Reference excerpt

In grammar, a future tense (abbreviated fut) is a verb form that generally marks the event described by the verb as not having happened yet, but expected to happen in the future. An example of a future tense form is the French achètera, meaning "will buy", derived from the verb acheter ("to buy"). The "future" expressed by the future tense usually means the future relative to the moment of speaking, although in contexts where relative tense is used it may mean the future relative to some other point in time under consideration. English does not have an inflectional future tense, though it has a variety of grammatical and lexical means for expressing future-related meanings. These include modal auxiliaries such as will and shall as well as the futurate present tense. Tenseless languages use context, lexical items, aspect and/or mood to indicate time.

Expressions The nature of the future, necessarily uncertain and at varying distances ahead, means that the speaker may refer to future events with the modality either of probability (what the speaker expects to happen) or intent (what the speaker plans to make happen). Whether future expression is realis or irrealis depends not so much on an objective ontological notion of future reality, but rather on the degree of the speaker's conviction that the event will in fact come about. In many languages there is no grammatical (morphological or syntactic) indication of future tense. Future meaning is supplied by the context, with the use of temporal adverbs such as "later", "next year", etc. Such adverbs (in particular words meaning "tomorrow" and "then") sometimes develop into grammaticalized future tense markers. (A tense used to refer specifically to occurrences taking place on the following day is called a crastinal tense.) In other languages, mostly of European origin, specific markers indicate futurity. These structures constitute a future tense. In many cases, an auxiliary verb is used, as in English, where futurity is often indicated by the modal auxiliary will (or shall). However, some languages combine such an auxiliary with the main verb to produce a simple (one-word, morphological) future tense. This is the origin of the future tense in Western Romance languages such as French and Italian (see below). A given language may have more than one way to express futurity. English, for example, often refers to future events using present tense forms or other structures such as the going-to future, besides the canonical form with will/shall. In addition, the verb forms used for the future tense can also be used to express other types of meaning; English again provides examples of this (see English modal verbs for the various meanings that both will and shall can have besides simply expressing futurity).

Germanic languages In Germanic languages, including English, a common expression of the future is using the present tense, with the futurity expressed using words that imply future action (I go to Berlin tomorrow or I am going to Berlin tomorrow). There is no simple (morphological) future tense as such. However, the future can also be expressed by employing an auxiliary construction that combines certain present tense auxiliary verbs with the simple infinitive (stem) of the main verb. These auxiliary forms vary between the languages. Other, generally more informal, expressions of futurity use an auxiliary with the compound infinitive of the main verb (as with the English is going to ...).

English English grammar provides a number of ways to indicate the future nature of an occurrence. Some argue that English, like most Germanic languages, does not have a future tense—that is, a grammatical form that always indicates futurity—nor does it have a mandatory form for the expression of futurity. However, through gradual development from its Germanic roots, English became what is now considered a strongly future-tense-marking language. Currently, there are several generally accepted ways to indicate futurity in English, and some of them—particularly those that use will or shall as the most universal and widely used—are frequently described as future tense while some may argue these verbs serve both as present modal verbs and future tense markers. 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" or "I shall win". (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," in the sense of "He is wont to make rude remarks," meaning he has a habit of doing so; or, "You shall stop making rude remarks," which is giving an order). For details of these meanings, see the sections on will and shall in the article on English modal verbs. The form of the will/shall future described above is frequently called the simple future (or future simple). Other constructions provide additional auxiliaries that express particular aspects: the future progressive (or future continuous) as in "He will be working"; the future perfect as in "They will have finished"; and the future perfect progressive as in "You will have been practising." For detail on these, see the relevant sections of Uses of English verb forms. (For more on expressions of relative tense, such as the future perfect, see also the section above.) Several other English constructions commonly refer to the future:

Worked examples

Example 1 — a first encounter with Future tense

Start with the simplest possible case. Write down what Future tense claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Future tense before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Future tense ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Future tense

In research: Future tense appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Future tense in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Future tense is common in secondary-school and first-year university syllabi. It links to neighbouring topics Future, Grammatical tenses, so understanding it makes those chapters shorter.
In everyday life: Look for Future tense outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Future tense in simple terms?

In grammar, a future tense (abbreviated fut) is a verb form that generally marks the event described by the verb as not having happened yet, but expected to happen in the future. An example of a future tense form is the French achètera, meaning "will buy", derived from the verb acheter ("to buy").

Why does Future tense matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Future tense?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
