Modal Verbs

Modal verbs come before and modify the main verb in a sentence and help explain ideas like possibility, necessity, or obligation. Here are several modal verbs and their functions:

Might: Expresses uncertainty about the present or future, as in, "I might quit my job next month," or, "It might be cold out, so bring a jacket."

Can: Expresses ability or possibility, as in, "I can speak French and Spanish," or, "Students can get cheaper tickets at the movies." Also asks permission or makes a request, as in, "Can you come over tonight?"

Should: Expresses obligation, as in, "I should study for my math test," or probability, as in, "The package should arrive tomorrow, since I sent it last week." Also gives advice, as in, "I think you should go out with Jesse."

Must: Expresses necessity or obligation, as in, "I must go see my grandmother this weekend." Also gives strong advice, as in, "You must quit smoking now that you're pregnant."
