9. Феъли модали ва вахифахои грамматикии он
Modal verbs are used in conjunction with verbs to express their function. Examples are permission, obligation, lack of necessity, possibility, ability, prohibition, advice and probability. You must remember that modal verbs are followed by an infinitive but without the word “to”. Modal verbs are different from other auxiliary verbs as they cannot stand alone in a sentence. They should always be followed by the base verb word (infinitive) like, play, work, run, and eat. Conjugated verbs such as: likes, played, working, ran and eats do not work with modalmodal verbs.
