Dovere — Must / To Have To

Overview

Dovere is one of Italian's three essential modal verbs, alongside potere (can) and volere (to want). It expresses obligation, necessity, and — in more advanced usage — probability. At the A1 level, you will use it constantly: "I have to study," "you must pay," "we need to leave."

Like all modal verbs in Italian, dovere is followed by an infinitive verb. You conjugate dovere to match the subject, and the action verb stays in its base form: Devo partire (I have to leave). This pattern — modal + infinitive — is the same structure English uses with "must" or "have to."

Dovere is irregular, so its present-tense forms do not follow the standard -ere verb pattern. The good news is that these forms are so common in everyday speech that they become second nature quickly.

How It Works

Present Tense Conjugation

Person	Italian	English
io	devo	I must / I have to
tu	devi	you must / you have to
lui / lei / Lei	deve	he/she must, you (formal) must
noi	dobbiamo	we must / we have to
voi	dovete	you (all) must / you have to
loro	devono	they must / they have to

Note: An older alternative for io is debbo, and for loro, debbono. You may encounter these in writing, but devo and devono are standard in modern Italian.

Usage: Obligation vs Necessity vs Probability

Dovere covers three main meanings:

1. Obligation / Duty — something you are required to do, often by rules, authority, or social expectation.

   • Devi fare i compiti. — You have to do your homework.

2. Necessity — something that needs to happen due to circumstances.

   • Dobbiamo comprare il latte. — We need to buy milk.

3. Probability / Assumption (more advanced) — expressing what is likely true.

   • Deve essere tardi. — It must be late (= it's probably late).

At A1, focus on meanings 1 and 2. You will recognize meaning 3 naturally as you progress.

Structure: Dovere + Infinitive

The pattern is always: conjugated dovere + infinitive verb.

Structure	Example	Meaning
devo + infinitive	Devo lavorare.	I have to work.
devi + infinitive	Devi studiare.	You have to study.
deve + infinitive	Deve partire.	He/she has to leave.
dobbiamo + infinitive	Dobbiamo mangiare.	We have to eat.
dovete + infinitive	Dovete ascoltare.	You all have to listen.
devono + infinitive	Devono dormire.	They have to sleep.

Negative Form

To say "must not" or "don't have to," place non before dovere:

• Non devo lavorare domani. — I don't have to work tomorrow.
• Non devi parlare. — You must not speak.

Common Mistakes

Forgetting the infinitive

• Wrong: Devo a lavorare.
• Right: Devo lavorare.
• Why: Unlike English "have to work," Italian uses no preposition. Dovere connects directly to the infinitive.

Confusing devo with devi

• Wrong: Io devi andare.
• Right: Io devo andare. (or simply Devo andare.)
• Why: Devo is first person (io), devi is second person (tu). Mix-ups happen because the forms sound similar.

Using dovere where volere is meant

• Wrong: Devo un gelato. (intending "I want an ice cream")
• Right: Voglio un gelato.
• Why: Dovere means obligation, not desire. Use volere for wanting something.

Double conjugation

• Wrong: Devo lavoro.
• Right: Devo lavorare.
• Why: Only dovere is conjugated. The second verb must remain in the infinitive form (-are, -ere, -ire).

Omitting "non" for negation

• Wrong: Devo no lavorare.
• Right: Non devo lavorare.
• Why: In Italian, non always comes before the conjugated verb, not after it.

Practice Tips

1. Build a "daily obligations" list. Each morning, write 5 sentences about what you have to do today using dovere: "Devo studiare," "Devo cucinare," "Devo telefonare a Marco." This embeds the conjugation in real, personal context.

2. Pair dovere with potere and volere. Practice the same sentence with all three modals — "Devo partire / Posso partire / Voglio partire" — to internalize the modal + infinitive pattern and feel the difference in meaning.

3. Listen for dovere in Italian media. In movies, songs, and podcasts, notice when speakers say devo, devi, deve. Hearing these forms in natural speech reinforces your memory far more than drills alone.
