Definition of the Spanish Subjunctive

The subjunctive mood (el subjuntivo) in Spanish is a verb mood that expresses subjective, hypothetical, or emotional states rather than objective facts. It is used in dependent clauses, typically introduced by conjunctions like que (that), si (if), para que (so that), and a menos que (unless). Unlike the indicative mood, which describes what is, the subjunctive describes what someone wants, doubts, fears, or hopes for.

The subjunctive is not a tense but a mood. It exists in different tenses, such as the present subjunctive, imperfect subjunctive, perfect subjunctive, and pluperfect subjunctive.

Each tense is used in specific contexts to convey different shades of meaning.

The main function of the subjunctive is to express subjectivity. This includes a wide range of situations, such as expressing desires, doubts, emotions, opinions, and possibilities.

It is also used in certain types of clauses, such as those expressing purpose, condition, or concession. The use of the subjunctive often depends on the verb or expression in the main clause of the sentence.

Certain verbs and expressions, known as “trigger verbs,” require the use of the subjunctive in the subordinate clause.

Structural Breakdown of the Subjunctive

The subjunctive mood typically appears in subordinate clauses, which are clauses that depend on a main clause for their meaning. The most common structure involves a “trigger” in the main clause that necessitates the use of the subjunctive in the subordinate clause.

This structure is often referred to as the “WEIRDO” structure, an acronym that helps remember the main categories of triggers: Wishes, Emotions, Impersonal expressions, Recommendations, Doubt, and Ojalá.

The basic structure is as follows:

Main Clause (Trigger) + que + Subordinate Clause (Subjunctive)

For example:

Quiero que vengas. (I want you to come.)

In this sentence, quiero (I want) is the trigger in the main clause, and vengas (you come) is the subjunctive verb in the subordinate clause.

The conjunction que is essential in connecting the main and subordinate clauses. However, other conjunctions can also introduce subjunctive clauses, depending on the specific meaning being conveyed. These include para que (so that), a fin de que (in order that), a menos que (unless), en caso de que (in case that), antes de que (before), sin que (without), and con tal de que (provided that).

Formation of the Subjunctive

The formation of the subjunctive mood varies depending on the tense. Here’s a breakdown of the most common subjunctive tenses:

Present Subjunctive

The present subjunctive is formed by taking the yo form of the present indicative, dropping the -o ending, and adding the subjunctive endings. For -ar verbs, the endings are -e, -es, -e, -emos, -éis, -en.

For -er and -ir verbs, the endings are -a, -as, -a, -amos, -áis, -an.

Regular Verb Endings:

-ar verbs: -e, -es, -e, -emos, -éis, -en
-er and -ir verbs: -a, -as, -a, -amos, -áis, -an

Examples:

Hablar (to speak): hable, hables, hable, hablemos, habléis, hablen
Comer (to eat): coma, comas, coma, comamos, comáis, coman
Vivir (to live): viva, vivas, viva, vivamos, viváis, vivan

Stem-changing verbs and irregular verbs follow similar patterns but have some variations. For example, verbs like pensar (to think) and volver (to return) have stem changes in the present subjunctive.

Imperfect Subjunctive

The imperfect subjunctive has two forms, both of which are equally correct and interchangeable. To form the imperfect subjunctive, take the third-person plural (ellos/ellas/ustedes) form of the preterite tense, drop the -ron ending, and add the imperfect subjunctive endings.

The two sets of endings are -ra, -ras, -ra, -ramos, -rais, -ran and -se, -ses, -se, -semos, -seis, -sen.

Regular Verb Endings:

-ra form: -ra, -ras, -ra, -ramos, -rais, -ran
-se form: -se, -ses, -se, -semos, -seis, -sen

Examples:

Hablar (to speak): hablara/hablase, hablaras/hablases, hablara/hablase, habláramos/hablásemos, hablarais/hablaseis, hablaran/hablasen
Comer (to eat): comiera/comiese, comieras/comieses, comiera/comiese, comiéramos/comiésemos, comierais/comieseis, comieran/comiesen
Vivir (to live): viviera/viviese, vivieras/vivieses, viviera/viviese, viviéramos/viviésemos, vivierais/vivieseis, vivieran/viviesen

Future Subjunctive (Rare)

The future subjunctive (el futuro de subjuntivo) is rarely used in modern Spanish. You’ll mostly encounter it in legal or formal documents. It is formed by taking the stem of the infinitive and adding the following endings: -are, -ares, -are, -áremos, -areis, -aren.

Regular Verb Endings: -are, -ares, -are, -áremos, -areis, -aren

Examples:

Hablar (to speak): hablare, hablares, hablare, habláremos, hablareis, hablaren
Comer (to eat): comiere, comieres, comiere, comiéremos, comiereis, comieren
Vivir (to live): vivire, vivieres, vivire, viviéremos, vivireis, vivieren

Perfect Subjunctive

The perfect subjunctive (el pretérito perfecto de subjuntivo) is a compound tense formed with the auxiliary verb haber in the present subjunctive + the past participle of the main verb.

Formula: Haber (present subjunctive) + Past Participle

Examples:

Haber (present subjunctive): haya, hayas, haya, hayamos, hayáis, hayan
Hablar (to speak): haya hablado, hayas hablado, haya hablado, hayamos hablado, hayáis hablado, hayan hablado
Comer (to eat): haya comido, hayas comido, haya comido, hayamos comido, hayáis comido, hayan comido

Pluperfect Subjunctive

The pluperfect subjunctive (el pluscuamperfecto de subjuntivo) is a compound tense formed with the auxiliary verb haber in the imperfect subjunctive + the past participle of the main verb. Like the imperfect subjunctive, it also has two forms. Both are equally valid.

Formula: Haber (imperfect subjunctive) + Past Participle

Examples:

Haber (imperfect subjunctive): hubiera/hubiese, hubieras/hubieses, hubiera/hubiese, hubiéramos/hubiésemos, hubierais/hubieseis, hubieran/hubiesen
Hablar (to speak): hubiera hablado/hubiese hablado, hubieras hablado/hubieses hablado, hubiera hablado/hubiese hablado, hubiéramos hablado/hubiésemos hablado, hubierais hablado/hubieseis hablado, hubieran hablado/hubiesen hablado
Comer (to eat): hubiera comido/hubiese comido, hubieras comido/hubieses comido, hubiera comido/hubiese comido, hubiéramos comido/hubiésemos comido, hubierais comido/hubieseis comido, hubieran comido/hubiesen comido

Uses of the Spanish Subjunctive

The subjunctive mood is used in various contexts to express subjectivity, doubt, emotion, and other non-factual states.

Wishes and Desires

The subjunctive is used to express wishes and desires, often with verbs like querer (to want), desear (to desire), and esperar (to hope). The word ojalá (hopefully) always triggers the subjunctive.

Examples:

Deseo que tengas un buen día. (I wish you have a good day.)
Espero que te guste mi regalo. (I hope you like my gift.)

Doubt and Uncertainty

The subjunctive is used to express doubt and uncertainty, often with verbs like dudar (to doubt), no creer (to not believe), no estar seguro (to not be sure), and expressions like es posible que (it’s possible that) and es probable que (it’s probable that).

Examples:

Dudo que sea verdad. (I doubt that it’s true.)
No creo que venga. (I don’t believe he’s coming.)
No estoy seguro de que lo sepa. (I’m not sure that he knows it.)

Usage Rules of the Spanish Subjunctive

Understanding the specific rules that govern subjunctive usage is crucial for mastering this mood. Here are some key rules to keep in mind:

Subjunctive in Subordinate Clauses: The subjunctive is generally used in subordinate clauses that are dependent on a main clause containing a “trigger” verb or expression.
Trigger Verbs: Certain verbs and expressions consistently trigger the subjunctive in the subordinate clause. These include verbs of desire (querer, desear), emotion (alegrarse, temer), doubt (dudar, no creer), influence (recomendar, sugerir), and impersonal expressions (es importante, es necesario).
Que Connection: The subjunctive clause is often connected to the main clause by the conjunction que. However, other conjunctions such as para que, a menos que, and antes de que can also introduce subjunctive clauses.
Sequence of Tenses: The tense of the subjunctive verb in the subordinate clause often depends on the tense of the verb in the main clause. For example, if the main clause is in the present tense, the subordinate clause will typically use the present subjunctive. If the main clause is in the past tense, the subordinate clause will typically use the imperfect subjunctive.
Subjunctive with Ojalá: The expression ojalá (hopefully) always triggers the subjunctive. For example, Ojalá que llueva mañana (Hopefully, it rains tomorrow).
Subjunctive in Adverbial Clauses: Certain adverbial conjunctions, such as para que (so that), a menos que (unless), and antes de que (before), require the subjunctive in the clause they introduce.
Subjunctive in Relative Clauses: The subjunctive is used in relative clauses when the antecedent is indefinite, hypothetical, or non-existent.

Common Mistakes with the Subjunctive

The subjunctive mood can be challenging for Spanish learners, and certain mistakes are common. Here are some of the most frequent errors and how to avoid them:

Using the Indicative Instead of the Subjunctive: One of the most common mistakes is using the indicative mood when the subjunctive is required. This often occurs when learners fail to recognize the trigger verbs or expressions in the main clause.

Incorrect: Espero que vas a la fiesta.

Correct: Espero que vayas a la fiesta. (I hope that you go to the party.)

Incorrect Conjugation: Another common mistake is conjugating the subjunctive verbs incorrectly. This can be due to a lack of familiarity with the subjunctive verb endings or irregular verb forms.

Incorrect: Quiero que haces la tarea.

Correct: Quiero que hagas la tarea. (I want you to do the homework.)

Forgetting the Que: Omitting the conjunction que between the main and subordinate clauses is a frequent error. The que is essential for connecting the two clauses and signaling the subjunctive.

Incorrect: Dudo sea verdad.

Correct: Dudo que sea verdad. (I doubt that it’s true.)

Misusing Tenses: Incorrectly using the subjunctive tenses, such as using the present subjunctive when the imperfect subjunctive is required, is another common mistake. This often stems from a misunderstanding of the sequence of tenses.

Incorrect: Quería que vayas a la fiesta.

Correct: Quería que fueras a la fiesta. (I wanted you to go to the party.)

Using Subjunctive After Verbs of Certainty: Verbs of certainty such as creer (to believe), pensar (to think), estar seguro (to be sure) are used with indicative unless they are negated.

Incorrect: Creo que venga.

Correct: Creo que viene. (I believe that he is coming.)

Practice Exercises

Advanced Topics

For advanced learners, exploring more nuanced aspects of the subjunctive can further refine their understanding and usage:

Subjunctive vs. Indicative in Adverbial Clauses: The choice between the subjunctive and indicative in adverbial clauses often depends on the speaker’s perspective and the certainty of the event. If the event is viewed as hypothetical or uncertain, the subjunctive is used. If the event is viewed as factual or certain, the indicative is used.
Subjunctive in Conditional Sentences: The subjunctive is used in the “si” (if) clauses of conditional sentences to express hypothetical or contrary-to-fact conditions.
Subjunctive with Variable Conjunctions: Some conjunctions, such as aunque (although), can trigger either the subjunctive or the indicative, depending on the context and the speaker’s perspective.
Subjunctive in Literary Contexts: In literary and formal contexts, the subjunctive may be used more frequently and in more nuanced ways to convey subtle shades of meaning and emotion.

Frequently Asked Questions

Conclusion

The Spanish subjunctive mood is a complex but essential aspect of the language. Mastering the subjunctive allows you to express a wide range of subjective meanings, emotions, and nuances that are not possible with the indicative mood alone.

By understanding the structure, formation, and uses of the subjunctive, and by practicing regularly, you can confidently navigate the complexities of this mood and achieve a higher level of fluency in Spanish. Remember to pay close attention to the trigger verbs and expressions, the sequence of tenses, and the specific contexts in which the subjunctive is required.

With dedication and practice, you can master the Spanish subjunctive and elevate your language skills to new heights.
