What does dejar que mean?
Dejar que literally means to let or to allow. Use it when someone permits another person to do something. The structure is: subject + dejar + que + another subject + verb in the subjunctive when the action is not presented as a fact or is influenced by the first subject.
Examples in English: I let her go; She lets him eat. In Spanish: Dejé que saliera; Ella deja que él coma.
Basic sentence structure
The core parts are: the main verb dejar, a subordinating conjunction que, and a subordinate clause with its own subject and verb.
Pattern: Subject A + dejar (conjugated) + que + Subject B + Verb (subjunctive)
Example: Yo dejé que mi hija saliera.
Why use the subjunctive after dejar que?
The subjunctive appears in subordinate clauses when the main clause expresses influence, desire, emotion, doubt, or uncertainty. With dejar que, the main clause expresses permission or influence over someone else’s action, which typically triggers the subjunctive.
Think of the speaker shaping or permitting an action rather than simply stating a neutral fact. That influence is what invites the subjunctive mood.
When to use the subjunctive vs the indicative
Use the subjunctive when the speaker allows, permits, or influences another person’s action, especially when the permission is not described as a completed, factual event.
Examples:
Yo dejo que mi hijo juegue en el parque.
Here the permission is ongoing or general, so the present subjunctive juegue is used.
In contrast, use the indicative when the subordinate clause reports a factual action or when dejar means to leave something behind rather than to permit.
Examples:
Dejé las llaves en la mesa.
Here dejar means to leave (a physical object) and the indicative is natural: dejé (past), las llaves quedaron (indicative).
When the action is presented as a completed fact, some speakers can use the indicative: Dejó que su hijo se fuera. In many cases the past subjunctive se fuera is preferred because permission remains an act of influence.
Conjugation patterns to know
You only need to conjugate dejar in the main clause to match who gives the permission. The verb in the subordinate clause uses the subjunctive and must be conjugated to match the person performing the action.
Present tense examples:
Yo dejo que tú vayas.
Ella deja que su hijo juegue.
Nosotros dejamos que ellos participen.
Preterite and imperfect examples:
Preterite: Dejé que mi hija saliera.
Imperfect: Dejaba que mis amigos vinieran cuando eran niños.
Common subjunctive forms used after dejar que:
Present subjunctive: salga, coma, viva, hable, juegue.
Imperfect subjunctive: saliera/saliese, comiera/comiese, viviera/viviese.
Notes on imperfect subjunctive variants
Spanish has two acceptable imperfect subjunctive endings: -ra and -se. Both are correct; the -ra form is more common in spoken Spanish. Example: saliera or saliese.
Examples with translations and line breaks
Yo dejé que mi hija saliera temprano.
I let my daughter go out early.
Mi madre no deja que yo fume en la casa.
My mother does not let me smoke in the house.
El profesor no dejó que los estudiantes usaran los móviles durante el examen.
The teacher did not allow the students to use phones during the exam.
Los padres dejaron que los niños comieran helado antes de la cena.
The parents allowed the kids to eat ice cream before dinner.
¿Dejas que tu perro suba al sofá?
Do you let your dog get up on the couch?
Negative forms and nuance
To deny permission, put no before dejar. The subjunctive remains in the subordinate clause because the main clause still expresses influence or prohibition.
Example: No dejé que saliera.
I did not let her go out.
Use of negative forms can also add a stronger sense of restriction: No te dejo que manejes tan rápido.
I won’t let you drive that fast.
Imperatives and dejar que
When giving a command that grants permission, use the imperative for dejar and the subjunctive for the subordinate verb.
Examples:
Déjalo que hable.
Let him speak. (formal imperative)
Déjame que lo intente.
Let me try it.
Comparing dejar que with permitir and dejar + infinitive
Permitir is a synonym that also requires the subjunctive after que: Permito que mis hijos vean televisión. Both verbs are common; dejar que often feels more colloquial and frequent in spoken Spanish.
Another alternative is using dejar followed directly by an infinitive when the subject of both verbs is the same. In that case, no que and no subjunctive are needed.
Example with infinitive: Me dejaste salir temprano.
The subject I is the same for both verbs so no que and no subjunctive.
Compare:
Dejé que mi hija saliera.
The subject of dejar (I) is different from the subject of salir (my daughter), so use que + subjunctive.
Quick decision guide
If both actions share the same subject, use dejar + infinitive. If the subject changes, use dejar que + subjunctive (normally).
Time references and aspect
The tense of dejar and the subjunctive in the dependent clause must reflect time and aspect. Use present subjunctive for current or general permissions, and imperfect subjunctive for past permissions or hypothetical past contexts.
Present permission: Yo dejo que salgas a las nueve.
Past permission: Ayer dejé que salieras a las nueve.
Habitual past: Cuando era niño, mis padres dejaban que me quedara hasta tarde.
Conditional and hypothetical situations
In conditional or hypothetical contexts, the imperfect subjunctive can express unreal or counterfactual permissions.
Example: Si hubieras pedido permiso, te habría dejado que fueras.
If you had asked for permission, I would have let you go.
Cultural and pragmatic notes
Spanish speakers often express permission in slightly different ways depending on region and formality. Dejar is widely used in everyday speech across Spain and Latin America. In more formal contexts, permitir or autorizar might sound more official.
Politeness matters: Use por favor or a softener when asking for permission. Example: ¿Me dejas que entre? or ¿Me permites entrar, por favor?
When talking about children, parents commonly use dejar to set limits, so you will hear many everyday examples: Te dejo ver la tele una hora; No te dejo ir solo.
Common mistakes and how to avoid them
1. Forgetting the subjunctive: Remember that a change of subject typically triggers the subjunctive after que. If the subject of dejar and the subordinate verb is different, use the subjunctive.
Incorrect: Dejé que ella sale.
Correct: Dejé que ella saliera.
2. Using que unnecessarily: If the subject is the same, do not use que + subjunctive; use the infinitive instead.
Incorrect: Dejé que salir temprano.
Correct: Dejé salir temprano or Dejé salir a mi hijo temprano (if context makes the subject clear).
3. Confusing dejar meaning to leave: Context matters. Dejar can mean to leave behind or to allow. Translate carefully based on surrounding words.
Example: Dejé mi libro en la mesa means I left my book on the table, not I allowed my book to be on the table.
Advanced tips for intermediate learners
Listen for nuance in native speech: Some speakers use the indicative in colloquial past narratives, especially in Latin America, but the subjunctive remains grammatically safer with permission verbs when the subject changes.
Practice noticing subject changes. When you hear a sentence with dejar, identify whether the action belongs to the same subject or another person. That choice will determine mood and structure.
Expand vocabulary with synonyms: permitir, autorizar, consentir. Compare their registers and typical contexts to sound more natural.
Conclusion
Dejar que plus the subjunctive is the go-to pattern for expressing permission when two different subjects are involved. Use the infinitive when the subject stays the same. Pay attention to tense and nuance: present subjunctive for current permissions, imperfect subjunctive for past or hypothetical ones. With practice, this construction becomes natural and very useful in everyday Spanish.
