antes de + Infinitive

Before Doing

Level 1

Use 'antes de + infinitive' to say 'before doing' an action.

How It Works

Use antes de + infinitive to place one action before another: Me cepillo los dientes antes de acostarme (“I brush my teeth before going to bed”). The verb after de is an infinitive, such as hablar, comer or vivir, rather than a finite form like hablo.

Subjects
In everyday sentences, the infinitive often shares the main subject: the same person brushes their teeth and goes to bed. It can also have its own subject, usually after the infinitive: Salimos antes de llegar Juan (“We left before Juan arrived”). A different subject does not automatically rule out the infinitive.

A Finite Clause
You can also use antes de que + subjunctive: Salimos antes de que llegara Juan. Antes que without de is also standard in this temporal construction. The finite clause can clarify who does the action; it is not reserved exclusively for a change of subject.

Keep the Forms Distinct
Siempre desayuno antes de salir de casa is correct. Do not write antes de salgo: use the infinitive after de, or a finite clause introduced by antes (de) que.

Common Mistakes

  • Conjugating the verb after 'antes de'

    Siempre desayuno antes de salgo de casa.
    Siempre desayuno antes de salir de casa.

    Use the infinitive salir after antes de. A finite clause needs antes (de) que and the subjunctive; salgo cannot directly replace salir after de. This distinction is not a rule that every infinitive must share the main subject.
