Future tense

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 aimera, meaning "will love", derived from the verb aimer ("love"). English does not have a future tense formed by verb inflection in this way, although it has a number of ways to express the future, particularly the construction with the auxiliary verb will or shall or is/am/are going to and grammarians differ in whether they describe such constructions as representing a future tense in English.

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. Future tense can be denoted by the glossing abbreviation FUT.

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.)
