Modal verbs are used to express special meanings such as ability, obligation, possibility, permission, and necessity. They include words like can, could, may, might, will, would, shall, should, and ought to. These verbs are followed by an infinitive without 'to' and do not take the third person singular '-s' except for 'have to' and 'need'. They are used to add a special meaning to a sentence, and their use is essential in English grammar.
