El concepto del subjuntivo

 

Tenses and moods:

In a sentence, the verb is a word or group of words that identifies the action.  A verb is characterized by its tense and its mood.

 

In English, the subjunctive is used only rarely:

 

Indicative

Subjunctive

You are late.

It is important that you be on time.

I am in school. 

I wish I were on vacation.

Paul speaks English.

The teacher insists that he speak Spanish in class.

In Spanish, however, the subjunctive is used frequently.  As in English, it generally occurs in dependent clauses – that is, in clauses that cannot stand alone and are connected to the main or independent clause:

 

Main clause

Dependent clause

Sugiero...

que Ud. sea más puntual.

(I suggest...

that you be more punctual.)

 

The Indicative and the Subjunctive:

Compare the use of the indicative and the subjuntive in the following sentences:

 

Indicative

Subjunctive

Tomás no trabaja.

Es importante que trabaje.

Creo que es perezoso.

Dudo que sea trabajador.

Sé que limpia su coche.

Quiero que limpie su cuarto también.

 

The indicative mood is objective.  It is used to describe facts.  It states what is considered to be certain.  It is the mood of what is.

The subjunctive mood is subjective.  It is used to express feelings, judgments and emotions relating to and action.  It states what is considered to be desirable, possible, doubtful, uncertain, and so on.  It is the mood of what  may or might be.

 

Both the indicative and the subjunctive may occur in a dependent clause introduced by que.  The choice between the indicative and subjunctive depends on what is expressed by the verb in the main clause.

 

Main clause

Dependent clause

Statement of fact or belief

Indicative

Statement of will, necessity or obligation, emotion or feeling, doubt, possibility

Subjunctive
