Spanish Past Participles: From Regular to Irregular Forms

Key takeaways

• Regular Spanish past participles follow two patterns: -ar verbs – -ado (hablar – hablado); -er and -ir verbs – -ido (comer – comido, vivir – vivido).
• Twelve core verbs have irregular past participles that must be memorised: abrir/abierto, decir/dicho, escribir/escrito, hacer/hecho, morir/muerto, poner/puesto, resolver/resuelto, romper/roto, ver/visto, volver/vuelto, cubrir/cubierto, freír/frito.
• When used with haber in perfect tenses, the past participle is invariable: it does not agree with gender or number: hemos comido, han salido.
• When used as an adjective (without haber), the past participle agrees in gender and number: la puerta abierta (the open door), los libros escritos (the written books).

The Spanish past participle appears in more grammatical environments than most learners initially realize: in compound tenses with haber, in passive constructions with ser, in resulting-state descriptions with estar, and as a standalone adjective. Getting the regular forms right is straightforward; it is the twelve irregular forms, and their compounds, that require deliberate memorization because they include the most common verbs in the language.

This guide covers regular past participle formation, all major irregulars with their compounds, and the four main contexts in which past participles appear in Spanish.

The irregular forms cause persistent errors because they attach to the most-used verbs: hecho (done/made), dicho (said), visto (seen). Errors on these go uncorrected without live feedback.

italki has matched 10M+ learners with teachers since 2007, giving learners access to Spanish teachers who catch he hacido or he volvido in real time and correct the irregular form before it becomes fixed.

Find a Spanish tutor and run compound-tense conversation practice, recent events, things you have or have not done, where past participles appear constantly.

Regular past participle formation

Verb type	Infinitive ending	Past participle ending	Example
-ar verbs	-ar	-ado	hablar – hablado
-er verbs	-er	-ido	comer – comido
-ir verbs	-ir	-ido	vivir – vivido

Examples:

Infinitive	Meaning	Past participle
hablar	to speak	hablado
caminar	to walk	caminado
comprar	to buy	comprado
comer	to eat	comido
beber	to drink	bebido
vender	to sell	vendido
vivir	to live	vivido
recibir	to receive	recibido
salir	to leave	salido

The pattern is entirely regular. Every regular -ar, -er, and -ir verb follows it without exception.

The twelve irregular past participles

These must be memorized. They are also among the most commonly used verbs in Spanish, which means they appear in conversation constantly.

Infinitive	Meaning	Past participle
abrir	to open	abierto
cubrir	to cover	cubierto
decir	to say	dicho
escribir	to write	escrito
freír	to fry	frito
hacer	to do / to make	hecho
morir	to die	muerto
poner	to put	puesto
resolver	to resolve	resuelto
romper	to break	roto
ver	to see	visto
volver	to return	vuelto

A private Spanish tutor can run drills where you hear the infinitive and must produce the irregular participle under time pressure, the speed requirement is what reveals which forms are automatic and which still require conscious recall. italki has 30,000+ teachers across 150+ languages, including qualified Spanish teachers who target exactly these high-frequency irregulars.

Compound verbs with irregular roots

Compound verbs built on irregular roots inherit the same irregular past participle:

Compound	Root	Past participle
componer (to compose)	poner	compuesto
deshacer (to undo)	hacer	deshecho
describir (to describe)	escribir	descrito
descubrir (to discover)	cubrir	descubierto
devolver (to return something)	volver	devuelto
envolver (to wrap)	volver	envuelto
imponer (to impose)	poner	impuesto
proponer (to propose)	poner	propuesto
suponer (to suppose)	poner	supuesto
revolver (to stir / to revolve)	volver	revuelto
reponer (to restock / replace)	poner	repuesto
predecir (to predict)	decir	predicho

The pattern is reliable: if the root verb is irregular, every compound verb on that root shares the irregular form.

Accent marks on some -ido forms

When a regular -ido ending follows a vowel in the stem, an accent mark is required to separate the syllables and prevent them from merging into a diphthong.

Infinitive	Past participle	Without accent (wrong)
leer	leído	leido
oír	oído	oido
caer	caído	caido
traer	traído	traido
creer	creído	creido
poseer	poseído	poseido

The accent mark is not optional. Leido and leído are different words (the first barely recognizable as a past participle in writing).

Past participles with haber: perfect tenses

The most common use of the past participle is in compound tenses formed with haber. In this context, the past participle is invariable, it does not change for gender or number regardless of the subject.

Tense	Formation	Example
Present perfect	haber (present) + past participle	He comido (I have eaten)
Past perfect	haber (imperfect) + past participle	Había comido (I had eaten)
Future perfect	haber (future) + past participle	Habré comido (I will have eaten)
Conditional perfect	haber (conditional) + past participle	Habría comido (I would have eaten)

The invariability rule: Nothing changes the past participle when it follows haber. He comido, hemos comido, han comido, the participle stays as comido regardless.

Past participles with estar: resulting states

Estar + past participle describes the state that results from a completed action. Here, the past participle agrees in gender and number with the noun it describes.

Spanish	English	State described
La puerta está abierta.	The door is open.	result of opening
Los libros están escritos.	The books are written.	result of writing
El vaso está roto.	The glass is broken.	result of breaking
La mesa está puesta.	The table is set.	result of setting
El problema está resuelto.	The problem is solved.	result of resolving

Contrast with ser: estar + past participle describes a state; ser + past participle describes a passive action.

Past participles with ser: passive constructions

Ser + past participle creates a passive voice construction. The past participle again agrees in gender and number with the subject.

El libro fue escrito por García Márquez. (The book was written by García Márquez.) Las cartas fueron enviadas ayer. (The letters were sent yesterday.) El proyecto será presentado la semana que viene. (The project will be presented next week.)

The passive with ser is more common in written and formal Spanish than in everyday spoken Spanish, where speakers tend to use active constructions or the se passive (se vendió el coche, the car was sold) instead.

Past participles as adjectives

Past participles function as adjectives when used independently (without haber or ser/estar). They agree in gender and number like any Spanish adjective.

Masculine singular	Feminine singular	Masculine plural	Feminine plural
un libro escrito	una carta escrita	libros escritos	cartas escritas
un hombre cansado	una mujer cansada	hombres cansados	mujeres cansadas
el problema resuelto	la situación resuelta	problemas resueltos	situaciones resueltas

Llegó agotado. (He arrived exhausted., participle as predicate adjective, agrees with masculine subject.) Las ventanas rotas necesitan reparación. (The broken windows need repair.)

Common mistakes

Error	Correct form	Note
he hacido	he hecho	hacer is irregular
he volvido	he vuelto	volver is irregular
he rompido	he roto	romper is irregular
he veido / he vido	he visto	ver is irregular
ella ha comida	ella ha comido	invariable after haber, no -a ending
leido (no accent)	leído	accent required when -ido follows a vowel
la puerta es abierta (state)	la puerta está abierta	use estar for resulting states

Building past participle fluency

The test of whether these forms are automatic is whether they appear correctly under conversational pressure, in compound tenses describing real events, not just in isolated drills.

Book a trial lesson and tell your teacher about the last week: what you have done, seen, eaten, written, broken. The conversational context forces past participles into actual use, and a teacher correcting hecho, visto, and escrito in real time is what makes the irregular forms automatic.

FAQ

How many irregular Spanish past participles are there?

Twelve core irregulars. Their compound verbs inherit the same irregular form, which extends the set significantly, but all the compounds follow from the same twelve roots.

Why doesn’t the past participle agree in the perfect tenses?

When used with haber, the past participle is frozen in its masculine singular form. This is a historical development in Spanish grammar, originally it could agree, but standard Spanish fixed it as invariable in compound tenses. The agreement rule applies only when the participle functions as a standalone adjective or appears with estar or ser.

What is the difference between está roto and fue roto?

Está roto (with estar) describes a resulting state: the thing is currently broken. Fue roto (with ser) describes a passive action: it was broken (by something or someone). In practice, está roto appears far more often in everyday speech.

Is freír – frito really irregular?

Yes. Freír is the most frequently ignored irregular. Some speakers use freído, which exists but is less common; frito is the standard form, particularly in adjectival use (patatas fritas, fried potatoes).
