Portuguese Irregular Participles: 'Aceito' or 'Aceitado'?
Grammar Rule in 30 Seconds
Use 'aceito' with 'ser' or 'estar' (passive), and 'aceitado' with 'ter' or 'haver' (active).
- Use the irregular form (aceito) with 'ser' or 'estar': 'O convite foi aceito.'
- Use the regular form (aceitado) with 'ter' or 'haver': 'Eu tinha aceitado o convite.'
- Remember that 'aceito' acts as an adjective: 'Um pedido aceito.'
Overview
At the B2 level, your command of Portuguese is shifting from simply conveying meaning to expressing it with precision and nuance. One of the most significant hurdles in this transition is mastering verbos abundantes (abundant verbs) — verbs that possess two valid past participles. The choice between a regular form, like aceitado, and an irregular one, like aceito, is not a matter of style but a strict grammatical rule.
It's a distinction that separates proficient intermediate speakers from truly advanced ones.
This phenomenon isn't random; it's a core feature of the language's grammar that encodes the difference between an action in progress and a resulting state. The central principle is straightforward: the auxiliary verb you use dictates which participle form is correct. Using the active voice auxiliaries ter or haver triggers the regular participle to describe the doing of an action.
Using the state/passive auxiliaries ser or estar triggers the irregular participle to describe the result of that action. Understanding this logic is essential for correctly forming compound tenses and the passive voice, making your Portuguese more accurate and sophisticated.
How This Grammar Works
pago, aberto, escrito) are descendants of Latin's "strong" participles, which were formed through internal vowel changes and often had unique stems. They are ancient and deeply embedded in the language.-ado or -ido are a more modern, logical development, created by applying a consistent rule to verbs by analogy. Modern Portuguese preserves both, assigning them different grammatical roles.ter/haver + Regular Participle)ter (to have) or, more formally, haver. In these constructions, you must use the long, regular past participle (e.g., entregado, imprimido). This form emphasizes the action itself.-o and never changes for gender or number, regardless of the subject or object.Ela já tinha limpado a casa quando chegamos.(She had already cleaned the house when we arrived.) -limpadois regular and invariable.Se eu tivesse aceitado a oferta, estaria em outra cidade.(If I had accepted the offer, I'd be in another city.) -aceitadois regular and invariable.
ser/estar + Irregular Participle)ser (to be, for passive voice) or estar (to be, for states). In these cases, you must use the short, irregular past participle (e.g., entregue, impresso). Here, the participle functions exactly like an adjective.A casa estava limpa quando chegamos.(The house was clean when we arrived.) -limpais irregular and agrees witha casa(feminine singular).A oferta foi aceita por unanimidade.(The offer was accepted unanimously.) -aceitais irregular and agrees witha oferta(feminine singular).
Eu tinha acendido a luz (I had turned on the light) describes your past action. A luz estava acesa (The light was on) describes the resulting state of the light.Formation Pattern
falar -> falado, vender -> vendido), a critical group of common verbs has two.
verbos abundantes
entregar (to deliver) |
ter / haver | Regular (long form, -ado/-ido) | Invariable (always masculine singular) | Ele tinha entregado os pacotes. |

-ido participle. They only have one form—the irregular one. For these verbs, you use the same irregular participle with all auxiliaries (ter, haver, ser, estar). However, the rule of agreement still applies: the participle remains invariable with ter/haver but agrees in gender and number with ser/estar.
ter: Eu já tinha escrito o email. (escrito is invariable)
ser: O email foi escrito por mim. (escrito agrees with o email)
estar: As paredes estão cobertas de poeira. (cobertas agrees with as paredes)
abrir (to open) | aberto |
cobrir (to cover) | coberto |
dizer (to say) | dito |
escrever (to write) | escrito |
fazer (to do/make) | feito |
pôr (to put) | posto |
ver (to see) | visto |
vir (to come) | vindo |
fazido or abrido, which are non-existent in standard Portuguese.
When To Use It
-ado/-ido) when forming perfect tenses with the auxiliary ter (or haver). These tenses describe an action completed by the subject.- Pretérito Perfeito Composto (Present Perfect): Describes an action that started in the past and continues or has relevance to the present.
Ultimamente, eu tenho limpado o apartamento todos os sábados.(Lately, I have cleaned the apartment every Saturday.)
- Pretérito Mais-que-perfeito Composto (Past Perfect): Describes an action that occurred before another past action.
O suspeito já tinha salvado os arquivos quando a polícia chegou.(The suspect had already saved the files when the police arrived.)
- Futuro do Presente Composto (Future Perfect): Describes an action that will be completed by a certain point in the future.
Até o final do ano, eles terão imprimido todos os manuais.(By the end of the year, they will have printed all the manuals.)
limpado, salvado, and imprimido are the only correct choices. Using limpo, salvo, or impresso would be a grammatical error.ser, estar, or sometimes ficar.- Passive Voice with
ser: Describes an action being done to the subject. O novo presidente foi eleito com uma margem pequena.(The new president was elected by a small margin.)As joias roubadas nunca foram salvas.(The stolen jewels were never recovered/saved.)
- Resulting States with
estarorficar: Describes a condition or state. Quando voltei, as luzes estavam acesas.(When I got back, the lights were on.)Ele ficou preso no trânsito por duas horas.(He got stuck/imprisoned in traffic for two hours.)A roupa está seca e pronta para guardar.(The clothing is dry and ready to be put away.)
eleito, salvas, acesas, preso, seca) all agree with the subject they describe.Pagar, Ganhar, and Gastarpagar (to pay), ganhar (to win), and gastar (to spend). While the formal rule demands pagado, ganhado, and gastado with ter/haver, in modern spoken Portuguese (especially in Brazil), the irregular forms pago, ganho, and gasto are overwhelmingly preferred in the active voice as well.Eu já tinha pago a conta.(I had already paid the bill.) - This is far more common in Brazil thantinha pagado.Eles tinham ganho o campeonato no ano anterior.(They had won the championship the previous year.) -ganhois very frequent here.
pagado, ganhado) is always grammatically correct and safer in formal writing, using the irregular forms (pago, ganho) with ter is widely accepted and often sounds more natural in daily conversation. For all other abundant verbs, however, the traditional rule remains firm.Common Mistakes
ter/haverser/estar.- Incorrect:
*Eu já tinha impresso os documentos. - Correct:
Eu já tinha imprimido os documentos. - Why it's wrong: The auxiliary
tersignals an active voice construction, which requires the regular, invariable participleimprimido.
ser/estar-ado/-ido ending in a context that demands the irregular form.- Incorrect:
*O fogo foi acendido pelo menino. - Correct:
O fogo foi aceso pelo menino. - Why it's wrong: The auxiliary
sersignals the passive voice, which requires the irregular participleaceso.Acendidocan only be used withterorhaver.
ser/estar but forget that it must function like an adjective and agree with the subject.- Incorrect:
*As cartas foram entregue hoje. - Correct:
As cartas foram entregues hoje. - Why it's wrong:
Cartasis feminine and plural, so the participle must also be feminine and plural (entregues). The invariable form is only for active tenses withter.
-ido pattern to verbs that don't have it.- Incorrect:
Eu não tinha abrido a janela.orEle tinha escrevido um livro. - Correct:
Eu não tinha aberto a janela./Ele tinha escrito um livro. - Why it's wrong: Verbs like
abrir,escrever,fazer, andpôrdo not have regular participles.Abertoandescritoare the only forms and are used with all auxiliaries.

Analysis
foi entregue (passive with ser + irregular) because her focus is on the report's status. Tiago responds with tinha entregado (active with ter + regular) because his focus is on his action of delivering it.*Scenario 2
Ana (21:30): A louça já foi limpa? Queria usar a cozinha.
Marcos (21:31): Foi mal, ainda não. Eu não tinha limpado porque achei que vc ia usar primeiro.
Ana (21:31): Blz. Deixa que eu lavo então.
Analysis
foi limpa? (passive voice) to inquire about the state of the dishes. Marcos replies with tinha limpado (active voice), explaining the action he failed to perform.*Scenario 3
- Pai: Filho, a TV ficou acesa a noite inteira! Você não tinha apagado antes de dormir?
- Filho: Ué, eu achei que tinha apagado. Devo ter me enganado.
Analysis
ficou acesa. He then questions the son's past action using tinha apagado (from apagar, a regular verb, showing the pattern is universal). The son defends his action using the same structure tinha apagado.*Quick FAQ
aceitado just plain wrong then?Not at all. Aceitado is perfectly correct, but only when used with the active auxiliaries ter or haver. For example, Ele não tinha aceitado minhas desculpas. The form that's wrong is using it with ser or estar, as in *A proposta foi aceitado.
chegar? I hear people say tinha chego. Is that right?This is a classic point of confusion. The only standard, grammatically correct past participle for chegar is chegado. You should say eu tinha chegado. The form chego is the first-person present tense (eu chego). The use of tenho chego or tinha chego is a widespread informal variant in Brazil but is considered non-standard and should be avoided in writing and formal situations.
You don't need to know all of them. Start with the high-frequency list in the 'Formation Pattern' section. Focus on aceitar, entregar, imprimir, limpar, pagar, and salvar, as they cover many daily situations. Also, master the small list of verbs with only an irregular participle (abrir, escrever, fazer, etc.), as they are extremely common.
The fundamental rule is identical in both variants. The primary difference lies in the increasing acceptance of using the irregular forms of pagar, ganhar, and gastar with ter/haver in Brazil (tinha pago), which sounds more natural there than in Portugal, where tinha pagado is often still preferred in formal contexts. The use of tinha chego is also much more a feature of informal Brazilian Portuguese.
Yes. Create a mental link: ter/haver are verbs of ACTION. Actions take time, so they use the LONG form (-ado/-ido). Ser/estar are verbs of STATE or RESULT. A result is a fixed point, so it uses the SHORT, adjectival form. Action = Long Form. State = Short Form.
