B2 Spanish grammar
Passive Se vs Impersonal Se in Spanish
Passive se and impersonal se both hide the actor, but their grammar differs. Passive se has an affected grammatical subject and agrees with it; impersonal se has no stated subject and keeps the verb singular.
Passive se
se + agreeing transitive verb + patient subject
An inanimate or non-specific patient can become the subject and control agreement.
Impersonal se
se + third-person singular verb (+ object/complement)
There is no expressed grammatical subject; human objects take personal a and do not control agreement.
Passive se or impersonal se?
| Diagnostic | Passive se | Impersonal se |
|---|---|---|
| patient | inanimate/non-specific subject | human object with a, or no object |
| agreement | verb agrees: Se repararon los ordenadores. | verb stays singular: Se entrevistó a los candidatos. |
| intransitive/prepositional verb | not available | Se vive bien. / Se habló de problemas. |
A prepositional complement cannot control verb agreement.
passive se vs impersonal se: Identify an inanimate passive subject
With a transitive verb and an affected thing, passive se is available. That thing functions as the subject and controls singular or plural agreement.

The documents were signed.
Use singular impersonal se with a specific human object
When an unspecified actor affects a specific person or group introduced by personal a, keep the verb singular because the people are objects, not passive subjects.
Se entrevistó a los candidatos.Use transitivity and complements as diagnostics
An intransitive verb or a verb followed by a prepositional complement cannot form passive se from that complement, so the construction stays impersonal singular.
Aquí se vive bien. Se habló de varios problemas.Common mistakes
Se reparó los ordenadores.
Se repararon los ordenadores.
When the plural things are passive subjects, the verb must agree with them.
Se entrevistaron a los candidatos.
Se entrevistó a los candidatos.
Personal a marks the candidates as objects in an impersonal construction, so it does not trigger plural agreement.
Se hablaron de varios problemas.
Se habló de varios problemas.
The prepositional phrase with de is not a passive subject, so the impersonal verb remains singular.
