MODAL VERBS

Modal verbs are auxiliary verbs.

They do not expression action, they have no conjugation and they depend on a main verb that is always in infinitive form. No preposition is necessary between verbs. The eight classic modal verbs are: can, could, may, might, should, would, will, and must.

The structure to use modal verbs is:


Affirmative:
(Subject) + Modal + (main verb infinitive) + (object)
I can speak English
I must study every day
I should practice more


Negative:
(Subject) + Modal + not + (main verb infinitive) + (object)
I shouldn't worry so much
I won't forget this
I wouldn't go if I were you


Question:
Modal + (subject) + (main verb infinitive) + object
Can't you see?
Must I go?
Could you pass the salt, please?


Each modal verb is used in a different context and can express different messages:


Can

Could
'Could' is used to request or to express past ability, usually implicit that the action can't be performed today.

May
'May' is used to either ask for permission in a more formal/polite way or to express a considerable possibility.
