The subjunctive is a grammatical mood—a feature of the utterance that indicates the speaker's attitude toward it. Subjunctive forms of verbs are typically used to express various states of unreality such as: wish, emotion, possibility, judgement, opinion, obligation, or action that has not yet occurred; the precise situations in which they are used vary from language to language. The subjunctive is one of the irrealis moods—which refer to what is not necessarily real. It is often contrasted with the indicative, which is a realis mood—used principally to indicate that something is a statement of fact.
