Modal Auxiliary Verbs are a special class of auxiliary verbs. Like other auxiliaries, modals help another verb in the sentence. But this special class of verbs follow a different sentence structure, and have their own set of rules.
How Modal Verbs are Special
1.) Modal verbs are always followed by a normal verb in its most basic form. There is no to between the modal and the verb. The verb that follows does not take the 3rd person s, or change in any way.
2.) To form questions, modal verbs invert. They change places with the subject, the same way that the verb to be does.
