Conjugate Subjunctive

Two primary tenses exist in the Spanish language: the indicative and the subjunctive. Spanish speakers use the indicative to express facts, opinions and observations, and they use the subjunctive to express desires, hopes and possibilities. That is, the indicative expresses what is, while the subjunctive expresses what may be. The subjunctive can be in present or imperfect form. Unlike the past indicative, which also has a preterite form, the past subjunctive only takes the imperfect.
