Passive Voice in Spanish
Learn how the passive voice works in Spanish sentence structure. This guide explains the formal passive with ser + past participle, the more common passive se, the difference between ser and estar, how to use por for the agent, and why Spanish often prefers active or se constructions.
Why learn the passive voice with MundoDele?
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.
MundoDele explains the Spanish passive through real sentence patterns: ser + participle, passive se, estar + participle, and active alternatives that often sound more natural in Spanish.
How to use this page
Use this page to understand passive voice as part of Spanish sentence structure. First learn the formal passive with ser. Then compare it with passive se, which is often more natural in Spanish. Finally, study estar + participle for states and results.
Formal passive
Use ser + past participle when the action and agent matter.
El libro fue escrito por Cervantes.
The book was written by Cervantes.
Passive se
Use se + verb for common passive-like structures.
Se venden casas.
Houses are sold / Houses for sale.
Resulting state
Use estar + participle when the result or state is more important than the action.
La puerta está cerrada.
The door is closed.
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. |
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. |
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. |
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: 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 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 + participle vs estar + participle
Ser + past participle describes the passive action. Estar + past participle usually describes the state or result after an action.
| Ser + participle | Estar + participle | Difference |
|---|---|---|
| La puerta fue cerrada por el guardia. The door was closed by the guard. |
La puerta está cerrada. The door is closed. |
Action vs resulting state. |
| El documento fue firmado ayer. The document was signed yesterday. |

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. |
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. |
