in -ei/-é/-erono and a "strong" set in -etti/-ette/-ettero. The -etti forms are slightly more common in literary use. Note the acute accent on dové (chiuso, like poté) — both verbs follow the same accent rule on stressed final e.
Dovette aspettare due ore prima di essere ricevuto.
He had to wait two hours before being seen.
Futuro semplice
| Person | Form |
|---|---|
| io | dovrò |
| tu | dovrai |
| lui / lei / Lei | dovrà |
| noi | dovremo |
| voi | dovrete |
| loro | dovranno |
The future stem is contracted from dover- to dovr-, the same drop of unstressed e you see in avrò, potrò, saprò. Don't write doverò.
The future of dovere doubles as strong probability or inference about the present: Dovrà essere stanco doesn't necessarily mean "he will have to be tired" — more often it means "he must be tired" (a confident guess). This conjectural use is identical to avrà, sarà, potrà.
Dovrò svegliarmi alle cinque per prendere il volo.
I'll have to get up at five to catch the flight.
Non risponde nessuno — dovranno essere già usciti.
Nobody's answering — they must have already gone out.
Condizionale presente
| Person | Form |
|---|---|
| io | dovrei |
| tu | dovresti |
| lui / lei / Lei | dovrebbe |
| noi | dovremmo |
| voi | dovreste |
| loro | dovrebbero |
The conditional of dovere is the standard Italian translation of English "should" — softer than the indicative devo (which is "I have to"). Dovrei is the difference between "I have to call my mother" and "I should call my mother" — between a hard obligation and an advisable course of action.
As always, the double m in dovremmo distinguishes the conditional from the future dovremo. Single m = will have to; double m = should.
Dovresti riposarti un po', sembri esausto.
You should rest a bit, you look exhausted.
Dovremmo partire prima delle sette per evitare il traffico.
We should leave before seven to avoid traffic.
Dovrebbero arrivare a momenti.
They should be arriving any moment now.
Congiuntivo presente
| Person | Form | Variant |
|---|---|---|
| (che) io | debba | deva |
| (che) tu | debba | deva |
| (che) lui / lei | debba | deva |
| (che) noi | dobbiamo | — |
| (che) voi | dobbiate | — |
| (che) loro | debbano | devano |
Both debba/debbano and deva/devano are correct, and both are widely used in writing. In speech, debba is somewhat more common; in formal prose, debba is the standard literary choice. Pick one variant and use it consistently within a single text.
The three singular forms collapse into debba (or deva) — context and explicit pronouns disambiguate.
Penso che tu debba parlargli direttamente.
I think you should talk to him directly.
Non credo che debbano preoccuparsi così tanto.
I don't think they need to worry so much.
Congiuntivo imperfetto
| Person | Form |
|---|---|
| (che) io | dovessi |
| (che) tu | dovessi |
| (che) lui / lei | dovesse |
| (che) noi | dovessimo |
| (che) voi | doveste |
| (che) loro | dovessero |
These forms appear in hypotheticals with se: se dovessi ("if I had to / if I should"). The structure Se dovessi… + conditional is the polite hedging formula par excellence: Se dovessi scegliere, prenderei il rosso ("If I had to choose, I'd take the red one").
Se dovessi tornare indietro, farei tutto uguale.
If I had to do it over again, I'd do everything the same.
Pensavo che doveste partire stamattina.
I thought you guys had to leave this morning.
Imperativo
Like potere and volere, dovere lacks an imperative. You cannot command someone to "have to" — obligation can be created by direct command of the underlying verb (Vai! "Go!"), or by stating the obligation in the indicative (Devi andare "You must go"), but the modal itself can't be ordered.
Forme non finite
| Form | Italian |
|---|---|
| Infinito presente | dovere |
| Infinito passato | avere dovuto / essere dovuto/a |
| Gerundio presente | dovendo |
| Gerundio passato | avendo dovuto / essendo dovuto/a |
| Participio passato | dovuto |
The participio passato dovuto is regular. As a noun, il dovuto means "what is owed" or "what is due" — a useful crossover from the verbal to the nominal sense.
Compound tenses and the modal auxiliary rule
When dovere is used as a modal (followed by an infinitive), the prescriptive rule is the same as for potere and volere: the auxiliary matches the infinitive. With essere, the past participle dovuto agrees with the subject in gender and number.
| Underlying verb | Compound with dovere | English |
|---|---|---|
| lavorare (avere) | ho dovuto lavorare | I had to work |
| partire (essere) | sono dovuto/a partire | I had to leave |
| finire (avere) | ho dovuto finire | I had to finish |
| uscire (essere) | sono dovuto/a uscire | I had to go out |
When dovere is used non-modally with a direct object (meaning "to owe"), the auxiliary is always avere: Ti devo cento euro ("I owe you a hundred euros"), Gli devo un favore ("I owe him a favour"). In this lexical sense the verb is most commonly used in the presente or imperfetto; the passato prossimo gli ho dovuto un favore is grammatical but unusual in everyday speech.
Ho dovuto rifare il lavoro da capo.
I had to redo the work from scratch.
Maria è dovuta uscire all'improvviso.
Maria had to leave suddenly. (essere because of uscire)
Avrei dovuto: should have
The condizionale passato of dovere (avrei dovuto / sarei dovuto) + infinitive is the standard Italian way to express counterfactual past obligation — English "I should have." This is one of the most useful constructions in the language.
| Person | With avere-verb | With essere-verb |
|---|---|---|
| io | avrei dovuto | sarei dovuto/a |
| tu | avresti dovuto | saresti dovuto/a |
| lui / lei | avrebbe dovuto | sarebbe dovuto/a |
| noi | avremmo dovuto | saremmo dovuti/e |
| voi | avreste dovuto | sareste dovuti/e |
| loro | avrebbero dovuto | sarebbero dovuti/e |
Avrei dovuto chiamarti prima, scusami.
I should have called you sooner, I'm sorry.
Saremmo dovuti andare in vacanza l'anno scorso.
We should have gone on holiday last year.
Non avresti dovuto dirgli quella cosa.
You shouldn't have told him that.
Compare with dovevo, which expresses past obligation as background ("I was supposed to") rather than retrospective regret ("I should have"): Dovevo chiamarti = "I was supposed to call you (and may or may not have)"; Avrei dovuto chiamarti = "I should have called you (and didn't)."
Common mistakes
❌ Devo di andare a casa.
Incorrect — modals take a bare infinitive, no preposition.
✅ Devo andare a casa.
Correct — direct infinitive after dovere.
❌ Penso che lui deve studiare di più.
Incorrect — penso che triggers the subjunctive.
✅ Penso che lui debba studiare di più.
Correct — debba is the congiuntivo presente.
❌ Avrei dovuto a chiamarti.
Incorrect — no preposition between dovuto and the infinitive.
✅ Avrei dovuto chiamarti.
Correct — bare infinitive after dovuto.
❌ Domani noi dovremmo andare al lavoro, è obbligatorio.
Incorrect for stating a hard obligation — dovremmo (double m) is the conditional 'we should'.
✅ Domani noi dovremo andare al lavoro, è obbligatorio.
Correct — dovremo (single m) is the simple future 'we will have to'.
❌ Ho dovuto andato al supermercato.
Incorrect — after a modal you use the infinitive, not the past participle.
✅ Ho dovuto andare al supermercato.
Correct — andare (infinitive) after ho dovuto.
Key takeaways
Dovere is the modal of obligation, necessity, and strong probability — and, as a non-modal lexical verb, the verb of owing. Memorise the presente first — devo, devi, deve, dobbiamo, dovete, devono — accepting that the parallel debbo/debbono forms exist but are formal-only. Then drill the conditional dovrei (= "I should") and the counterfactual avrei dovuto (= "I should have").
Three points to internalise:
Dovrei beats devo for soft suggestions. Devi smettere di fumare ("you must quit smoking") is a hard demand; Dovresti smettere di fumare ("you should quit smoking") is friendly advice. The conditional is the polite default.
Avrei dovuto + infinitive = "should have." This counterfactual past is one of the most useful constructions in Italian. Memorise it as a unit.
Modal auxiliary rule applies: in compound tenses, dovere takes whichever auxiliary the underlying infinitive takes — ho dovuto lavorare but sono dovuto/a partire. With essere, the participle agrees with the subject.
Once dovere is solid, the trio of potere, volere, and dovere is complete — together they generate an enormous fraction of all real-world Italian sentences, and their conditionals (potrei, vorrei, dovrei) are the politeness backbone of the language.
