The rule at a glance

hacer / dejar / mandar + infinitive

Pronoun before the causative verb: Lo hice trabajar

  • hacer: make / have

    hacer + infinitive

    Lo hice trabajar

    I made him work

  • dejar: let / allow

    dejar + infinitive

    Lo dejé salir

    I let him go out

  • mandar: order

    mandar + infinitive

    Lo mandé callar

    I ordered him to be quiet

  • Hacer and dejar are opposites: Lo hice salir (I made him leave), Lo dejé salir (I let him leave).

Forms

The three main causative verbs are hacer (make/have), dejar (let/allow) and mandar (order). The causative verb is conjugated; the action stays in the infinitive, as in other verb + infinitive patterns.

VerbPatternMeaning
hacer(pronoun) + hacer + infinitivemake / have someone do something
dejar(pronoun) + dejar + infinitivelet / allow someone to do something
mandar(pronoun) + mandar + infinitiveorder / command someone to do something

Where the pronoun goes

The person who does the action is usually the direct object (lo, la, los, las), and the pronoun goes before the conjugated causative verb: Lo hice trabajar (I made him work). With causative hacer it can't attach to the infinitive (not hice trabajarlo). When the infinitive has its own object, the person is often indirect: Le hice leer la carta.

In affirmative commands the pronoun attaches to the causative verb: Déjalo hablar (Let him speak).

Causing or forcing an action, often against resistance, or something that triggers a reaction.

El jefe nos hizo trabajar tarde – The boss made us work late

La película me hizo llorar – The film made me cry

¿Te hizo esperar mucho? Did he/she make you wait long?

Allowing or permitting an action.

Mis padres me dejaron salir – My parents let me go out

No la dejaron entrar – They didn't let her come in

¿Me dejas usar tu móvil? Will you let me use your phone?

Déjalo hablar – Let him speak

3. Ordering someone to do something: mandar

Giving an order or command.

La profesora nos mandó callar – The teacher ordered us to be quiet

¿Quién te mandó venir? Who ordered you to come?

Common mistakes

Pronoun between the verbs

Not this (incorrect): Hice lo trabajar

But this (correct): Lo hice trabajar – I made him work. The pronoun goes before the conjugated causative verb, not between the verb and the infinitive.

Pronoun on the infinitive

Not this (incorrect): Hice trabajarlo

But this (correct): Lo hice trabajar – I made him work. With causative hacer the pronoun can't attach to the infinitive.

Forgetting a after obligar and ayudar

Not this (incorrect): Me obligaron firmar

But this (correct): Me obligaron a firmar – They forced me to sign. Obligar and ayudar take a before the infinitive: La ayudé a estudiar.

Le or lo (leísmo), mandar meaning 'send', hacer que + subjunctive, reflexive infinitives and more examples

Le or lo? (leísmo)

With an infinitive that has no object, the person is the direct object: lo/la hice estudiar. Many speakers in Spain say le for a man (leísmo). It is accepted, but lo/la is safe everywhere; avoid le for this in Latin America.

Lo hice estudiar – I made him study (correct everywhere)

Le hice estudiar – Accepted in Spain for a male person (leísmo)

Le hice leer la carta – I made him read the letter (the infinitive has its own object)

Mandar: order or send

Mandar means "to order" with an infinitive and "to send" with a noun (like enviar). Context tells you which.

Me mandó callar – He/She ordered me to be quiet

Me mandó un mensaje – He/She sent me a message

Hacer que + subjunctive

Hacer/mandar/dejar que + subjunctive is also correct, but the causative with the infinitive is more natural and common in everyday speech.

Hice que estudiara – I made him study (correct, more complex)

Lo hice estudiar – I made him study (simpler, preferred)

Reflexive infinitives

With reflexive verbs, the reflexive pronoun stays with the infinitive: Lo hice levantarse (I made him get up). Causatives need someone to do the action: if no other person is involved, use a simple verb or a direct command instead.
