Spanish Present Subjunctive
Conjugating Verbs in the Present Subjunctive
To conjugate a verb in the present subjunctive, you must first remember what the present indicative yo form of the verb in question is. This is because the stem of present subjunctive verbs comes from the yo form of the present indicative. For many verbs, this will be the same as the infinitive stem, but for many others, such as verbs with spelling changes, stem-changing verbs, and irregular verbs, it will be different.
Present Subjunctive Stem Formula
The formula for finding the present subjunctive stem of a verb is the following:
present subjunctive stem = yo form of present indicative minus o ending
Here are a few examples of present subjunctive stems.
|Infinitive||Yo Present Indicative Form||Present Subjunctive Stem|
Regular Present Subjunctive Endings
Once you have the stem, you will add the present subjunctive ending that matches your subject. There are only two ending sets for the present subjunctive: one for -ar verbs and one for both -er and -ir verbs.
|Subject||-ar Verb Endings||-er and -ir Verb Endings|
