Modal verbs have distinctive meanings, but these meanings need to be completed by the meanings of main verbs. 2. Modal verbs do not stand on their own. They need to be directly or indirectly associated to a verb. 3. The regular structure of modal verbs in a sentence is modal verb + main verb without TO. 4. Modal verbs do not take third person –S in the Simple Present Tense. 5. Modal verbs do not require auxiliary verbs to form the interrogative or negative forms. The interrogative form is expressed through subjectmodal verb inversion and the negative form, through the addition of NOT after the modal verb.
