2. Introduction to Modals
What are Modals?
Modals are a special type of verb that is used to express
ability, possibility, permission, obligation, and advice. They
are auxiliary verbs, meaning they are used in combination
with other verbs to convey additional meaning. Unlike
regular verbs, modals do not have tenses or change their
form to agree with the subject.
