It consists of the auxiliary will (or sometimes shall in the first person, as above), the bare infinitive have, and the past participle of the main verb. It indicates an action that is to completed sometime prior to a future time of perspective, or an ongoing action continuing up to a future time of perspective (compare uses of the present perfect above). here are some examples:

MODAL VERBS: A modal verb (also modal, modal auxiliary verb, modal auxiliary) is a type of auxiliary verb that is used to indicate modality that is, likelihood, ability, permission, and obligation. Examples include the English verbs can/could, may/might, must, will/would, and shall/should. A modal auxiliary verb gives much information about the function of the main verb that it governs. Modals have a wide variety of communicative functions, but these functions can generally be related to a scale ranging from possibility ("may") to necessity ("must"), in terms of one of the following types of modality:
MOST COMMON MODAL VERBS ARE: CAN:Can I get your name please? COULD:Could you tell me where the bank is ? MAY:May I Know the reasons why you are leaving? DO:Do you need some help with that? WOULD:Would you like to come with us? SHOULD:Should I need to be here? There many other modal verbs that are important to understand but these are the most important for you to understand English.
