There are a group of verbs in Italian called modal verbs. They are also known as helper verbs, as they help another verb, explaining intention, possibility, need or ability. For example:


Parlo italiano – I speak Italian

Voglio parlare italiano – I want to speak Italian

Devo parlare italiano – I must speak Italian


In all of these examples, the main verb is parlare (to speak), but the modal verbs voglio (I want) and devo (I must) tell us more about the circumstances around the main verb.

Tu puoi – You can

Lui / lei può – He / she can

Most of the time a modal verb is followed by another verb. This verb is always in the infinitive, have a look at these examples below:


Voglio andare in Italia – I want to go to Italy (andare is the infinitive form)

Posso partire questo fine settimana – I can leave this weekend (partire is in the infinitive form)

Devo fare la valigia – I have to pack my suitcase (fare is in the infinitive form)

So parlare italiano – I can speak Italian (parlare is in the infinitive form)


Sometimes you will hear the modal verb used by itself, although the main verb is understood:


Vuoi venire alla festa? – Do you want to come to the party?

Mi dispiace, non posso – I’m sorry, I can’t


Vieni al museo con noi domani? – Are you coming with us to the museum tomorrow?

No, non voglio. Preferisco andare al mare -No, I don’t want to. I prefer to go the beach.


Perché studi così tanto? – Why are you studying so much?

Devo! Le lezioni sono molto difficili – I have to! The lessons are very difficult


To make a negative sentence with a modal, you just put non (not) before the modal. Here are some examples:


Non voglio quel telefonino – I don’t want that mobile phone

Non posso uscire? – Can’t I go out?  

Non devo studiare stasera – I don’t have to study this evening

Non so nuotare– I don’t know how to swim / I can’t swim
