The Spanish past participle leads a double life. On one side, it pairs with haber to form compound tenses (he comido, habíamos visto) and stays frozen at -o, no matter who or what is involved. On the other side, it works exactly like an adjective: it agrees in gender and number with the noun it describes, takes article modifiers, and lives comfortably with estar and ser. Mastering the second role is what makes your Spanish sound built rather than translated.
This page covers the adjectival life of the past participle: how it agrees, when to reach for it (especially with estar), and the small but tricky set of verbs that have separate participles for verbal and adjectival use.
The core rule: agreement in gender and number
When the past participle modifies a noun — directly, as a predicate adjective, or after estar / ser — it agrees with that noun in gender and number, exactly like any other adjective ending in -o:
| Singular | Plural | |
|---|---|---|
| Masculine | cerrado | cerrados |
| Feminine | cerrada | cerradas |
La puerta está cerrada porque hace mucho frío fuera.
The door is closed because it's very cold outside.
Los libros están abiertos sobre la mesa del salón.
The books are open on the living-room table.
Las ventanas estaban rotas cuando llegamos al piso.
The windows were broken when we arrived at the flat.
El coche está aparcado en doble fila.
The car is parked in a double row.
The agreement isn't optional or stylistic — it's grammatical. *Las ventanas estaba roto (mixing genders/numbers) sounds as wrong to a Spanish ear as "the windows is broke" sounds in English.
The single most important contrast: haber vs estar
This is the rule that, once internalised, prevents an entire category of mistakes:
| Construction | Participle behaviour | Example |
|---|---|---|
haber
| Always invariable (-o) | He cerrado la puerta. |
estar
| Agrees in gender/number | La puerta está cerrada. |
ser
| Agrees in gender/number | La puerta fue cerrada por el guardia. |
| Participio + noun (attributive) | Agrees in gender/number | Una ventana rota. |
He escrito tres cartas esta mañana. (haber — invariable)
I have written three letters this morning.
Las cartas están escritas en español. (estar — agreement)
The letters are written in Spanish.
Same verb, same participle stem, two different rules — because the role of the participle has shifted from verbal (part of haber + participio) to adjectival (predicate after estar).
Estar + participio: resultant states
The single most common use of the participle-as-adjective is estar + participio to describe the state that resulted from an action. The action happened; what matters now is the present condition.
Cuidado, el suelo está mojado.
Careful, the floor is wet (has been wetted).
La tienda está abierta hasta las diez.
The shop is open until ten.
Estoy cansada después de un día tan largo.
I'm tired after such a long day.
Los niños están dormidos en el sofá.
The kids are asleep on the sofa.
Notice how natural this is for describing states: closed, open, wet, tired, asleep, broken, lost, written, parked. The participle gives Spanish a productive way to turn almost any verb into a state adjective. English does the same thing — but English mostly uses the bare participle ("the door is closed"), while Spanish marks the gender and number, giving you four possible endings for one underlying form.
Ser + participio: the canonical passive
When the participle pairs with ser (not estar), you get the canonical passive voice: the focus is on the action being done to the subject, often with a por (by) phrase naming the agent.
La novela fue escrita por una autora desconocida.
The novel was written by an unknown author.
Las decisiones serán tomadas por el comité.
The decisions will be made by the committee.
The contrast with estar + participio is sharp and worth memorising:
- Ser
- participio = the action of doing X (passive voice, focus on the event)
- Estar
- participio = the state resulting from X (focus on the current condition)
La puerta fue cerrada a las ocho. (action: someone closed it at eight)
The door was closed at eight (someone closed it).
La puerta está cerrada. (state: it's currently in a closed condition)
The door is closed (right now).

Direct attributive use
The participle can modify a noun directly, just like any adjective. It usually follows the noun (Spanish's default position) but can precede for stylistic emphasis:
Necesito una llave perdida del cajón de mi abuela.
I need a lost key from my grandmother's drawer.
Encontramos un cuaderno olvidado en el banco del parque.
We found a forgotten notebook on the park bench.
Los empleados despedidos han recibido una indemnización.
The dismissed employees have received severance.
This use is everywhere in Spanish — much more frequent than in English. Where English would say "the man who was sitting next to me," Spanish often prefers el hombre sentado a mi lado. The participle as compact adjective is a major stylistic feature.
Double participles: when verbal and adjectival forms diverge
A small set of verbs have two participles. The regular form (in -ado / -ido) is the verbal one, used in compound tenses with haber. The irregular form is locked into adjectival use.
| Infinitive | Verbal participle (with haber) | Adjectival participle |
|---|---|---|
| imprimir | imprimido | impreso |
| freír | freído | frito |
| proveer | proveído | provisto |
| elegir | elegido | electo |
| soltar | soltado | suelto |
He imprimido el contrato hace un momento.
I just printed the contract a moment ago.
Aquí tienes el documento impreso.
Here's the printed document.
Hemos freído las patatas en aceite de oliva.
We fried the chips in olive oil.
Las patatas fritas estaban deliciosas.
The chips were delicious.
The Real Academia accepts both forms with haber — you can say he frito — but in practice peninsular speakers strongly prefer the regular form with the auxiliary and the irregular form as the adjective.
Participles in nominalised constructions
The participle can be nominalised — used as a noun — by adding a definite article. The article tells you whether it's masculine, feminine, singular, or plural:
Los heridos fueron trasladados al hospital de inmediato.
The injured (people) were taken to the hospital immediately.
La condenada por el robo apeló la sentencia.
The woman convicted of the theft appealed the sentence.
Lo dicho, dicho está.
What's said is said. (set phrase)
The neuter article lo nominalises the participle in an abstract sense — lo dicho = "what was said," lo perdido = "what was lost," lo escrito = "what was written."
Common Mistakes
❌ La puerta está cerrado.
Incorrect — the participle must agree (feminine: cerrada).
✅ La puerta está cerrada.
The door is closed.
The reflex from compound tenses is to leave the participle in -o. With estar, you must agree. La puerta is feminine, so cerrada.
❌ Las he comprados ayer.
Incorrect — with haber, the participle stays invariable.
✅ Las he comprado ayer.
I bought them yesterday.
Spanish, unlike French, does not agree the past participle with a preceding object pronoun. After haber, the form is locked at -o regardless of what la, las, lo, or los refers to.
❌ Estoy escribido un correo.
Incorrect — this confuses the progressive with estar + participio.
✅ Estoy escribiendo un correo.
I'm writing an email.
Don't confuse estar + participio (state) with estar + gerundio (action in progress). Estoy escribiendo = I'm in the middle of writing. Está escrito = it's already been written, in its final state.
❌ Está fritas las patatas.
Incorrect — agreement: las patatas (fem. pl.) requires fritas.
✅ Están fritas las patatas.
The chips are fried.
Two agreements at once: están (plural verb) and fritas (plural feminine participle). Beginners often agree the verb but forget the participle, or vice versa.
❌ Los hombres son cansados.
Wrong choice of copula — use estar for states.
✅ Los hombres están cansados.
The men are tired.
For a temporary state (tiredness, being open, being closed, being wet), use estar. Ser cansado would mean "to be tiring" (a permanent characteristic, said of a person or activity that tires others) — a completely different meaning.
Key Takeaways
- The participle as adjective agrees in gender and number with the noun it describes.
- With haber, the participle is always invariable (-o). This is the single rule that prevents the most common beginner errors.
- Estar + participio describes a resultant state; ser + participio is the canonical passive (action focus, often with por).
- A few verbs (imprimir, freír, proveer, elegir, soltar) have two participles — regular for verbal use, irregular for adjectival use.
- The neuter lo
- participle nominalises it in an abstract sense (lo dicho, lo escrito).
