As well in English; there are three moods in Spanish, namely, the indicative, the subjunctive, and the imperative. The subjunctive occurs in some English sentences, too. There are few direct correspondences, however, between the use of the subjunctive in English and in Spanish. In most cases, the subjunctive in Spanish is expressed in English by the indicative or an infinitive.
The subjunctive mood expresses an attitude, and is subservient to, or contingent upon some leading or governing idea expressed in an independent clause of causation, doubt, desire, emotion or uncertainty. The subjunctive is a secondary or dependent thought or idea, and is found in the dependent clause. The subjunctive never makes a direct statement, nor asks a direct question.
The subjunctive mood describes what is beyond the speaker s experience or knowledge, what is unknown.
Present Subjunctive
The present subjunctive is formed by attaching the following endings to the stem of the first person singular of the present indicative of regular and irregular verbs.
