Spanish Past Participle: Formation, Irregular Forms, and Uses

The past participle (participio pasado or participio pasivo) is one of the most useful forms in Spanish. It appears in perfect tenses, passive constructions, and as an adjective. Once you know how to form it, you can unlock a huge portion of Spanish grammar.

Common Irregular Past Participles

A number of very common verbs have irregular past participles that must be memorised:

Infinitive	Past Participle	Meaning
abrir	abierto	opened
cubrir	cubierto	covered
decir	dicho	said
escribir	escrito	written
hacer	hecho	done / made
morir	muerto	died
poner	puesto	put
resolver	resuelto	resolved
romper	roto	broken

Compounds of these verbs follow the same pattern: describir → descrito, proponer → propuesto, devolver → devuelto.

Use 1: Perfect Tenses (with Haber)

The most common use is in perfect tenses, paired with haber as the auxiliary:

• He hablado con ella. — I have spoken with her.
• ¿Has comido? — Have you eaten?
• Hemos vivido aquí diez años. — We have lived here ten years.
• Había escrito la carta. — He had written the letter. (pluperfect)

When used with haber, the past participle is invariable — it never changes to agree with gender or number:

• Ella ha hablado. ✓ (not hablada)
• Ellos han comido. ✓ (not comidos)

---

Use 2: Passive Voice (with Ser)

With ser as the auxiliary, the past participle forms the passive voice. In this construction, the participle does agree with the subject in gender and number:

• La carta fue escrita por Juan. — The letter was written by Juan.
• Las ventanas fueron rotas. — The windows were broken.
• El proyecto ha sido aprobado. — The project has been approved.
• Las reglas son seguidas por todos. — The rules are followed by everyone.

---

Use 3: As an Adjective

The past participle can stand alone as an adjective. In this role, it agrees with the noun it modifies in gender and number:

• una puerta abierta — an open door
• un libro escrito en francés — a book written in French
• las ventanas rotas — the broken windows
• el problema resuelto — the solved problem

This is often used with estar to describe a resulting state:

• La tienda está cerrada. — The shop is closed.
• El ordenador está apagado. — The computer is off.
• La cena está hecha. — Dinner is done.

---

Use 4: Absolute Participial Clauses

The past participle can open a clause to mean “once/having/after”:

• Terminado el trabajo, salimos. — Once the work was finished, we left.
• Dicho eso, se fue. — Having said that, she left.
• Hecha la pregunta, esperé. — Having asked the question, I waited.

Ser + Participle vs Estar + Participle

This is a subtle but important distinction:

Construction	Meaning	Example
ser + participle	passive action (by someone)	La carta fue escrita por Ana.
estar + participle	resulting state	La carta está escrita.

• La puerta fue abierta por el portero. — The door was opened by the doorman. (action)
• La puerta está abierta. — The door is open. (state)
