In grammar, a future tense (abbreviated fut) is a verb form that marks the event described by the verb as not having happened yet, but expected to happen in the future (in an absolute tense system), or to happen subsequent to some other event, whether that is past, present, or future (in a relative tense system). The concept of the future, necessarily uncertain and at varying distances ahead, means that the speaker may express the future in terms of probability or intent ; the modality of intention is usually but not always present when a future construction is used. Whether future expression is realis or irrealis depends not on any objective, ontological notion of future reality, but rather on the speaker's conviction that the predicted event will at some future moment constitute reality. In many languages there is no morphological or syntactic indication of future tense. Future meaning is supplied by the context, with the use of temporal adverbs such as "later", or "next year", etc.
