se + Verb

Passive Se Construction

Level 4

Use se + a 3rd person verb to say something is done, focusing on the action, not the doer. The verb agrees with the item receiving the action.

How It Works

The passive se is a common way to form passive sentences in Spanish, often preferred over the more formal passive voice with 'ser'. It's used when the agent (the person or thing performing the action) is unknown, unimportant, or obvious from context.

Key Rule: Verb Agreement
The most important rule is that the verb agrees in number with the noun that receives the action. This noun acts as the grammatical subject of the sentence.

  • If the subject is singular, the verb is in the third-person singular.
  • If the subject is plural, the verb is in the third-person plural.

Examples:

  • Se habla español en este restaurante. (Spanish is spoken in this restaurant.) -> español is singular, so habla is singular.
  • Se necesitan más voluntarios. (More volunteers are needed.) -> voluntarios is plural, so necesitan is plural.

This construction is extremely common on signs, in advertisements, and in general statements.

Distinction from Impersonal se
It's crucial not to confuse the passive se with the impersonal 'se'.

  • Passive se: Has a grammatical subject that the verb agrees with. It answers the question "What is being acted upon?"
  • Impersonal se: Does not have a grammatical subject. The verb is always in the third-person singular. It refers to an unspecified human agent, like 'one', 'they', or 'you' in a general sense. Example: Se vive bien aquí. (One lives well here.)

People and Personal A
Compare Se buscan profesores (Teachers are wanted), with plural passive agreement, and Se entrevistó a los profesores (The teachers were interviewed), with singular impersonal se and a personal-a object. Do not use the object’s plurality to force a plural verb in the latter construction.

Not Every Se Is Passive
La puerta se abre can describe a door opening without presenting an agent, or a passive event in an appropriate context. Se alone does not imply that the door deliberately acts on itself. Adding a sí misma explicitly suggests a self-directed reading, which differs from an ordinary report that staff open the door.

Word Order and Compound Tenses
The subject need not follow the verb: Estas casas se venden rápidamente. With haber, the participle stays invariant: Se han vendido las casas. The finite auxiliary han agrees with las casas; vendido does not become vendidas.

Examples (6)

  1. Se vende esta casa.

    This house is for sale.

    Word by Word: passive-marker is-sold this house.

    The verb 'vende' is singular because the subject, 'esta casa', is singular.

  2. Se venden coches usados aquí.

    Used cars are sold here.

    Word by Word: passive-marker are-sold cars used here.

    The verb 'venden' is plural to agree with the plural subject, 'coches usados'.

  3. Se construyó el puente el año pasado.

    The bridge was built last year.

    Word by Word: passive-marker was-built the bridge the year past.

    This construction can be used in any tense. Here, 'construyó' is the singular preterite form.

  4. Se publicaron los resultados ayer.

    The results were published yesterday.

    Word by Word: passive-marker were-published the results yesterday.

    The verb 'publicaron' is in the plural preterite form to match the plural subject 'los resultados'.

  5. En este colegio, se enseñan tres idiomas.

    In this school, three languages are taught.

    Word by Word: In this school, passive-marker are-taught three languages.

  6. ¿Dónde se puede comprar pan sin gluten?

    Where can you buy gluten-free bread?

    Word by Word: Where passive-marker can-be-bought bread without gluten?

    Used here with a modal verb 'poder'. The main verb 'comprar' is in the infinitive, and 'puede' is singular to agree with 'pan'.

Common Mistakes

  • Forgetting to make the verb plural when the subject is plural.

    Se vende entradas en la taquilla.
    Se venden entradas en la taquilla.

    For the standard passive construction intended here, entradas is the plural subject, so use venden. Singular se vende with an inanimate plural noun occurs regionally, but it is not the standard passive agreement pattern taught here.

  • Adding a sí misma when the intended meaning is that staff open the door.

    La puerta se abre a sí misma.
    La puerta se abre a las nueve.

    For the intended routine in which staff open the door at nine, La puerta se abre a las nueve fits. A sí misma explicitly adds a self-directed reading. Without it, La puerta se abre can also mean that the door opens, without implying deliberate agency; not every se sentence is passive or reflexive.

Learn This First

To understand the Passive Se construction, you need to be comfortable with the pronoun 'se' and how to conjugate verbs in the third person (singular and plural). Since the verb must agree with the object being acted upon (which becomes the grammatical subject), knowing how to identify and form plural nouns is also necessary.
