Definition of the Spanish Subjunctive

The Spanish subjunctive mood is a verb form used to express hypothetical, subjective, or uncertain actions or states. It’s not a tense itself, but rather a mood that modifies the verb’s meaning. Unlike the indicative mood, which describes factual events, the subjunctive deals with possibilities, desires, doubts, emotions, and opinions. The subjunctive is typically found in subordinate clauses, introduced by conjunctions like que (that), si (if), para que (so that), and others. Understanding the subjunctive is key to expressing complex ideas and conveying subtle nuances in Spanish.

Consider these examples to illustrate the difference:

• Indicative: Sé que es verdad. (I know that it is true.) – Expresses a factual knowledge.
• Subjunctive: No creo que sea verdad. (I don’t think that it is true.) – Expresses doubt or disbelief.

The subjunctive is essential for expressing a range of non-factual scenarios, including desires, recommendations, commands, uncertainties, and emotions. It allows speakers to convey their personal perspectives and attitudes towards events and situations.

Structural Breakdown of the Subjunctive

The formation of the subjunctive varies depending on the tense. However, the present subjunctive is the most commonly used. The general rule for forming the present subjunctive involves taking the yo form of the present indicative, dropping the -o ending, and adding the following endings:

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

For example:

• 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

Irregular verbs in the present indicative often have irregular forms in the present subjunctive as well. Some common irregular verbs include:

• Ser (to be): Sea, seas, sea, seamos, seáis, sean
• Estar (to be): Esté, estés, esté, estemos, estéis, estén
• Tener (to have): Tenga, tengas, tenga, tengamos, tengáis, tengan
• Hacer (to do/make): Haga, hagas, haga, hagamos, hagáis, hagan
• Ir (to go): Vaya, vayas, vaya, vayamos, vayáis, vayan
• Saber (to know): Sepa, sepas, sepa, sepamos, sepáis, sepan

Understanding these basic rules is crucial for forming and using the subjunctive correctly. Irregular verbs often require memorization, as their subjunctive forms do not follow the standard patterns.

Types and Categories of the Subjunctive

The Spanish subjunctive has several tenses, each with its own specific uses. The most common are the present and imperfect subjunctive. The future subjunctive is rarely used in modern Spanish.

Present Subjunctive

The present subjunctive is used to express doubts, desires, emotions, recommendations, and possibilities in the present or future.

Examples:

• Espero que vengas. (I hope that you come.)
• Dudo que sea cierto. (I doubt that it is true.)
• Quiero que estudies más. (I want you to study more.)

Imperfect Subjunctive

The imperfect subjunctive is used to express past doubts, desires, emotions, and possibilities, or to make polite requests. There are two forms of the imperfect subjunctive, 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 following endings:

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

Examples:

• Si tuviera dinero, viajaría. (If I had money, I would travel.) (Also: Si tuviese dinero, viajaría.)
• Quería que vinieras. (I wanted you to come.) (Also: Quería que vinieses.)
• Ojalá pudiera ayudarte. (I wish I could help you.) (Also: Ojalá pudiese ayudarte.)

Future Subjunctive (Rare)

The future subjunctive (futuro de subjuntivo) is rarely used in modern Spanish. It was used to express future possibilities or conditions in formal or legal contexts. Today, it is mostly found in legal documents or set phrases.

Example:

• Si alguien fuere culpable, será castigado. (If anyone should be found guilty, they will be punished.)

Perfect Subjunctive

The perfect subjunctive (pretérito perfecto de subjuntivo) is used to express actions that have been completed before another action in the past or present. It is formed using the present subjunctive of haber (to have) + the past participle.

Example:

• Me alegra que hayas venido. (I’m glad that you have come.)
• Dudo que hayan terminado el trabajo. (I doubt that they have finished the work.)

Pluperfect Subjunctive

The pluperfect subjunctive (pluscuamperfecto de subjuntivo) is used to express actions that had been completed before another action in the past. It is formed using the imperfect subjunctive of haber (to have) + the past participle.

Example:

• Si hubiera sabido, te habría ayudado. (If I had known, I would have helped you.) (Also: Si hubiese sabido, te habría ayudado.)
• No creía que hubieran llegado tan tarde. (I didn’t believe that they had arrived so late.) (Also: No creía que hubiesen llegado tan tarde.)

Usage Rules for the Subjunctive

The subjunctive is triggered by specific verbs, expressions, and conjunctions. Recognizing these triggers is essential for using the subjunctive correctly.

“WEIRDO” Verbs and Expressions

A helpful mnemonic for remembering when to use the subjunctive is “WEIRDO,” which stands for:

• Wishes/Desires
• Emotions
• Impersonal expressions
• Requests/Recommendations
• Doubt/Denial
• Ojalá (I hope/wish)

Verbs and expressions that fall into these categories typically trigger the subjunctive in the subordinate clause.

Adverbial Clauses

Certain conjunctions used in adverbial clauses always trigger the subjunctive. These include:

• Antes de que (before)
• Para que (so that)
• A fin de que (in order that)
• A menos que (unless)
• Con tal de que (provided that)
• En caso de que (in case)
• Sin que (without)

Other conjunctions may or may not trigger the subjunctive, depending on whether the action is certain or uncertain. These include:

• Cuando (when)
• Después de que (after)
• Hasta que (until)
• En cuanto (as soon as)

If the action is viewed as habitual or certain, use the indicative. If the action is viewed as future or uncertain, use the subjunctive.

Adjectival Clauses

The subjunctive is used in adjectival clauses when the noun being modified is uncertain, indefinite, or hypothetical. If the noun is specific and known, use the indicative.

“Si” Clauses
(Conditional Sentences)

“Si” clauses express conditions and their potential results. The subjunctive is used in the “si” clause when referring to hypothetical or unlikely situations.

• If the “si” clause refers to a hypothetical situation in the present, use the imperfect subjunctive in the “si” clause and the conditional tense in the main clause.
• If the “si” clause refers to a hypothetical situation in the past, use the pluperfect subjunctive in the “si” clause and the conditional perfect tense in the main clause.

Examples:

• Si tuviera dinero, viajaría por el mundo. (If I had money, I would travel the world.)
• Si hubiera estudiado, habría aprobado el examen. (If I had studied, I would have passed the exam.) (Also: Si hubiese estudiado, habría aprobado el examen.)

Common Mistakes with the Subjunctive

One of the most common mistakes is using the indicative instead of the subjunctive after “WEIRDO” verbs and expressions. For example:

Another common mistake is using the infinitive instead of the subjunctive after certain conjunctions. For example:

Additionally, forgetting to change the verb ending to match the subject in the subjunctive clause is a frequent error. For example:

Finally, confusing the uses of “ser” and “estar” in the subjunctive can lead to errors. Remember that “ser” is generally used for permanent or inherent characteristics, while “estar” is used for temporary states or conditions.
