Romanian's past participle (scris, mers, închis, construit) is one form that lives two lives, and the only thing you ever need to decide is which life it is leading in a given sentence. If it is doing tense work — building a compound tense or mood with the auxiliary a avea — it is frozen: am scris, ați mers, vom fi terminat. If it is doing passive or adjective work — sitting after a fi or modifying a noun — it agrees in gender and number: o scrisoare scrisă, uși închise, casa a fost construită. That is the entire rule. This page lays it out as one decision, walks each role, and handles the one genuine wrinkle: the feminine direct-object clitic -o, which forces agreement even inside the perfect compus.
The one question
Before you ever wonder whether to add -ă, -i, or -e to a participle, ask yourself a single question:
Is this participle building a tense, or is it a passive / an adjective?
- Tense (with a avea: am, ai, a, am, ați, au) → FROZEN. It stays in the bare masculine-singular form for every subject and object.
- Passive (with a fi) or adjective (modifying a noun) → AGREES. It takes adjective endings -Ø / -ă / -i / -e to match its noun.
Role 1: Tense — frozen with a avea
The perfect compus (am scris "I wrote") and every compound mood built on a avea keep the participle invariable. It does not matter whether the subject is masculine, feminine, singular, or plural; it does not matter what the object is. The participle sits in its base form and never moves.
| Subject | Perfect compus | English |
|---|---|---|
| el (m. sg.) | a scris | he wrote |
| ea (f. sg.) | a scris | she wrote |
| ei (m. pl.) | au scris | they wrote |
| ele (f. pl.) | au scris | they wrote |
Scris never becomes *scrisă or *scrise here. The auxiliary a avea freezes it.
Ana a scris trei mesaje, dar n-a primit niciun răspuns.
Ana wrote three messages but didn't get any reply. (a scris frozen, though Ana is feminine)
Fetele au mers pe jos până acasă.
The girls walked home. (au mers frozen, though 'fetele' is feminine plural)
Ați terminat proiectul la timp?
Did you finish the project on time?
This frozen behavior extends to all a avea-based compounds: the pluperfect colloquial (am avut scris is not standard, but the analytic moods like the perfect conditional aș fi scris and the future perfect voi fi scris freeze the participle just the same — because the participle there pairs with a fi as a perfect auxiliary, not as a copula). The takeaway: when the participle is part of a tense, it is frozen.
Role 2: Passive — agrees with the subject (with a fi)
The moment a fi is acting as a copula linking a subject to a state — that is, in the a fi passive — the participle behaves like a predicate adjective and agrees with the subject. This is the construction English speakers most often get wrong, because English passives never inflect the participle ("is written / are written" both use written).
| Subject | Passive | English |
|---|---|---|
| romanul (m. sg.) | a fost scris | the novel was written |
| scrisoarea (f. sg.) | a fost scrisă | the letter was written |
| blocurile (n. pl.) | au fost construite | the buildings were built |
| ușile (f. pl.) | au fost vopsite | the doors were painted |
Scrisoarea a fost scrisă de mână, nu la calculator.
The letter was written by hand, not on a computer. (scrisă agrees, fem. sg.)
Blocurile au fost construite în anii '70.
The apartment blocks were built in the '70s. (construite agrees, neut. pl.)
Toate ferestrele au fost închise înainte de furtună.
All the windows were closed before the storm. (închise agrees, fem. pl.)
The participle agrees with the subject, never the agent: in Florile au fost udate de grădinar ("The flowers were watered by the gardener"), udate is feminine plural to match florile, not masculine to match grădinar.
Role 3: Adjective — agrees with its noun
When the participle modifies a noun directly — o scrisoare scrisă de mână, uși închise — it is a plain adjective and takes the standard four-way endings -Ø / -ă / -i / -e, exactly like frumos / frumoasă / frumoși / frumoase. See the participle as adjective for the full paradigm.
Am primit o scrisoare scrisă de mână, ceva foarte rar azi.
I got a hand-written letter, something very rare these days. (scrisă agrees with scrisoare)
Magazinele închise duminica mă enervează.
Shops closed on Sundays annoy me. (închise agrees with magazinele)
Pereții proaspăt vopsiți miroseau a vopsea.
The freshly painted walls smelled of paint. (vopsiți agrees, masc. pl.)
The wrinkle: feminine direct-object -o in the perfect compus
Here is the one place where the "tense = frozen" rule bends. When a feminine singular direct object is expressed by the clitic -o, that clitic attaches to the end of the perfect-compus participle, and the participle then takes a feminine -t form. Compare:
| Object | Perfect compus | English |
|---|---|---|
| îl (m. sg.) | l-am văzut | I saw him |
| îi (m. pl.) | i-am văzut | I saw them (m.) |
| le (f. pl.) | le-am văzut | I saw them (f.) |
| o (f. sg.) | am văzut-o | I saw her |
Only the feminine singular o sits after the participle (am văzut-o), unlike every other clitic, which sits before the auxiliary (l-am văzut, le-am văzut). The participle itself does not visibly change for văzut (it ends in -t either way), but with this clitic the form is fixed and the -o is enclitic. This is not really gender agreement on the participle — it is a clitic-placement quirk — but learners experience it as "the participle changing for the feminine object," so it belongs here.
Am văzut-o ieri la piață, arăta foarte bine.
I saw her yesterday at the market, she looked great.
Cartea? Am citit-o de două ori.
The book? I've read it twice. (cartea is feminine → -o attaches to the end)
Am întâlnit-o pe Maria în parc.
I ran into Maria in the park.
Common Mistakes
❌ Ana a scrisă o scrisoare.
Incorrect — in the perfect compus the participle is FROZEN: 'a scris', even though Ana is feminine. Agreement here is tense work, not adjective work.
✅ Ana a scris o scrisoare.
Ana wrote a letter.
❌ Scrisoarea a fost scris de mână.
Incorrect — the passive agrees with the subject; feminine 'scrisoarea' needs 'scrisă'.
✅ Scrisoarea a fost scrisă de mână.
The letter was written by hand.
❌ uși închis
Incorrect — as an adjective the participle must agree; feminine plural 'uși' needs 'închise'.
✅ uși închise
closed doors
❌ Florile au fost udat de grădinar.
Incorrect — the passive participle agrees with the subject 'florile' (fem. pl.): 'udate'.
✅ Florile au fost udate de grădinar.
The flowers were watered by the gardener.
❌ Am o-văzut ieri. / O am văzut ieri.
Incorrect — feminine 'o' attaches to the END of the participle in the perfect compus: am văzut-o.
✅ Am văzut-o ieri.
I saw her yesterday.
Key Takeaways
- The whole of participle agreement collapses into one question: tense or passive/adjective?
- Tense (perfect compus and a avea compounds): the participle is frozen — am scris, au mers, ați terminat — regardless of subject or object.
- Passive (a fi copula): the participle agrees with the subject — scrisoarea a fost scrisă, blocurile au fost construite.
- Adjective (modifying a noun): the participle agrees with its noun — o scrisoare scrisă, uși închise.
- The lone exception inside the perfect compus is the feminine singular clitic o, which hooks onto the end of the participle: am văzut-o, am citit-o.
