This page is the consolidated reference for the congiuntivo — every paradigm, every major trigger, the sequence of tenses, and the modern usage picture in one place. Use it as your one-stop lookup once you have studied the individual subpages. Each section links to the full treatment of that topic.
What the congiuntivo is for
The congiuntivo marks an action or state as subjective — not presented as a fact, but filtered through opinion, emotion, doubt, desire, possibility, or hypothetical reality. It almost always appears in a subordinate clause introduced by che after a main clause that creates this subjective frame.
So che è vero.
I know it's true. (fact → indicativo)
Penso che sia vero.
I think it's true. (opinion → congiuntivo)
The contrast is not about the truth value of "it's true" — it is about how the speaker is presenting the proposition.
The four tenses of the congiuntivo
Italian has four congiuntivo tenses: presente, passato, imperfetto, trapassato. The sequence-of-tenses rules below tell you which to pick.
Congiuntivo presente — regular
| Person | parlare | credere | dormire | finire (-isco) |
|---|---|---|---|---|
| che io | parli | creda | dorma | finisca |
| che tu | parli | creda | dorma | finisca |
| che lui/lei | parli | creda | dorma | finisca |
| che noi | parliamo | crediamo | dormiamo | finiamo |
| che voi | parliate | crediate | dormiate | finiate |
| che loro | parlino | credano | dormano | finiscano |
The three singular forms are identical — Italian almost always uses the subject pronoun (or noun) here to disambiguate. Full treatment: present regular subjunctive.
Congiuntivo presente — high-frequency irregulars
These nine cover roughly 80% of irregular subjunctive usage in real text.
| Infinitive | che io / tu / lui | che noi | che voi | che loro |
|---|---|---|---|---|
| essere | sia | siamo | siate | siano |
| avere | abbia | abbiamo | abbiate | abbiano |
| dare | dia | diamo | diate | diano |
| stare | stia | stiamo | stiate | stiano |
| fare | faccia | facciamo | facciate | facciano |
| potere | possa | possiamo | possiate | possano |
| volere | voglia | vogliamo | vogliate | vogliano |
| sapere | sappia | sappiamo | sappiate | sappiano |
| dire | dica | diciamo | diciate | dicano |
Memorize these now — they appear constantly. Full treatment with more verbs: present irregular subjunctive.
Congiuntivo passato
Formed with avere or essere in the congiuntivo presente + past participle. Used for completed actions in a present-frame context.
Penso che sia già arrivato.
I think he has already arrived.
Mi dispiace che non abbiate potuto venire.
I'm sorry you weren't able to come.
Full treatment: passato del congiuntivo.
Congiuntivo imperfetto — regular
| Person | parlare | credere | dormire |
|---|---|---|---|
| che io | parlassi | credessi | dormissi |
| che tu | parlassi | credessi | dormissi |
| che lui/lei | parlasse | credesse | dormisse |
| che noi | parlassimo | credessimo | dormissimo |
| che voi | parlaste | credeste | dormiste |
| che loro | parlassero | credessero | dormissero |
Used for past-frame contexts and hypothetical "if" clauses (se fossi ricco...). Full treatment: imperfect regular subjunctive.
Congiuntivo trapassato
Formed with avere or essere in the congiuntivo imperfetto + past participle. Used for actions completed before another past action in a subordinate clause.
Pensavo che fosse già arrivato.
I thought he had already arrived.
Full treatment: trapassato del congiuntivo.
The trigger map
The congiuntivo appears after a defined set of triggers. Memorize the categories — once you can classify a main verb or expression by category, you know whether the congiuntivo follows.
| Category | Examples | Required? |
|---|---|---|
| Opinion / belief | penso che, credo che, ritengo che, suppongo che, immagino che | Yes (declining colloquially) |
| Doubt / uncertainty | dubito che, non sono sicuro che, non so se, mi chiedo se | Yes |
| Desire / will | voglio che, desidero che, preferisco che, esigo che, pretendo che | Yes |
| Emotion | sono felice che, mi dispiace che, ho paura che, mi piace che, mi stupisce che | Yes |
| Hope | spero che, mi auguro che | Yes (declining colloquially) |
| Impersonal expressions | è importante che, è meglio che, bisogna che, può darsi che, è strano che | Yes (resistant to decline) |
| Conjunctions of purpose | affinché, perché (= so that), in modo che | Yes |
| Conjunctions of concession | benché, sebbene, nonostante, malgrado | Yes (resistant) |
| Conjunctions of time | prima che, finché (non) — note: dopo che takes indicativo | Yes |
| Conjunctions of condition | a meno che (non), purché, a patto che, qualora | Yes |
| Relatives with indefinite antecedent | cerco qualcuno che..., non c'è nessuno che... | Yes |
| Superlative + che | il libro più bello che abbia mai letto | Yes |

Sequence of tenses
This grid tells you which congiuntivo tense to use based on the main-clause tense and the time relationship.
| Main clause | Subordinate is simultaneous or future | Subordinate is anterior |
|---|---|---|
| Present indicative (penso che...) | Congiuntivo presente (...sia) | Congiuntivo passato (...sia stato) |
| Future (penserò che...) | Congiuntivo presente (...sia) | Congiuntivo passato (...sia stato) |
| Past (imperfetto, passato prossimo, passato remoto) (pensavo che...) | Congiuntivo imperfetto (...fosse) | Congiuntivo trapassato (...fosse stato) |
| Conditional (penserei che...) | Congiuntivo imperfetto (...fosse) | Congiuntivo trapassato (...fosse stato) |
Penso che sia stanca.
I think she's tired. (simultaneous, present main → presente)
Penso che sia stata stanca ieri.
I think she was tired yesterday. (anterior, present main → passato)
Pensavo che fosse stanca.
I thought she was tired. (simultaneous, past main → imperfetto)
Pensavo che fosse stata stanca durante il viaggio.
I thought she had been tired during the trip. (anterior, past main → trapassato)
The same-subject rule
When the subject of the main clause and the subordinate clause are the same, do not use che + congiuntivo. Use di + infinito instead.
Penso di avere ragione.
I think I'm right. (same subject)
Penso che lui abbia ragione.
I think he's right. (different subject)
This is one of the most consistent transfer errors from English, where "I think that I am right" is grammatical. In Italian, the che + congiuntivo construction is reserved for sentences where the two clauses have different subjects.
Standalone uses (without che)
The congiuntivo also appears outside of subordinate clauses in a few important constructions.
Wishes and exhortations (third person imperative)
Che Dio ti benedica.
May God bless you.
Che riposi in pace.
May he rest in peace.
Viva l'Italia!
Long live Italy! (vivere → viva, frozen)
Formal commands (Lei imperative — see also imperative pages)
Si accomodi, prego.
Please make yourself comfortable. (formal: Lei)
Mi dica pure.
Go ahead, tell me. (formal Lei imperative)
Doubt or uncertainty introduced by 'che'
Che sia troppo tardi?
Could it be too late? (rhetorical doubt)
Che abbia dimenticato l'appuntamento?
Could he have forgotten the appointment?
Modern usage: the colloquial picture
In casual spoken Italian, the indicativo increasingly replaces the congiuntivo after high-frequency triggers like penso che, credo che, spero che. Educated, careful, and southern speakers preserve the congiuntivo more reliably; informal northern and central speech routinely uses indicativo. Conjunctions, impersonal expressions, and formal contexts still take the congiuntivo robustly.
For learners: always produce the congiuntivo where the rule requires it (it is never wrong in any register), but expect to hear the indicativo in spontaneous conversation. See the decline of congiuntivo in colloquial Italian for the full discussion.
Common mistakes
❌ Penso che lui parla bene italiano.
Incorrect for standard register — should be congiuntivo: parli.
✅ Penso che lui parli bene italiano.
Correct — penso che + congiuntivo.
❌ Penso che io ho ragione.
Incorrect — same subject requires infinitive, not che + finite verb.
✅ Penso di avere ragione.
Correct — same subject takes di + infinito.
❌ Pensavo che è stanca.
Incorrect tense sequence — past main clause requires imperfect or trapassato congiuntivo.
✅ Pensavo che fosse stanca.
Correct — pensavo (past) + fosse (imperfetto).
❌ Spero che sia venuto domani.
Incorrect — congiuntivo passato is for actions already completed, not for future ones. Use congiuntivo presente.
✅ Spero che venga domani.
Correct — future-leaning meaning takes congiuntivo presente.
❌ Benché è tardi, esco.
Incorrect — benché requires congiuntivo without exception, even in casual speech.
✅ Benché sia tardi, esco.
Correct.

The congiuntivo is one of the most rewarding parts of Italian grammar to internalize: once the logic clicks, half a dozen seemingly disconnected constructions snap into a single system.
