Answer:
Modal verbs are helping/auxiliary verbs that give additional information about the function of the main verb that follows. They express attitudes such as ability, possibility, permission, and suggestion.
Explanation:
Modal verbs help when speaking about ability, making requests and offers, asking permission, and more. The modal verbs in English differ from other verbs, because they are not used separately, and do not indicate a specific action or state, they just reflect its modality, the attitude of the speaker to the action.
