In everyday Spanish, the subjunctive appears mainly after verbs of desire, subjective opinion, emotion, and doubt. It is also triggered by impersonal expressions like it is necessary that and conjunctions like so that, although, or when when they refer to a future or uncertain action. The decision usually depends on a simple question: does the sentence present a confirmed fact or a pending, desired, or discussed idea? If there is no certainty or the action depends on another, the subjunctive usually appears.

After verbs that express desire, will, order, or necessity, the subjunctive is used in the second action. The usual structure is desire verb + that + subject + subjunctive. I want you to study, they prefer that we arrive early, my boss demands that you sign. Ideas such as to hope that, to ask that, to insist that and to need that also come in.

Doubt, possibility, and the negation of a clear statement push toward the subjunctive. It is used after expressions like I doubt that, I don’t think that, it is possible that, perhaps when the idea is not presented as sure. I don’t think I have time places the second action in the realm of uncertainty. By contrast, if certainty is asserted, the indicative normally appears: I think he has time.

When a sentence expresses joy, fear, surprise, sorrow, anger, or relief, the action that provokes that reaction typically goes in the subjunctive. The structure is emotion + that + subjunctive: I’m glad that you have come, I’m worried that they don’t answer, I’m surprised that I know the answer.

The present subjunctive is formed from the first person of the present indicative. First take yo hablo, yo como, yo vivo and remove the -o. Then add the subjunctive endings. This yields the base habl-, com-, viv-. This point serves for almost all regular verbs and also for many partial irregulars. The yo form of the present indicative is the entryway to build the present subjunctive.

Formation from the first person

Idea
To form the present subjunctive, start from the first person of the present indicative.
The ending changes according to the verb conjugation.
In many verbs, the stem remains and the ending changes.

Verbs ending in -ar form the present subjunctive with the endings -e, -es, -e, -emos, -éis, -en. To the base habl- these endings are added: hable, hables, hable, hablemos, habléis, hablen. With trabajar you get trabaje, trabajes, trabaje, trabajemos, trabajéis, trabajen. The pattern holds for all regular -ar verbs, even when the sound changes a bit due to spelling.

Verbs in -er and -ir share the same scheme in the present subjunctive: -a, -as, -a, -amos, -áis, -an. From comer you get coma, comas, coma, comamos, comáis, coman; from vivir, viva, vivas, viva, vivamos, viváis, vivan. Although the infinitives end differently, the present subjunctive regular uses these same endings for both groups.

Tener gives tenga, tengas, tenga, tengamos, tengáis, tengan. Hacer gives haga, hagas, haga, hagamos, hagáis, hagan. Decir gives diga, digas, diga, digamos, digáis, digan.

The choice depends on how the information is presented. The indicative appears when the speaker sees it as real, objective, or confirmed: I know he’s coming, it’s true that he works. The subjunctive appears when the idea is sought, doubtful, valued, or not proven: I want him to come, I don’t think he works, it’s good that he studies. In sentences like I’m looking for a car that uses little fuel, the subjunctive signals that the car is not yet identified. If the person, thing, or action is already presented as known and real, the indicative is usually used.

Choice according to reality or subjectivity

Idea
Use the indicative when the information is presented as real or proven.
Use the subjunctive when the information is presented as desired or doubtful.
Use the indicative when the speaker states a direct certainty.
Use the subjunctive when the speaker expresses a subjective valuation.

In conversation, some regions use the indicative in contexts where others prefer the subjunctive, especially after verbs of perception, opinion, or possibility. In everyday speech you may hear I think he’s coming alongside I think he come in very specific registers, although the more general use in these cases maintains the distinction between certainty and uncertainty. There are also local differences in fixed expressions and in the politeness tone. What’s important is to recognize that the general rule of the subjunctive remains the same—desire, doubt, valuation, and dependence—even though actual usage may shift a bit by region.
