Talvez ("perhaps," "maybe") is one of the highest-frequency subjunctive triggers in spoken Brazilian Portuguese. You will hear it dozens of times a day, and almost every time it appears before the verb, that verb is in the subjunctive. The logic is clean: talvez introduces doubt, and doubt is the native habitat of the subjunctive. But talvez has one quirk no other trigger shares — its effect depends on where in the sentence it sits. That positional sensitivity is what this page is really about.
The basic rule: talvez before the verb → subjunctive
When talvez precedes the verb, the verb is subjunctive. This is because talvez explicitly marks the action as uncertain — it isn't a fact, it's a possibility, and possibilities live in the subjunctive.
Talvez ele venha amanhã.
Maybe he'll come tomorrow.
Talvez eu não consiga chegar a tempo.
Maybe I won't manage to get there in time.
Talvez seja melhor a gente ligar antes.
Maybe it's better for us to call first.
Notice venha, consiga, seja — all present subjunctive. An English speaker's instinct is to say Talvez ele vem, copying the indicative "Maybe he comes." That instinct is wrong; the doubt in talvez demands the subjunctive.
Tense follows the timeframe
Talvez doesn't lock you into the present subjunctive — it triggers whatever subjunctive tense the meaning requires. For past possibilities, use the imperfect subjunctive.
Talvez ela já tivesse saído quando você ligou.
Maybe she had already left when you called.
Talvez fosse melhor a gente ter avisado.
Maybe it would have been better for us to have warned them.
Here tivesse and fosse are imperfect/pluperfect subjunctive, matching the past reference. The trigger is the same; only the tense shifts to fit the timeframe.
The positional quirk: talvez after the verb → indicative
This is where talvez breaks ranks with every other subjunctive trigger. When talvez comes after the verb — often tacked onto the end of the sentence, as an afterthought — the verb is in the indicative.
Ele vem amanhã, talvez.
He's coming tomorrow, maybe.
A gente vai sair mais cedo hoje, talvez.
We're going to leave earlier today, maybe.
Why? When talvez trails the clause, the speaker has essentially asserted the statement first ("He's coming tomorrow") and then softened it with a hedge ("...maybe"). The verb was uttered as a near-assertion, so it stays indicative; the doubt arrives only afterward. Compare this to the front-loaded version, where the doubt frames the entire clause from the start and pulls the verb into the subjunctive.
Talvez ele venha amanhã.
Maybe he'll come tomorrow. (doubt frames the whole clause → subjunctive)
Ele vem amanhã, talvez.
He's coming tomorrow, maybe. (assertion first, hedge after → indicative)
This is genuinely unusual. Most subjunctive triggers — quero que, embora, é possível que — don't move around like this, and their effect never depends on position. Talvez is the one common word whose mood selection is positional, which is exactly why it trips learners up.
What careful speakers actually do
In careful or formal speech, many Brazilians use the subjunctive with talvez regardless of its position — they'll even say Ele venha amanhã, talvez with the subjunctive, because they treat talvez as an inherent doubt-marker that "should" govern the verb wherever it lands. So you'll encounter three patterns in the wild:
| Sentence | Position of talvez | Verb mood | Register |
|---|---|---|---|
| Talvez ele venha. | before | subjunctive | standard, all registers |
| Ele vem, talvez. | after | indicative | colloquial, conversational |
| Ele venha, talvez. | after | subjunctive | careful / formal speech |
For production, you do not need the third pattern — stick with the first. But you should recognize all three when you hear them.
Synonyms that behave the same way
Talvez has near-synonyms that also trigger the subjunctive when they front the clause: possivelmente (possibly), provavelmente (probably, though weaker), and quiçá (perhaps — literary/formal, rare in speech).
Possivelmente eles cheguem atrasados por causa do trânsito.
They'll possibly arrive late because of the traffic.
Note that com certeza (certainly) and acho que (I think) do not trigger the subjunctive — they assert rather than doubt: Acho que ele vem amanhã (indicative). The dividing line is always the same: assertion takes the indicative, genuine doubt takes the subjunctive.
Common Mistakes
❌ Talvez ele vem amanhã.
Incorrect — talvez before the verb requires the subjunctive, not the indicative.
✅ Talvez ele venha amanhã.
Maybe he'll come tomorrow.
❌ Talvez eu vou viajar no fim de semana.
Incorrect — 'vou' is indicative; use the subjunctive after fronted talvez.
✅ Talvez eu viaje no fim de semana.
Maybe I'll travel this weekend.
❌ Talvez ele tinha saído já.
Incorrect — past doubt needs the pluperfect subjunctive, not the indicative.
✅ Talvez ele tivesse saído já.
Maybe he had already left.
❌ Acho que ele venha amanhã.
Incorrect (over-correction) — 'acho que' asserts an opinion, so it takes the indicative 'vem', not the subjunctive.
✅ Acho que ele vem amanhã.
I think he's coming tomorrow.
Key Takeaways
- Talvez before the verb → subjunctive. This is the default; always use it.
- Talvez after the verb → indicative in everyday speech (assertion first, hedge second).
- Careful/formal speakers may keep the subjunctive even with trailing talvez — recognize it, but you don't need to produce it.
- Talvez is the one common trigger whose mood depends on position — every other trigger forces the subjunctive regardless.
- Match the subjunctive tense to the timeframe: present (venha) for present/future doubt, imperfect (viesse, fosse) for past doubt.
