The subjunctive mood is used to express subjective information, such as emotions, desires, doubts, and hypothetical situations. It contrasts with the indicative mood, which is used to convey objective facts and statements. Understanding the difference between these two moods is crucial to mastering the Spanish language.

Indicative vs. Subjunctive

The indicative mood is used to express certainty, facts, and objective information. For example:

• María estudia español (María studies Spanish)
• Nosotros vamos al cine (We go to the movies)

The subjunctive mood, on the other hand, is used to express subjective information, such as emotions, desires, doubts, and hypothetical situations:

• Espero que María estudie español (I hope María studies Spanish)
• Quisiera que fuéramos al cine (I wish we would go to the movies)

When to Use the Subjunctive

There are several instances in which the subjunctive mood is required. Here are the most common situations:

Expressing Wishes and Desires

When expressing wishes, desires, or preferences, the subjunctive is used after verbs like querer (to want), preferir (to prefer), and desear (to desire):

• Quiero que tú aprendas inglés (I want you to learn English)
• Ella prefiere que nosotros no vayamos (She prefers that we don’t go)

Giving Advice or Making Recommendations

The subjunctive is used when giving advice or making recommendations using verbs like sugerir (to suggest), recomendar (to recommend), and aconsejar (to advise):

• Te sugiero que estudies más (I suggest that you study more)
• Nos recomiendan que visitemos la playa (They recommend that we visit the beach)

Expressing Doubt, Uncertainty, or Disbelief

When expressing doubt, uncertainty, or disbelief, use the subjunctive after verbs like dudar (to doubt) and no creer (not to believe):

• Dudo que ellos vengan a la fiesta (I doubt they will come to the party)
• No creo que llueva mañana (I don’t believe it will rain tomorrow)

Expressing Emotions and Feelings

The subjunctive is used to express emotions and feelings, such as happiness, sadness, fear, or surprise, following verbs like alegrarse (to be happy), sentir (to feel), and temer (to fear):

• Me alegra que hayas pasado el examen (I’m glad you passed the exam)
• Temo que no haya suficiente comida (I fear there won’t be enough food)

Hypothetical Situations and Conjunctions

The subjunctive is used in hypothetical situations, typically with conjunctions like si (if), como si (as if), a menos que (unless), and en caso de que (in case):

• Si tuviera dinero, viajaría por el mundo (If I had money, I would travel the world)
• Actúa como si supiera todo (He acts as if he knew everything)

Conjugating Verbs in the Subjunctive

Conjugating verbs in the subjunctive mood follows specific rules that vary depending on the verb tense – present, imperfect, or past subjunctive.

Present Subjunctive

To form the present subjunctive, start with the present indicative yo-form, drop the “-o” ending, and add the appropriate subjunctive endings:

-AR verbs: -e, -es, -e, -emos, -éis, -en
-ER/-IR verbs: -a, -as, -a, -amos, -áis, -an

Examples:

• hablar: hable, hables, hable, hablemos, habléis, hablen
• comer: coma, comas, coma, comamos, comáis, coman
• vivir: viva, vivas, viva, vivamos, viváis, vivan

Imperfect Subjunctive

The imperfect subjunctive has two possible sets of endings, both of which are accepted and used interchangeably:

• Set 1: -ra, -ras, -ra, -ramos, -rais, -ran
• Set 2: -se, -ses, -se, -semos, -seis, -sen

To form the imperfect subjunctive, use the third person plural form of the preterite indicative, drop the “-ron” ending, and add the appropriate endings:

Examples:

• hablar: hablara/hablase, hablaras/hablases, hablara/hablase, habláramos/hablásemos, hablarais/hablaseis, hablaran/hablasen
• comer: comiera/comiese, comieras/comieses, comiera/comiese, comiéramos/comiésemos, comierais/comieseis, comieran/comiesen
• vivir: viviera/viviese, vivieras/vivieses, viviera/viviese, viviéramos/viviésemos, vivierais/vivieseis, vivieran/viviesen

Past Subjunctive

The past subjunctive is formed by combining the imperfect subjunctive with the auxiliary verb haber:

• hubiera/hubiese + past participle
• hubieras/hubieses + past participle
• hubiera/hubiese + past participle
• hubiéramos/hubiésemos + past participle
• hubierais/hubieseis + past participle
• hubieran/hubiesen + past participle
