Sequence of Tenses (Concordanza dei Tempi)

The single most frequent advanced subjunctive error Italian learners make is choosing the wrong tense of the congiuntivo — not the wrong mood. The grammar that governs which tense to use is called la concordanza dei tempi (literally, "agreement of tenses"), and it can be reduced to a single insight: the tense of the main verb determines which tenses are available in the subordinate clause. Master the four cells of the sequence-of-tenses grid and your B2-level Italian will jump in accuracy overnight.

The two questions

Every time you build a che + congiuntivo clause, ask yourself two questions:

1. Is the main verb in a present/future block, or in a past/conditional block?
2. Is the subordinate action simultaneous-or-future relative to the main verb, or anterior to it (i.e., already over before the main verb's time)?

The answers map you to one of four cells:

This table is the entire system. The rest of this page is just learning to read it fluently.

Block 1 — main verb in present or future

When the main verb is in presente, futuro, passato prossimo with present relevance, or imperativo, the subordinate clause uses one of the two short-form tenses: presente congiuntivo or passato congiuntivo.

Simultaneous or future → presente congiuntivo

If the action of the subordinate clause happens at the same time as, or after, the main verb's action, use the presente congiuntivo.

Italian does not have a distinct future subjunctive in everyday use — the presente congiuntivo covers both now and later.

Anterior → passato congiuntivo

If the subordinate action precedes the time of the main verb — already done by the time the main verb is being said — use the passato congiuntivo (sia / abbia + past participle).

Block 2 — main verb in past or conditional

When the main verb is in imperfetto, passato remoto, trapassato, condizionale presente, or condizionale passato, the subordinate clause uses one of the two long-form tenses: imperfetto congiuntivo or trapassato congiuntivo.

Simultaneous or future-in-the-past → imperfetto congiuntivo

If the subordinate action happens at the same time as the past main verb, or after it (but still in the past from today's vantage), use the imperfetto congiuntivo.

The shift from viene → venisse, non piova → non piovesse, dica → dicessi is just the imperfetto congiuntivo applying to the same content one tense level back. Once Block 2 is triggered by the past-tense main verb, the whole subordinate clause moves with it.

Anterior to the past main verb → trapassato congiuntivo

If the subordinate action happened before the time of the past main verb — i.e., past from a vantage point that is itself in the past — use the trapassato congiuntivo (fossi / avessi + past participle).

The trapassato congiuntivo is the past-of-a-past in subjunctive form. Use it whenever you would have used the trapassato prossimo in an indicative version of the same sentence.

The four cells side by side

The same content, Marco comes to the party, mapped to all four cells:

If you can fluently produce all four versions of I think(thought) Marco is(was)/has(had) come to the party, you have the sequence of tenses.

What counts as "main verb in past"

Block 2 is triggered not only by the imperfetto and passato remoto, but also by:

• Passato prossimo when it has clear past reference: Ho pensato che fossi a casa — past frame, so imperfetto congiuntivo follows.
• Condizionale presente: Vorrei che tu venissi (I would like you to come). The condizionale, even though it points to a hypothetical present/future, takes Block 2 in standard Italian.
• Condizionale passato: Avrei voluto che tu fossi venuto (I would have liked you to have come). Triggers Block 2 with full force.

The condizionale's behavior is the source of countless errors. Vorrei che tu venga — combining condizionale with presente congiuntivo — is widely heard in spoken Italian and accepted in informal speech, but in careful and written Italian, the standard form is vorrei che tu venissi.

Passato prossimo: a borderline case

The passato prossimo straddles the two blocks depending on whether you treat it as connected to the present (recent action with present consequences) or as a standalone past event. Both options are used:

There is no error in either; the choice tracks the speaker's framing of the main verb. As a rule of thumb, if you can replace the passato prossimo with a presente without changing the meaning, treat it as Block 1. If you cannot, treat it as Block 2.

Future and imperative as Block 1

Both the futuro semplice and the imperativo belong to Block 1 — they pull the subordinate clause into the present-time orbit:

The intuition: if the main verb sits at or after the moment of speaking, Block 1 applies.

A diagnostic checklist

When you build a congiuntivo clause, run through this in order:

1. What is the tense of the main verb? Present / future / imperative / present-relevance passato prossimo? → Block 1. Imperfetto / passato remoto / condizionale / past-event passato prossimo / trapassato? → Block 2.
2. Is the subordinate action happening at the same time as the main verb, or later? → left column (presente / imperfetto).
3. Or did the subordinate action happen before the main verb? → right column (passato / trapassato).
4. Pick the cell. Conjugate the verb in that cell.

The system gives you exactly one correct form per choice.

Common mistakes

Key takeaways

The concordanza dei tempi is a four-cell grid:

1. Main = present/future block + simultaneous/future subordinate → presente congiuntivo.
2. Main = present/future block + anterior subordinate → passato congiuntivo.
3. Main = past/conditional block + simultaneous/future-in-past subordinate → imperfetto congiuntivo.
4. Main = past/conditional block + anterior subordinate → trapassato congiuntivo.

Two blocks, two time relations, four cells. Internalize the grid and the wrong-tense errors that plague intermediate learners disappear.
