MODAL VERBS II: CAN, COULD, BE ABLE TO

CAN, COULD and BE ABLE TO are used to express a range of meanings related to mood and modality in English: ability, permission, possiblity...

CAN, COULD are MODAL VERBS, whereas BE ABLE TO is a pseudo modal structure which concords with the subject of the sentence by means of the verb TO BE. BE ABLE TO is always followed by infinitive.
Let's see how it works and practice!!
