subjunctive

subjunctive (konjunktiv): one of the three moods of the verb phrase, the other two being the indicative and the imperative. The subjunctive is rare in present-day English, though it is sometimes used in counter-factual clauses (if -clauses, concessive clauses, etc.), e.g. If I were rich, I’d just travel all the time (- I'm not rich). With verbs other than be, the indicative is nearly always used in this kind of clauses.
