Se Me Olvidó: The Accidental SE
In English, you are the one who forgot, dropped, or lost something. In Spanish, the thing "happens" to you. It is a way to say something occurred by accident, without blaming the person. The structure is very common in daily speech, so it is worth learning early.
Quick answer
- Se + me/te/le/nos/les + verb: Se me olvidó la tarea.
- The verb agrees with the thing: Se me cayeron las llaves.
- The pronoun shows who is affected: Se nos acabó el café.
How the structure works
Start with se, add the pronoun for the person affected (me, te, le, nos, les), then the verb. The verb agrees with the thing that happened, not with the person. The thing usually comes after the verb.
| Affected person | Pronoun | Example |
|---|---|---|
| I | me | Se me olvidó la llave. |
| you | te | Se te cayó el celular. |
| he / she | le | Se le perdió el boleto. |
| we | nos | Se nos acabó la leche. |
| they | les | Se les descompuso el coche. |
Singular or plural: the verb follows the thing
If the thing is singular, use the singular verb. If it is plural, use the plural verb.

- Se me olvidaron las llaves.I forgot my keys.Llaves is plural.
- Se me cayó el vaso.I dropped the glass.Singular.
- Se me cayeron los vasos.I dropped the glasses.Plural.

The verb agrees with llaves.

The pronoun goes after se.

Frequently asked questions
What does se me olvidó mean?
It means "I forgot," with the idea that it happened by accident.
Why does the verb agree with the thing?
Because the thing is the grammatical subject. The person is an indirect object.
Can I always say olvidé instead?
Yes. It is correct, but the se version is more natural for accidents.
Is this only for bad events?
No. Se me ocurrió una idea (I had an idea) is also this pattern.
