Modal verbs are the verbs “can”, “want” and “must”. They are the most useful verbs for a beginner, because one modal verb plus an infinitive gives you hundreds of ready sentences: I want to eat, I can help, I must go. You don’t need to conjugate the second verb at all, it stays in the dictionary form.

VOLERE – to want

Io voglio I want
Tu vuoi You want
Lui, Lei vuole He, she wants
Noi vogliamo We want
Voi volete You want
Loro vogliono They want

Voglio mangiare – I want to eat

Vuoi un caffè? – Do you want a coffee?

Vogliamo imparare l’italiano – We want to learn Italian

A polite note: “voglio” sounds very direct, like a child demanding candy. When you order something in a bar or a restaurant, use the conditional form vorrei – I would like: “Vorrei un cappuccino, per favore”. We will study the conditional mood later in the course, but learn “vorrei” right now, you will need it on day one in Italy.

POTERE – can, to be able to

Io posso I can
Tu puoi You can
Lui, Lei può He, she can
Noi possiamo We can
Voi potete You can
Loro possono They can

Posso entrare? – May I come in?

Non posso venire oggi – I can’t come today

Puoi ripetere, per favore? – Can you repeat, please?

DOVERE – must, to have to

Io devo I must
Tu devi You must
Lui, Lei deve He, she must
Noi dobbiamo We must
Voi dovete You must
Loro devono They must

Devo andare – I have to go

Dobbiamo studiare oggi – We have to study today

Non devi parlare così – You must not talk like that

SAPERE – to know, to know how

One more verb behaves like a modal: SAPERE. With an infinitive it means “to know how to do something”:

Io so I know
Tu sai You know
Lui, Lei sa He, she knows
Noi sappiamo We know
Voi sapete You know
Loro sanno They know

So nuotare – I can swim (I know how to swim)

Non so cucinare – I can’t cook

Sai dov’è la stazione? – Do you know where the station is?

What is the difference between POTERE and SAPERE? POTERE is about possibility and permission, SAPERE is about skill. “Non posso nuotare” means something stops me (maybe the pool is closed). “Non so nuotare” means I never learned how.

Examples

Voglio comprare una macchina nuova – I want to buy a new car

Non possiamo uscire, piove – We can’t go out, it’s raining

I bambini devono dormire – The children must sleep

Sapete parlare inglese? – Do you know how to speak English?

Puoi aiutarmi? – Can you help me?

Che cosa vuoi fare stasera? – What do you want to do tonight?

Scusi, può parlare più lentamente? – Excuse me, can you speak more slowly? (formal)

Devo lavorare domani – I have to work tomorrow
