Modal verbs are a type of auxiliary verb that is used to express a variety of meanings, such as possibility, ability, necessity, and permission. They are used with another verb, called the main verb, to form a phrase.
Common modal verbs:
can
could
may
might
must
ought to
shall
should
will
would
How to use modal verbs:
Modal verbs are always followed by the infinitive of the main verb, without the word "to." For example:
I can swim.
You could help me.
She may come to the party.
He might go to the store.
We must finish our homework.
Modal verbs can also be used to form negative sentences. To do this, simply add the word "not" after the modal verb. For example:
I cannot swim.
You could not help me.
She may not come to the party.
He might not go to the store.
We must not finish our homework.
