Sequence of Tenses (Concordância Temporal)

When a Portuguese sentence has two clauses, the tense of the subordinate clause is not chosen in isolation — it is calibrated against the tense of the main clause. Grammarians call this concordância temporal, the sequence of tenses. It is the rule that turns quero que venhas (I want you to come) into queria que viesses (I wanted you to come) when the main verb moves into the past, and the rule that forces you to say disse que estava cansado, not disse que estou cansado, when reporting what someone said yesterday.

This is one of the points where English and Portuguese look similar on the surface and behave differently underneath. English has sequence of tenses too, but it is loose — "he said he is tired" and "he said he was tired" are both possible, with slightly different implications. Portuguese is stricter: the subordinate tense is normally locked to the main tense, and breaking the lock produces a sentence that sounds wrong to native ears, even if the meaning is clear. Mastering this rule is the difference between B1 and B2 Portuguese.

This page covers the full system: how the subordinate clause responds when the main verb is in the present, the past, or the future, across both the indicative and the subjunctive. For the specific mechanics of reported speech — which is one important application of sequence of tenses — see the tense shifts page. This page gives you the broader system, which governs noun clauses, adverbial clauses, and relative clauses of every kind.

The three anchor tenses

The main clause establishes a temporal anchor. Every anchor behaves differently, so it is useful to organise the rules by what the main verb is doing.

• Present anchor — main verb in present indicative, present perfect compound, or imperative. The subordinate tense matches real-world time directly.
• Past anchor — main verb in preterite, imperfect, pluperfect, or conditional. The subordinate tense normally shifts backward to stay consistent with the past perspective.
• Future anchor — main verb in future indicative or future with ir. The subordinate tense depends on the trigger: indicative for facts, subjunctive for conditions and temporal subordinates.

The sections below walk through each anchor in turn.

Present anchor: the subordinate clause stays put

When the main verb is in the present, the subordinate verb expresses its own time directly. A present subordinate describes simultaneous action. A past subordinate describes a prior event. A future subordinate describes a later event. No shift is needed, because the reference point for the listener is now and the subordinate clause can locate itself freely.

With indicative subordinates

All three sentences have the same present main verb diz, but the subordinate covers three different times. The subordinate tense does exactly what you'd expect from its meaning in isolation.

With subjunctive subordinates

When the main clause triggers the subjunctive (verbs of wishing, doubting, feeling emotion, impersonal expressions), the subjunctive tense aligns with the temporal relationship:

The choice of present subjunctive (venhas, saiba) versus present perfect subjunctive (tenha chegado) is driven by whether the event is present/future or already completed — not by the main verb, which is always present.

Past anchor: the backshift rule

This is the heart of concordância temporal and the point where Portuguese parts company with English. When the main verb is in the past — preterite, imperfect, pluperfect, or conditional — the subordinate clause normally shifts to a past-compatible tense, even if the original subordinate event is present or future from the speaker's current point of view.

Indicative shifts

Note the pattern: already-past tenses don't shift again, because there is nowhere further back to go. The imperfect is Portuguese's workhorse past-of-ongoing-state, and once the subordinate lands there it stays.

Subjunctive shifts

The subjunctive moves in parallel. A past main verb triggers the imperfect subjunctive (or pluperfect subjunctive for completed events) instead of the present subjunctive.

The future-in-the-past: when the "future" is the conditional

English says "he said he will come" or "he said he would come" almost interchangeably. Portuguese forces a choice: once the main verb is past, a future subordinate becomes the conditional. This is one of the main uses of the Portuguese conditional — it is not only about hypotheticals, it is also the default future-in-the-past.

In colloquial Portuguese, especially in Portugal, the imperfect often replaces the conditional here: disseram-nos que a estrada estava cortada até segunda is also heard. The conditional is more formal; the imperfect is more conversational.

When NOT to backshift

The backshift is the default, but it is overridden when the subordinate clause expresses an atemporal truth — something that was, is, and will be true regardless of the reporting moment.

Here gira (present indicative) stays, because the earth's orbit is a permanent fact. Writing girava would suggest the earth no longer does this — which would be absurd.

The name is still Beatriz; no need to shift. Compare with ela disse-me que a filha se chamava Beatriz, which implies the name might have changed since.

Future anchor: indicative or subjunctive depending on trigger

When the main verb is in the future, the subordinate clause follows one of two paths:

1. If the subordinate takes the indicative (noun clauses with que, most relative clauses), it stays in the indicative — usually present or future.
2. If the subordinate is introduced by a temporal or conditional conjunction (quando, se, assim que, logo que, enquanto), it takes the future subjunctive.

With indicative subordinates

With future subjunctive after conjunctions

The future subjunctive is one of Portuguese's signature tenses — a form most other Romance languages have lost or reserve for legal texts. In Portuguese it is alive and required after quando, se, assim que, logo que, sempre que, enquanto (in its "as long as" sense), conforme, and relative clauses with unknown antecedents.

The English translation uses present indicative (when you get home, if you need help) because English temporal and conditional clauses don't accept will. Portuguese goes in the opposite direction: it uses the future subjunctive precisely because the event is projected into the future and conditional on something.

Compound tense interactions

Sequence of tenses also governs how compound tenses align across clauses. The key rule: compound tenses shift their auxiliary, not their participle. If the main verb is past, a present perfect subordinate becomes pluperfect.

The pluperfect does not shift back further. Portuguese has no "super-pluperfect," so events prior to an already-past reference point stay pluperfect.

Conditional perfect in past contexts

When the anchor is past and the subordinate event is a future-perfect relative to that past anchor, the subordinate takes the conditional perfect:

The conditional perfect is also the tense that replaces the future perfect in reported speech: «Terei acabado amanhã» → Disse que teria acabado no dia seguinte.

Special case: the imperfect as narrative default

In narrative (especially in literary and journalistic writing), the imperfect often replaces the conditional even in formal contexts, because it feels less hypothetical and more factual. This is standard, not colloquial — compare:

Both are correct. The second is slightly more vivid and appears constantly in news writing.

Relative clauses: the hidden battleground

Sequence of tenses also applies to relative clauses, though the behaviour is subtler than in noun clauses. Two principles:

1. If the relative clause describes a specific, known referent, it uses the indicative and usually doesn't backshift — the referent is real regardless of time.
2. If the relative clause describes a hypothetical or unknown referent, it uses the subjunctive, and the subjunctive tense tracks the main clause.

In the first sentence, the woman exists — fala (indicative) stays present. In the second, the hypothetical person tracks the past main verb and sits in the imperfect subjunctive.

Subordinate adverbial clauses

Adverbial conjunctions behave consistently: the subordinate tense tracks the main tense through both indicative and subjunctive families.

Common Mistakes

English speakers often carry over English's loose sequence of tenses. Portuguese is stricter.

Using the present subjunctive after a past main verb is another widespread error — the subjunctive also has to shift.

Using the future indicative after quando or se is a classic Spanish/Italian transfer error, but it also appears in English-speaker Portuguese:

Forgetting the future-in-the-past conditional is another frequent slip:

Finally, forgetting that atemporal truths stay present produces unintentionally odd sentences:

Key Takeaways

• Present main verb: subordinate tense expresses time directly, no shift.
• Past main verb: subordinate shifts backward — present → imperfect, preterite → pluperfect, future → conditional, present subjunctive → imperfect subjunctive.
• Future main verb: subordinate indicative stays indicative; temporal/conditional conjunctions trigger the future subjunctive.
• Already-past tenses don't re-shift — imperfect, pluperfect, and imperfect subjunctive are terminal.
• Atemporal truths override the backshift — use present indicative regardless of the main clause.
• The conditional is Portuguese's future-in-the-past, not just a hypothetical tense.

The sequence of tenses is where Portuguese grammar rewards precision. Once you stop thinking tense-by-tense and start thinking about the temporal relationship between clauses, the system becomes predictable — and your Portuguese starts sounding noticeably more native.
