The "will/shall" future consists of the modal verb "will" or "shall" together with the bare infinitive of the main verb, as in "He will win easily" or "I shall do it when time permits". (Prescriptive grammarians prefer "will" in the second and third persons and "shall" in the first person, reversing the forms to express obligation or determination, but in practice "shall" and "will" are generally used interchangeably, with "will" being more common. For details see "shall" and "will".) The meaning of this construction is close to that expressed by the future tense in other languages. However the same construction with "will" or "shall" can have other meanings that do not indicate futurity, or else indicate some modality in addition to futurity (as in "He will make rude remarks", meaning he has a habit of doing so, or, "You shall act on my behalf", giving an order). For details of these meanings, see the sections on "will" and "shall" in the article on English modal verbs.
