Here is a list of Modal Verbs in English
- Ought to
Their rules differ from other verbs in a few key ways:
- Never add an “s” when converting them to third person singular.
- Always follow them with an infinitive verb without the “to.”
- Always reverse the order when asking a question – for example, instead of saying, “You can swim,” you would ask “Can you swim?”
Below are some of the situations in which you would use modal verbs.

We use modals such as “may,” “can,” or “could” when asking for, giving, or denying permission to do something.
