Spanish languageSubjuntivo - Spanish Subjunctive - Conjugations of Irregular Verbs

The subjunctive is usually considered the most difficult Spanish verb form for students, but hopefully this lesson will simplify matters for you. In Part I, we learned how to form the present subjunctive of regular verbs. In Part II, we will learn the present subjunctive of irregular verbs. In Parts III, IV, and V, we'll take an in-depth look at using the Spanish subjunctive.

Note: All irregular verbs except for dar and estar (see below) use regular endings for subjunctive conjugations.

Stem-changing verbs: There are three kinds of stem-changing -IR verbs.

1. E --» IE

  • All singular forms (yo, tú, él) and third person plural (ellos) maintain the stem change
  • Nosotros and vosotros forms change E in stem to I
SENTIR Present Subjunctive
...que yo siento sienta
...que tú sientes sientas
...que él/ella/Ud.    siente sienta
...que nosotros sentimos sintamos
...que vosotros sentís sintáis
...que ellos/Uds. sienten sientan

2. E --» I

  • All forms have an I in the stem, whether or not they have it in the present
PEDIR    Present Subjunctive
...que yo pido pida
...que tú pides pidas
...que él/ella/Ud. pide pida
...que nosotros pedimos pidamos
...que vosotros pedís pidáis
...que ellos/Uds. piden pidan

3. O --» UE

  • All singular forms and third person plural maintain the stem change
  • Nosotros and vosotros forms change the O in the stem to U
DORMIR    Present Subjunctive
...que yo duermo duerma
...que tú duermes duermas
...que él/ella/Ud. duerme duerma
...que nosotros dormimos durmamos
...que vosotros dormís durmáis
...que ellos/Uds. duermen duerman

Note: Stem-changing -AR and ER verbs are regular in the subjunctive and are thus explained on the regular conjugations page.

  

Irregular first person singular: Most verbs, including all G verbs, which have an irregular first person singular conjugation use that conjugation as the subjunctive stem.
