Dejé salir a mi hijo vs. permití que mi hijo saliera

Introduction

This article explains the difference between two Spanish ways to express allowing someone to do something: Dejé salir a mi hijo and Permití que mi hijo saliera. You will learn grammar, nuance, and usage with clear examples for beginner to intermediate learners, plus tips on when to choose one form over the other.

Overview: Two ways to say allow

Spanish offers more than one way to say allow or let. One option uses verbs like dejar followed by an infinitive. The other uses verbs like permitir followed by que plus the subjunctive. Each structure has its own grammar rules, meaning differences, and register (formality level).

Key terms

Dejar + infinitive: dejar salir, dejar entrar, dejar trabajar.
Permitir + que + subjunctive: permitir que salga, permitir que entre, permitir que trabaje.

Grammar: dejar + infinitive

When you use dejar followed by an infinitive, the construction is simple and very common in spoken Spanish. The subject of dejar is the person who gives permission, and the infinitive describes the permitted action. No que or subjunctive is required.

Form: Subject + dejar (conjugated) + infinitive + optional object.

Examples:

Yo dejé salir a mi hijo.

Ella deja entrar a los invitados.

Nosotros dejamos usar el coche a mi hermano.

Conjugation and agreement

Only dejar is conjugated. The infinitive stays in the base form regardless of the subject who performs the action. This makes the structure straightforward for learners.

Example with different subjects for the action:

Mi madre dejó cocinar a mi hermana.
Mi madre dejó cocinar a los niños.

Common uses and tone

Dejar + infinitive is colloquial and direct. It is used in everyday conversation, family contexts, and informal writing. It often emphasizes the act of letting rather than the formal permission process.

Grammar: permitir + que + subjunctive

The verb permitir requires a subordinate clause introduced by que when you want to say someone is permitted to do something. Because the subordinate clause refers to a hypothetical, desired, or non-factual action from the speaker’s perspective, Spanish uses the subjunctive mood inside that clause.

Form: Subject + permitir (conjugated) + que + subject of subordinate clause + verb in present/past subjunctive.

Examples:

Yo permití que mi hijo saliera.
Ella permite que los estudiantes usen el teléfono en clase (present subjunctive: usen).

Why the subjunctive?

The subjunctive appears because permission often involves possibility, desire, or non-asserted events. In Spanish grammar, que + subjunctive is the standard way to express these attitudes when the main verb indicates influence, emotion, doubt, or will.

Conjugation notes

Conjugate permitir to match the person granting permission. Use the appropriate tense of the subjunctive for the permitted action: present subjunctive for current/future permission, imperfect subjunctive for past permission.

Examples with tense variation:

Present: Le permito que salga a las ocho.

Past: Le permití que saliera a las ocho.

Direct comparison: Dejé salir a mi hijo vs. Permití que mi hijo saliera

Both sentences communicate that the speaker allowed their child to leave, but there are subtle differences to consider: simplicity, focus, formality, and nuance of meaning.

Simplicity and directness

Dejé salir a mi hijo is shorter and more direct. It focuses on the action of letting the child go out. This makes it more common in casual conversation: parents telling another parent what happened, quick explanations, and spoken narratives.

Permití que mi hijo saliera is longer and more explicit about the permission process. It can sound more formal or legalistic depending on context. Use it when you want to emphasize that you gave permission as a conscious decision.

Focus and emphasis

Dejé salir a mi hijo places emphasis on the action salir — what the child did. The structure presents permission as enabling an action.
Permití que mi hijo saliera puts more emphasis on the permission itself. The subordinate clause frames the leaving as a contingent event that depended on the speaker’s consent.

Register and formality

Use dejar in informal contexts and everyday speech. Use permitir in formal, written, or careful spoken contexts: official statements, school notes, or when discussing rules and policies.

Practical examples and translations

Below are real-world examples with literal and natural-sounding English translations. Note mood and tense choices in Spanish.

Example 1 (past informal):
Dejé salir a mi hijo — I let my son go out.
Permití que mi hijo saliera — I permitted my son to go out.

Example 2 (present permission):
Mi mamá deja usar la computadora — My mom lets me use the computer.
Mi mamá permite que use la computadora — My mom allows me to use the computer.

Example 3 (rules and policies):
Los profesores no dejan hablar durante el examen — Teachers don’t let you talk during the exam.
Los profesores no permiten que los estudiantes hablen durante el examen — Teachers do not permit students to speak during the exam.

Example 4 (past nuance):
Dejé entrar a los invitados a las nueve — I let the guests come in at nine.
Permití que los invitados entraran a las nueve — I allowed the guests to enter at nine.

When one is preferred over the other

Choose dejar when you want to sound natural and informal. It is often the easiest and most efficient choice for spoken language.

Choose permitir when you need clarity, formality, or when you are discussing permissions as policies, rules, or decisions. It fits well in contexts such as school, workplace, legal, or bureaucratic settings.

Subtle meaning differences

Sometimes dejar can imply passive allowance or inattention: the speaker did not prevent an action. For example, Dejé que se fuera could mean I didn’t stop them, maybe out of choice or indifference. Permitir tends to imply an active decision to allow.

Compare:

Dejé que se fuera — I let him/her leave (maybe I stepped aside or chose not to stop them).
Permití que se fuera — I allowed him/her to leave (I made a deliberate decision).

Common collocations and verbs similar to dejar and permitir

Other verbs and expressions convey permission and follow similar patterns. Learning these will help you vary your speech and understand nuances.

Verbs that use infinitive like dejar:

permitir (can also be used with infinitive in casual speech: me permites salir?)
autorizar + infinitive (more formal)
dejar + que + subjunctive is possible for emphasis: Dejé que mi hijo saliera, but this mixes patterns and often sounds more emphatic.

Verbs that require que + subjunctive:

permitir que, prohibir que, aconsejar que, pedir que (for requests), mandar que (for orders).

Pronoun placement and negative forms

Pronouns attach to infinitives, gerunds, and affirmative commands, which affects dejar constructions more often. In negative forms, use no before the verb and the subjunctive when required.

Examples:

No dejé salir a mi hijo — I didn’t let my son go out.
No permití que mi hijo saliera — I didn’t allow my son to go out.

With pronouns:

Lo dejé salir temprano — I let him leave early.
No lo dejé salir temprano — I didn’t let him leave early.

Cultural and usage notes

In many Spanish-speaking countries, family conversations favor dejar because it is natural and warm. Teachers, administrators, and official notices will typically use permitir when specifying rules. Pay attention to tone: choosing one form over the other can make your Spanish sound more casual or more formal.

Also note regional preferences. Some speakers may use permitir interchangeably with dejar in conversation, while others reserve permitir for more formal contexts. Exposure to native speech in your target region will help you sense these patterns.

Quick tips for learners

When in doubt, use dejar + infinitive for spoken Spanish and fast answers. Use permitir + que + subjunctive when writing formally or discussing rules and permissions. Remember subjunctive after que and conjugate only the main verb in the infinitive construction.

Practicing both structures will improve flexibility. Try listening to native dialogues, noticing whether speakers choose one form over the other, and imitate the register and tone you want to achieve.

Conclusion

Dejé salir a mi hijo and Permití que mi hijo saliera both express giving permission, but they differ in formality, focus, and grammar. Use dejar + infinitive for direct, conversational permission and permitir + que + subjunctive for formal or rule-based contexts. Understanding these differences helps you speak and write Spanish more precisely and naturally.
