An absolute construction is a participle or gerund phrase that has its own subject and stands detached from the main clause, set off by a comma. It compresses an entire "after / once / since X happened" clause into two or three words. Where everyday Portuguese says Depois que a reunião terminou, fomos embora, the elevated written register says Terminada a reunião, fomos embora — "The meeting over, we left." This page shows how the construction is built, why the participle changes form, and where it belongs.
What makes a construction "absolute"
A construction is absolute when it satisfies three conditions:
- It uses a non-finite verb — a past participle or a gerund.
- It has its own subject, separate from the main clause.
- It is syntactically detached, normally placed at the front of the sentence and marked off by a comma.
Terminada a reunião, fomos embora.
The meeting over, we left.
Here a reunião is the subject of terminada, while nós (implied) is the subject of fomos. The participle clause is not embedded in the main clause — it floats in front of it, supplying the time frame.
This is firmly formal, written, and literary register: news articles, essays, fiction, legal and academic prose. In conversation Brazilians replace it with a quando or depois que clause. Recognizing it is essential for reading; producing it marks polished writing.
Participial absolutes — the core type
A past participle teams up with a noun (its subject). The defining feature is agreement: the participle changes its ending to match the gender and number of that noun, exactly as an adjective would.
| Noun | Gender / number | Participle | Construction |
|---|---|---|---|
| o jogo | masc. sg. | terminado | Terminado o jogo, ... |
| a reunião | fem. sg. | terminada | Terminada a reunião, ... |
| os exames | masc. pl. | corrigidos | Corrigidos os exames, ... |
| as cartas | fem. pl. | escritas | Escritas as cartas, ... |
Terminado o jogo, os torcedores invadiram o campo.
Once the game ended, the fans rushed onto the field.
Corrigidas as provas, a professora divulgou as notas.
Once the exams were graded, the teacher released the grades.
Feito isso, ele saiu sem dizer mais nada.
That done, he left without saying another word.
Word order and meaning
The natural order is participle + noun (Terminada a reunião), which is the marked, literary pattern. The participle's most common reading is temporal: one event finished, then the next happened ("once / after X was done"). It can also be lightly causal ("X having been the case, …"). Many fixed connectors come straight from this type — feito isso (this done), dito isso (that said), posto isso (this being established).
Assinado o contrato, não há mais volta atrás.
Once the contract is signed, there's no turning back.
Dito isso, passemos ao próximo assunto.
That said, let's move on to the next topic.
Irregular participles appear here
Because the absolute construction is built on the past participle, the irregular participles show up in their full irregular form — and still agree:
Aberta a votação, os deputados começaram a se manifestar.
Once voting was opened, the deputies began to speak up.
Postas as cartas na mesa, a negociação finalmente avançou.
With the cards laid on the table, the negotiation finally moved forward.
Note aberta (from abrir) and postas (from pôr) — irregular participles that nonetheless take the feminine/plural agreement endings.
Gerund absolutes
The gerund can also head an absolute construction. Instead of a completed prior action, it expresses a simultaneous circumstance or a state of affairs — "X being the case." The gerund itself never agrees (it has no gender or number), but it carries its own subject.
Sendo assim, eu concordo com a proposta.
That being so, I agree with the proposal.
Estando tudo pronto, podemos começar.
Everything being ready, we can begin.
Não havendo mais perguntas, encerro a reunião.
There being no further questions, I'll close the meeting.
Sendo assim ("that being so / therefore") is by far the most common gerund absolute and has become a near-fixed connector; you will hear it even in semi-formal speech. The others (estando tudo pronto, não havendo dúvidas) stay closer to the written register.
Why the participle agrees (the underlying logic)
The agreement isn't arbitrary. In an absolute construction the participle behaves like a predicate adjective describing its subject: a reunião is "[now] terminated," as cartas are "[now] written." Adjectives agree with their nouns in Portuguese, and the participle in this slot is functioning adjectivally. The moment the same participle is locked into a compound tense after ter or haver, it stops being adjectival and freezes — which is exactly why it no longer agrees there. Tracking what the participle is describing tells you whether to inflect it.
Register: formal absolute vs. everyday clause
| Absolute (formal / written) | Finite clause (everyday) |
|---|---|
| Terminada a aula, fomos almoçar. | Quando a aula terminou, fomos almoçar. |
| Feito isso, ele saiu. | Depois que fez isso, ele saiu. |
| Sendo assim, concordo. | Como é assim, eu concordo. |
| Não havendo dúvidas, prossigo. | Como não há dúvidas, prossigo. |
The fixed expressions — sendo assim, dito isso, feito isso — cross over into casual register, but the freely built absolutes (Corrigidas as provas, …) are reserved for writing and would sound stilted in a chat.
Common Mistakes
❌ Terminado a reunião, fomos embora.
Incorrect — 'reunião' is feminine, so the participle must agree: terminada.
✅ Terminada a reunião, fomos embora.
The meeting over, we left.
❌ Corrigido as provas, a professora divulgou as notas.
Incorrect — 'provas' is feminine plural; the participle must be corrigidas.
✅ Corrigidas as provas, a professora divulgou as notas.
Once the exams were graded, the teacher released the grades.
❌ Terminada a reunião, ela tinha terminada o relatório.
Incorrect — inside the compound tense the participle is invariable: tinha terminado.
✅ Terminada a reunião, ela tinha terminado o relatório.
The meeting over, she had finished the report.
❌ Sendo assim, terminado o jogo, os torcedores invadiu o campo.
Incorrect — the main verb must agree with its plural subject: invadiram.
✅ Terminado o jogo, os torcedores invadiram o campo.
Once the game ended, the fans rushed onto the field.
❌ Depois de terminada a reunião embora.
Incorrect — an absolute construction stands alone; don't bolt a preposition onto it. Use either the absolute or a finite clause, not a fragment.
✅ Terminada a reunião, fomos embora.
The meeting over, we left.
Key Takeaways
- An absolute construction has its own subject, uses a non-finite verb (participle or gerund), and is detached by a comma.
- The participle agrees in gender and number with its noun — because it works like a predicate adjective; inside compound tenses it stays invariable.
- Participle absolutes mark a completed prior action (Terminada a reunião); gerund absolutes mark a circumstance (Sendo assim).
- This is elevated written / literary Portuguese; in speech, swap in a quando or depois que clause — except the fixed connectors sendo assim, dito isso, feito isso.
