Why passive voice matters

The passive voice changes the focus of a Spanish sentence

The passive voice is not only a verb form. It changes the structure of the sentence: the receiver of the action becomes more important than the person or thing doing the action.

Spanish can use the formal passive with ser + past participle, but it often sounds more natural with passive se or with an active sentence. The useful skill is knowing which structure fits the situation.

Formal passive

El libro fue escrito. The action is presented formally.

Passive se

Se venden casas. Common in signs and announcements.

Resulting state

La puerta está cerrada. The result or state matters.

Learning sequence

Step 1

Formal passive

Step 3

Core idea

What is the passive voice in Spanish?

The passive voice presents the receiver of an action as the main focus of the sentence. In an active sentence, the subject performs the action. In a passive sentence, the subject receives the action.

Active sentence Passive sentence Focus English meaning
Cervantes escribió el libro. El libro fue escrito por Cervantes. The book becomes the subject. The book was written by Cervantes.
La empresa publicó el informe. El informe fue publicado por la empresa. The report becomes the subject. The report was published by the company.
El gobierno aprobó la ley. La ley fue aprobada por el gobierno. The law becomes the subject. The law was approved by the government.
Memory line: passive voice changes the focus from “who did it” to “what was done”.

Formal passive

Formal passive: ser + past participle

The formal passive in Spanish uses a form of ser plus a past participle. The past participle agrees in gender and number with the passive subject.

Passive subject Ser form Past participle Complete sentence
El libro fue escrito El libro fue escrito por Cervantes.
La carta fue escrita La carta fue escrita ayer.
Los informes fueron publicados Los informes fueron publicados por la empresa.
Las reglas fueron aprobadas Las reglas fueron aprobadas oficialmente.
Agreement rule: escrito, escrita, escritos, escritas agree with the passive subject.

Agent

The agent with por

When Spanish names the person or thing that performs the action in a passive sentence, it usually introduces that agent with por.

Spanish passive sentence Agent English meaning Comment
El libro fue escrito por Cervantes. por Cervantes The book was written by Cervantes. The author is named.
La ley fue aprobada por el Congreso. por el Congreso The law was approved by Congress. The institution is named.
El informe fue preparado por el equipo. por el equipo The report was prepared by the team. The performing group is named.
La decisión fue tomada por la dirección. por la dirección The decision was made by management. The decision-maker is named.

Tense

Passive voice with ser in different tenses

The tense of the passive sentence is carried by ser. The past participle still agrees with the passive subject.

Tense Spanish example English meaning Ser form
Present El informe es revisado. The report is reviewed. es
Preterite El informe fue revisado ayer. The report was reviewed yesterday. fue
Imperfect El informe era revisado cada mes. The report was reviewed every month. era
Future El informe será revisado mañana. The report will be reviewed tomorrow. será
Conditional El informe sería revisado si hubiera tiempo. The report would be reviewed if there were time. sería
Present perfect El informe ha sido revisado. The report has been reviewed. ha sido

Passive se

Passive se: the common Spanish alternative

Spanish often prefers passive se instead of the formal passive with ser. This structure is especially common in signs, announcements, instructions and general statements.

Passive se sentence English meaning Agreement Use
Se vende una casa. A house is for sale. Singular: vende Announcement or sign.
Se venden casas. Houses are for sale. Plural: venden Plural passive subject.
Se publicaron los resultados. The results were published. Plural: publicaron Focus on result, not agent.
Se aprobó la ley. The law was approved. Singular: aprobó Institutional or news style.
Se construyeron dos puentes. Two bridges were built. Plural: construyeron Completed passive action.
Passive se rule: in passive se, the verb often agrees with the noun that follows: se vende una casa, se venden casas.

Se contrast

Passive se vs impersonal se

Passive se and impersonal se look similar, but they do not work in exactly the same way. Passive se often has a noun that functions like the passive subject. Impersonal se speaks generally without a specific subject.

Type Spanish example English meaning Structure clue
Passive se Se vende una casa. A house is for sale. Singular noun: una casa.
Passive se Se venden casas. Houses are for sale. Plural noun and plural verb.
Impersonal se Se vive bien aquí. People live well here. No passive subject after the verb.
Impersonal se Se trabaja mucho. People work a lot. General action, no specific subject.

Ser or estar

Ser + past participle describes the passive action. Estar + past participle usually describes the state or result after an action.

Ser + participle Estar + participle Difference

The door was closed by the guard.
La puerta está cerrada.
The door is closed.
Action vs resulting state.

Style choice

Spanish often prefers active sentences

English uses passive voice very often, especially in formal writing. Spanish can use the passive, but many Spanish sentences sound more natural in active voice or with se.

English passive idea Possible formal passive More natural Spanish alternative Comment
The results were published. Los resultados fueron publicados. Se publicaron los resultados. Se often sounds natural in news or reports.
Spanish is spoken here. El español es hablado aquí. Se habla español aquí. Se habla is the normal phrase.
The law was approved. La ley fue aprobada. Se aprobó la ley. Common in institutional language.
The company was founded in 1998. La empresa fue fundada en 1998. La empresa se fundó en 1998. Both can work; se fundó is common.
Style rule: do not translate every English passive sentence mechanically into ser + participle.

Agreement

Past participle agreement in passive voice

In passive constructions with ser and estar, the past participle behaves like an adjective. It agrees with the subject in gender and number.

Subject Participle form Spanish example English meaning
El contrato firmado El contrato fue firmado. The contract was signed.
La carta firmada La carta fue firmada. The letter was signed.
Los contratos firmados Los contratos fueron firmados. The contracts were signed.
Las cartas firmadas Las cartas fueron firmadas. The letters were signed.

  • Confusing ser and estar: fue cerrado describes the action; está cerrado describes the state.
  • Forgetting agreement in passive se: se vende una casa, but se venden casas.
