Participio Passato: Regular Formation | Italian Grammar

The regular past participle is one of the most cooperative pieces of Italian morphology. Each conjugation class has a single suffix, the stress is always on the suffix, and the form inflects in the most ordinary way for any Italian word ending in -o — into -o / -a / -i / -e for masculine singular, feminine singular, masculine plural, feminine plural. Once you have the suffixes, you have the participle of every regular verb in the language.

The catch is that the -ere class, while looking simple on paper (-uto), is the only class where most high-frequency verbs don't follow the regular pattern. We'll address that on the irregular page. This page deals with the orderly cases.

The three suffixes

To form a regular past participle, drop the infinitive ending and add the class-specific suffix.

Class	Drop	Add	Example	Stress
-are	-are	-ato	parlare → parlato	par-là-to
-ere	-ere	-uto	credere → creduto	cre-dù-to
-ire	-ire	-ito	dormire → dormito	dor-mì-to

The stress always falls on the vowel of the suffix — the second-to-last syllable. There are no rizotonic exceptions here. Parlàto (not pàrlato), credùto (not crèduto), dormìto (not dòrmito). This is the natural Italian default and rarely a problem for learners.

The -are class: almost completely regular

The -are conjugation is the engine of Italian word formation. New verbs join this class (chattare → chattato, postare → postato, googlare → googlato), and almost without exception they form their participle in -ato. There are only a tiny handful of irregulars in the entire class — the most important being fare → fatto (which historically belongs to the -ere group anyway) and stare → stato.

Infinitive	Meaning	Past Participle
parlare	to speak	parlato
mangiare	to eat	mangiato
lavorare	to work	lavorato
comprare	to buy	comprato
guardare	to watch	guardato
amare	to love	amato
aspettare	to wait	aspettato
arrivare	to arrive	arrivato
cominciare	to start	cominciato
cercare	to look for	cercato

Ho parlato con il direttore stamattina.

I spoke with the director this morning.

Abbiamo mangiato troppo, sono pieno.

We ate too much, I'm stuffed.

Ti ho aspettato per più di un'ora.

I waited for you for more than an hour.

Notice that the -ato form is invariable when the auxiliary is avere (as in all three examples above), but it inflects normally when essere is involved or when the participle behaves as an adjective. The form mangiato can become mangiata, mangiati, mangiate — exactly like any other word ending in -o.

The -ire class: the most regular of all

The -ire class is even more reliable than -are. Out of the few hundred -ire verbs in the language, only a small group has irregular participles (aprire → aperto, offrire → offerto, morire → morto, venire → venuto, dire → detto). Everything else takes -ito without surprise.

Infinitive	Meaning	Past Participle
dormire	to sleep	dormito
finire	to finish	finito
sentire	to hear / feel	sentito
partire	to leave	partito
capire	to understand	capito
preferire	to prefer	preferito
pulire	to clean	pulito
servire	to serve	servito
seguire	to follow	seguito

Non ho dormito quasi niente stanotte.

I barely slept at all last night.

Hai capito quello che ha detto il professore?

Did you understand what the professor said?

Sono partita alle sei di mattina.

I left at six in the morning. (female speaker)

The -isco subgroup of -ire verbs (finire, capire, preferire, pulire) — the ones that insert -isc- in the present indicative — does not insert anything in the participle. It's just -ito, completely regular.

The -ere class: the regular minority

Here is where the trouble starts. The -ere class is the only class where the regular form (-uto) is the minority pattern for high-frequency verbs. Most -ere verbs you'll meet at A1–B1 are irregular: prendere → preso, scrivere → scritto, leggere → letto, mettere → messo, chiudere → chiuso, and dozens more.

However, the regular -uto form is alive and productive for a meaningful set of verbs — many of which are extremely common.

Infinitive	Meaning	Past Participle
credere	to believe	creduto
vendere	to sell	venduto
ricevere	to receive	ricevuto
potere	to be able to	potuto
dovere	to have to	dovuto
sapere	to know	saputo
volere	to want	voluto
tenere	to hold	tenuto
battere	to beat	battuto
cadere	to fall	caduto

Ho dovuto cancellare la cena.

I had to cancel dinner.

Hanno venduto la casa la settimana scorsa.

They sold the house last week.

Non ho mai creduto a quella storia.

I've never believed that story.

💡

The four modal verbs — potere, dovere, volere, sapere — all have regular -uto participles (potuto, dovuto, voluto, saputo). This is a real piece of luck: these are among the most frequent verbs in the language, and they behave themselves.

A trap inside the regular -uto group

A few -ere verbs look like they should be regular but aren't. The most important is vivere (to live), whose participle is the irregular vissuto, not vivuto. Another is rimanere (to remain) → rimasto, not rimanuto. And piacere (to like) → piaciuto, which is regular but inserts an extra i (more on the irregular page).

Ho vissuto a Roma per cinque anni.

I lived in Rome for five years.

Sono rimasto a casa tutto il giorno.

I stayed home all day.

Mi è piaciuto moltissimo quel film.

I really liked that movie.

If you want a productive heuristic for -ere verbs: assume irregular until proven otherwise. The handful of verbs in the table above are the ones you can rely on.

Inflection: -o, -a, -i, -e

The citation form (-ato, -uto, -ito) is the masculine singular. Like every Italian word ending in -o, the past participle inflects for gender and number when the grammatical role calls for it.

	Masculine	Feminine
Singular	parlato, creduto, dormito	parlata, creduta, dormita
Plural	parlati, creduti, dormiti	parlate, credute, dormite

When does it inflect, and when does it stay invariable? That's the agreement question — see the overview page for the full rule. The short version:

With essere (compound tenses, passives): agrees with the subject.
With avere (compound tenses): invariable — except with a preceding direct-object clitic.
As an adjective: agrees with the noun it modifies.

Marco è arrivato in ritardo.

Marco arrived late. (essere → masculine singular -o)

Lucia è arrivata in ritardo.

Lucia arrived late. (essere → feminine singular -a)

I ragazzi sono arrivati in ritardo.

The boys arrived late. (essere → masculine plural -i)

Le ragazze sono arrivate in ritardo.

The girls arrived late. (essere → feminine plural -e)

Marco ha mangiato la pizza.

Marco ate the pizza. (avere → invariable -o regardless of object gender)

Forming compound tenses

The participle is the second piece of every compound tense. The auxiliary carries the person and tense; the participle carries the lexical meaning. Choose the right auxiliary, conjugate it, append the participle, apply agreement.

Tense	Auxiliary	Example (parlare)	Example (andare)
passato prossimo	present	ho parlato	sono andato/a
trapassato prossimo	imperfect	avevo parlato	ero andato/a
futuro anteriore	future	avrò parlato	sarò andato/a
condizionale passato	conditional	avrei parlato	sarei andato/a
congiuntivo passato	congiuntivo present	che abbia parlato	che sia andato/a

Avrei dormito di più, ma il telefono ha squillato.

I would have slept longer, but the phone rang.

Spero che tu abbia capito tutto.

I hope you understood everything.

Common mistakes

❌ Ho parlàto con tua madre.

Incorrect stress placement — the suffix carries the stress, but it's parl-A-to (penultimate), not stressed in any unusual way; native speakers should never write the accent. The bigger mistake here is writing the accent at all.

✅ Ho parlato con tua madre.

I spoke with your mother. (No written accent — the regular penultimate stress needs no marking.)

❌ Ho prendato il treno alle otto.

Incorrect — prendere is irregular. There is no form *prendato.

✅ Ho preso il treno alle otto.

I took the train at eight.

❌ Ho vivuto a Milano.

Incorrect — vivere has the irregular participle vissuto, not the expected *vivuto.

✅ Ho vissuto a Milano.

I lived in Milan.

❌ Maria è andato al lavoro.

Incorrect — with essere, the participle agrees with the subject. Maria is feminine.

✅ Maria è andata al lavoro.

Maria went to work.

❌ Le ragazze hanno mangiate la pizza.

Incorrect — with avere and a normal full-noun object, no agreement. The participle stays mangiato.

✅ Le ragazze hanno mangiato la pizza.

The girls ate the pizza.

Key takeaways

Three regular suffixes cover the entire system: -ato for -are verbs, -uto for -ere verbs, -ito for -ire verbs. Stress always falls on the suffix vowel.

Three things to remember:

-are and -ire are reliably regular; you can form their participles by reflex.
-ere is the danger zone. Most high-frequency -ere verbs are irregular. Treat the -uto form as something you confirm verb by verb (and learn the irregulars on the dedicated page).
Inflection happens whenever the participle is describing something — a subject (with essere), a noun (as adjective), or a clitic-fronted object (with avere). When it's just sitting next to avere with no preceding clitic, it stays invariable in -o.

Next, see the irregular full list for the indispensable irregulars, then past participle as adjective for the productive non-verbal use.
