Italian modal verbs

The Italian verbs dovere (to have to, must), potere (can, to be able to) and volere (to want) are called modal verbs (verbi modali).

These verbs are irregular, so they don't follow the rule we studied to form the present tense. Let's look how they are conjugated in the present tense.
