1. Modal verbs are auxiliary verbs that can not function as a main verb, as opposed to the auxiliary verbs "be", "do" and "have" that can function as a main verb. Modal verbs express modality, ability, possibility, necessity or other condition. We use them for the future and the conditional. As complementary verbs that are, modal verbs do not work without another verb. This other verb always goes after the modal verb and is in the base form (the infinitive without "to"). Modal verbs are not conjugated and do not have time.
2. DIFFERENCES
2.1. The modal verbs, however, are auxiliary verbps that indicate "modality", that is, they add a specific meaning to the main verb. They are not real verbs, they are special because they do not conjugate nor do they need other auxiliaries to form the negative or interrogative. The modal verbs are: can, could, may, might, must, will, ought to, shall, should, would. Here are some examples: -She may come to the party. She may not come to the party. No "She mays come to the party. Modal verbs do not conjugate, therefore they do not carry third-person singular. -Can she play football? Can she play soccer? In "Does she play football?" Modal verbs do not carry other auxiliaries to do the interrogative. "I should not eat so many sweets. He should not eat so many sweets. "He does not have to eat so many sweets," they do not have other helpers to do the refusal, they just add "not."
