What is the present subjunctive of hacer in Spanish?

The present subjunctive of hacer is: haga, hagas, haga, hagamos, hagáis, hagan. Derived from the yo form hago by dropping -o and adding -a endings. The G stays in every form, even nosotros (hagamos) and vosotros (hagáis).

The subjunctive forms double as commands: haga (usted command, do this!), hagamos (let's do it!), hagan (ustedes command). For tú: affirmative command is the irregular haz, but the negative command uses the subjunctive (no hagas eso).

Hacer appears in many fixed phrases that take the subjunctive after triggers: hacer ejercicio (exercise), hacer la cama (make the bed), hacer caso (pay attention), hacer falta (be necessary), hacer frío / calor (be cold/hot).

How to Form the Subjunctive of Hacer

Derive from the Yo Form Hago

Hacer's subjunctive uses the rule yo form minus -o plus opposite-vowel endings. Hago → hag- → haga, hagas, haga, hagamos, hagáis, hagan. Like tener, the G inserted in the yo form carries through every subjunctive form.

hacer → hago → hag- → haga, hagas, haga, hagamos, hagáis, hagan.

Yo form minus -o, plus -a endings.

Standard rule for verbs with irregular yo forms.

G Consistent Across All Forms

Unlike the present indicative (where hacemos, hacéis drop the g), the subjunctive keeps the G in nosotros (hagamos) and vosotros (hagáis). The G is what makes the form recognizably from the yo stem.

Pres. ind.: hacemos. Pres. subj.: hagamos.

Subjunctive: G in all six forms.

Subjunctive = G everywhere. Indicative = G only in yo.

Use for Affirmative Commands too

The subjunctive forms haga / hagamos / hagan / hagáis double as formal commands. Haga is the usted command (do this!); hagan is the ustedes command. The tú affirmative command is different (haz), but the negative tú command uses the subjunctive (no hagas).

Haga la cama. (You, formal: make the bed.) No hagas eso. (Don't do that, informal.)

Formal commands = subjunctive. Negative informal commands = subjunctive.

Subjunctive forms = formal commands + negative informal commands.

Same Triggers as All Subjunctives

Subjunctive of hacer responds to the W.E.I.R.D.O. triggers like any verb: Wishes, Emotions, Impersonal expressions, Recommendations, Doubt, Ojalá. The trigger in the main clause + que forces the subjunctive in the dependent clause.

Quiero que. Es importante que. Dudo que. Recomiendo que.

Same triggers across all verbs.

Trigger + que = subjunctive in the dependent clause.

Common Mistakes with Subjunctive of Hacer

Incorrect: Quiero que haces la tarea. — I want you to do the homework. (wrong, indicative after querer que)

Correct: Quiero que hagas la tarea. — I want you to do the homework.

After querer que, the dependent verb must be in the subjunctive. Haces is the indicative; hagas is the tú subjunctive. The wish trigger forces the mood shift.

Incorrect: Es importante que hacemos ejercicio. — It's important we exercise. (wrong, indicative nosotros after es importante que)

Correct: Es importante que hagamos ejercicio. — It's important we exercise.

After es importante que (an impersonal trigger), the dependent verb must be in the subjunctive. Hacemos is the indicative; hagamos is the nosotros subjunctive with the G consistent across all forms.

Incorrect: Sé que haga su mejor esfuerzo. — I know he's doing his best. (wrong, fact assertion takes indicative)

Correct: Sé que hace su mejor esfuerzo. — I know he's doing his best.

Saber que asserts a fact and takes the indicative (hace), not the subjunctive (haga). Only triggers expressing doubt, wish, or opinion force the subjunctive.
