Sequence of Tenses (Past)
In Portuguese, if your main verb is in the past (Preterite, Imperfect, or Conditional), the subordinate verb must also shift into a past subjunctive form to maintain temporal harmony.
How It Works
The sequência de tempos verbais (Sequence of Tenses), formally known as Correlação Verbal, is a strict rule in standard Portuguese grammar. When a main clause uses a verb that triggers the subjunctive—whether expressing desire, doubt, emotion, or using impersonal expressions—and that verb is anchored in the past, the subordinate clause must follow suit. Note that in colloquial, spoken Brazilian Portuguese, native speakers sometimes relax this rule by mixing a past anchor with the Present Subjunctive (e.g., saying Queria que você faça isso instead of fizesse).
1. The Anchors:
The rule applies when the main verb is in the:
- Pretérito Perfeito (e.g., Pedi)
- Pretérito Imperfeito (e.g., Queria)
- Condicional / Futuro do Pretérito (e.g., Gostaria)
- Pretérito Mais-Que-Perfeito (e.g., Tinha pedido)
Warning: The Pretérito Perfeito Composto (e.g., Tenho pedido) acts as a present anchor and triggers the Present Subjunctive, not the past.
2. The Subordinate Tenses:
Depending on when the second action happened relative to the first, you choose between:
- Imperfect Subjunctive: For actions happening at the same time or after the main verb. This includes the endings -asse, -asses, -asse, -ássemos, -ásseis, -assem, -esse, -esses, -esse, -êssemos, -êsseis, -essem, and -isse, -isses, -isse, -íssemos, -ísseis, -issem. Note that the Imperfect Subjunctive stem is derived from the 3rd person plural of the Pretérito Perfeito (e.g., dropping the '-ram' from fizeram to form fizesse).
- Pluperfect Subjunctive: For actions that had already happened before the main verb (e.g., tivesse falado).
3. The Future Subjunctive Shift:
A critical part of this sequence is the 'downgrade' of the future axis. When a sentence using the Futuro do Subjuntivo (e.g., Se ele vier...) is moved into the past, it must change to the Imperfect Subjunctive (e.g., Se ele viesse...), and the main clause must also shift from Futuro do Presente to Condicional / Futuro do Pretérito (e.g., Se ele vier, eu ajudarei -> Se ele viesse, eu ajudaria).
4. Hypothetical 'Se' Clauses:
A core application of this rule is the strict pairing of the Imperfect Subjunctive with the Conditional / Futuro do Pretérito to express unreal or hypothetical situations in the present (e.g., Se eu tivesse dinheiro, eu compraria um carro).
5. Broad Triggers:
This correlation applies to all subjunctive triggers, including impersonal expressions like Era necessário que... and conjunctions like embora.
Examples (4)
- Eu pedi que ele fizesse o jantar.
I asked him to make dinner.
Word by Word: I asked that he might-make the dinner.
The main verb 'pedi' (Preterite) triggers the Imperfect Subjunctive 'fizesse' for a simultaneous/subsequent action.
- Eu duvidava que eles tivessem chegado cedo.
I doubted that they had arrived early.
Word by Word: I doubted that they had-might-have arrived early.
The main verb 'duvidava' (Imperfect) triggers the Pluperfect Subjunctive 'tivessem chegado' because the arrival happened before the doubting.
- Seria melhor que nós saíssemos agora.
It would be better if we left now.
Word by Word: It would-be better that we might-leave now.
The Conditional 'seria' acts as a past anchor, requiring the Imperfect Subjunctive 'saíssemos'.
- Ela não acreditou que eu fizesse aquilo.
She didn't believe that I would do that.
Word by Word: She not believed that I might-do that.
Even if the action is in the future relative to the 'believing', the past anchor 'acreditou' forces the Imperfect Subjunctive.
Common Mistakes
Using the Present Subjunctive after a Past Indicative verb.
Eu queria que você venha à festa.Eu queria que você viesse à festa.In Portuguese, you cannot mix the 'Present Axis' (venha) with the 'Past Axis' (queria). You must backshift to the Imperfect Subjunctive.
Using the Future Subjunctive with the Conditional.
Seria bom se você for comigo.Seria bom se você fosse comigo.The Conditional (seria) is part of the past sequence and requires the Imperfect Subjunctive (fosse), not the Future Subjunctive (for).
How It Connects
Learn This First
To learn the Sequence of Tenses in the past, you must first be comfortable with past indicative tenses (like the Pretérito Perfeito or Imperfeito) used in main clauses. You also need to know how to form the Imperfect Subjunctive, as this is the tense required in the subordinate clause when the main action is set in the past. Finally, understanding the general logic of how tenses 'match' between clauses (starting with the present sequence) is essential.
- -asse/-asses/-asse/-ássemos/-ásseis/-assemImperfeito Do Subjuntivo -AR
The learner must be able to conjugate the imperfect subjunctive, which is the core component of the subordinate clause in this sequence.
Level 4 - Sequence of Tenses (Present)
Understanding how tenses align in the present (Present Indicative + Present Subjunctive) is a necessary conceptual foundation for applying the same logic to past contexts.
Level 5 - Perfeito for Completion
The sequence of tenses in the past is triggered by a main clause in a past tense, such as the Pretérito Perfeito.
