Modal verbs are a type of auxiliary verb that modify the meaning of the main verb. The modal verbs include can/could, may/might, will/would, shall/should, ought to, and must. Modal verbs are different from normal verbs in that they don't use an 's' for third person singular and they make questions through subject-verb inversion. They are also followed directly by the infinitive form of another verb without using 'to'. The document then provides detailed explanations and examples of how to use each individual modal verb.
