What is the Spanish Subjunctive Mood?
The Spanish subjunctive mood (subjuntivo) expresses subjectivity, uncertainty, emotion, desire, and hypothetical situations. Unlike the indicative mood, which states facts, the subjunctive expresses what might be, what we hope for, or what we doubt.
The subjunctive is one of the most challenging aspects of Spanish grammar but is essential for expressing nuanced thoughts and emotions.
Examples
Espero que tengas un buen día.
I hope you have a good day.
Dudo que María venga a la fiesta.
I doubt María will come to the party.
Es importante que estudies para el examen.
It's important that you study for the exam.
Present Subjunctive Formation
The present subjunctive is formed by taking the yo form of the present indicative, dropping the -o ending, and adding subjunctive endings. This method works for most verbs, including many irregulars.
Regular -AR Verbs
For -AR verbs, take the yo form, drop -o, and add -e endings:
AR Verbs: hablar → hable
| Pronoun | Conjugation | English |
|---|---|---|
| yo | hable | I speak/may speak |
| tú | hables | you speak/may speak |
| él/ella/usted | hable | he/she speaks, you speak |
| nosotros/nosotras | hablemos | we speak/may speak |
| vosotros/vosotras | habléis | you all speak/may speak |
| ellos/ellas/ustedes | hablen | they speak, you all speak |
Quiero que hables más despacio.
I want you to speak more slowly.
Es necesario que estudiemos juntos.
It's necessary that we study together.
Regular -ER/-IR Verbs
For -ER and -IR verbs, take the yo form, drop -o, and add -a endings:
ER/IR Verbs: comer/vivir → coma/viva
| Pronoun | Conjugation | English |
|---|---|---|
| yo | coma/viva | I eat/live |
| tú | comas/vivas | you eat/live |
| él/ella/usted | coma/viva | he/she eats/lives |
| nosotros/nosotras | comamos/vivamos | we eat/live |
| vosotros/vosotras | comáis/viváis | you all eat/live |
| ellos/ellas/ustedes | coman/vivan | they eat/live |
No creo que coma carne.
I don't think he eats meat.
Espero que vivan felices.
I hope they live happily.
Stem-Changing Verbs
Stem-changing verbs follow the same pattern as in the present indicative, but -ir verbs have additional changes in nosotros and vosotros forms:
Stem Changes: pensar → piense, dormir → duerma
| Pronoun | Conjugation | English |
|---|---|---|
| pensar (e→ie) | piense, pienses, piense, pensemos, penséis, piensen | to think |
| dormir (o→ue, o→u) | duerma, duermas, duerma, durmamos, durmáis, duerman | to sleep |
| pedir (e→i) | pida, pidas, pida, pidamos, pidáis, pidan | to ask for |
Dudo que piense en nosotros.
I doubt he thinks about us.
Es raro que durmamos tan poco.
It's strange that we sleep so little.
