1. Present Subjunctive Tense Formation of Irregular Verbs

The Present Subjunctive Tense is used to express:

·         Uncertainty. For example, No creo que regresen esta noche. (I don’t think they will return tonight.)

·         Feelings. For example, Se alegra que venga su amiga. (She is happy that her friend is coming.)

·         Desires. For example, Quiero que tengas un buen viaje. (I want you to have a good trip.)

·         Hypothetical Situations. For example, Quizás visite este domingo. (Perhaps he is visiting this Sunday.)

There are some verbs that are irregular and stem-changing in the subjunctive form. Use the same formula for the formation of the subjunctive by using the first person singular of the present indicative form.

For example:

If it is irregular in the first person indicative, it is irregular in the subjunctive.

With the stem-changing verbs in the subjunctive form, the rule indicates that we take the first person of the preterit tense of the verbs with the endings car, gar, and zar and remove the accent mark.

For example:

In order to maintain the sound of the letters g, gu, and c, we have to change the g to j, the gu to g, and the c to z in the subjunctive form.

For example:

• Dar

• Estar

• Haber

• Ir

• Saber

• Ser
