Italian Third Conditional: Talking About Unreal Past Situations
Learn to form and use the Italian third conditional (periodo ipotetico del terzo tipo) to express hypothetical situations in the past, like 'Se avessi saputo, avrei chiamato.'
By TheaFirst conversations · Yapr Learn
The Italian third conditional lets you talk about past situations that did not happen and their imagined consequences. In English you say 'If I had known, I would have called.' In Italian, this structure uses the congiuntivo trapassato (past perfect subjunctive) after 'se' and the condizionale passato (past conditional) in the main clause. This lesson teaches you to build these sentences accurately, distinguish them from the second conditional, and use them naturally in conversation.
By the end, you can…
- form the third conditional in Italian using 'se' + congiuntivo trapassato and condizionale passato.
- distinguish between the second conditional (unreal present) and the third conditional (unreal past) in Italian.
- talk about regrets and missed opportunities in Italian using the third conditional.
Listen once. Try it slowly. Then say it without looking.

Se avessi saputo, avrei chiamato.
If I had known, I would have called.
seh ah-VES-see sah-POO-toh, ah-VREH-ee kyah-MAH-toh
Classic third conditional example. 'Avessi' is congiuntivo trapassato of 'avere'; 'avrei chiamato' is condizionale passato.
Se fossi partito prima, non avrei perso il treno.
If I had left earlier, I would not have missed the train.
seh FOS-see par-TEE-toh PREE-mah, non ah-VREH-ee PEHR-soh eel TREH-noh
Uses 'fossi' (congiuntivo trapassato of 'essere') and 'avrei perso' (condizionale passato). Note the past participle agreement with 'partito'.
Se avessimo studiato di più, avremmo superato l'esame.
If we had studied more, we would have passed the exam.
seh ah-VES-see-moh stoo-DYAH-toh dee PEW, ah-VREM-moh soo-peh-RAH-toh leh-ZAH-meh
First-person plural forms: 'avessimo' and 'avremmo'. Common in academic or professional contexts.
Se non fosse stato per te, non ce l'avrei fatta.
If it hadn't been for you, I wouldn't have made it.
seh non FOS-seh STAH-toh per teh, non cheh lah-VREH-ee FAHT-tah
Idiomatic expression. 'Fosse stato' is congiuntivo trapassato; 'ce l'avrei fatta' is a pronominal verb in condizionale passato.
Cosa avresti fatto al mio posto?
What would you have done in my place?
KOH-zah ah-VRES-tee FAHT-toh ahl MEE-oh POH-stoh
Useful question to elicit third conditional responses. 'Al mio posto' means 'in my position'.

Useful pattern
The Italian third conditional follows a fixed pattern: 'Se' + congiuntivo trapassato (past perfect subjunctive), then condizionale passato (past conditional) in the main clause. For example: 'Se avessi mangiato, non avrei avuto fame' (If I had eaten, I wouldn't have been hungry). The congiuntivo trapassato is formed with 'avessi' or 'fossi' plus the past participle: 'avessi parlato', 'fossi andato/a'. The condizionale passato uses 'avrei' or 'sarei' plus the past participle: 'avrei parlato', 'sarei andato/a'. Remember that 'essere' verbs require agreement of the past participle with the subject: 'sarei andata' (feminine), 'saremmo partiti' (masculine plural).
When to use it
Use the third conditional to talk about hypothetical past events that did not occur, often expressing regret, criticism, or relief. For example: 'Se avessi preso l'altra strada, non avrei incontrato Marco' (If I had taken the other road, I wouldn't have met Marco). It contrasts with the second conditional, which describes unreal present or future situations: 'Se avessi una macchina, andrei al lavoro in auto' (If I had a car, I would drive to work). The third conditional is fixed on the past and cannot be used for present hypotheses. In informal speech, some speakers in Tuscany and parts of central Italy may use the passato prossimo instead of the congiuntivo trapassato ('Se avevo saputo...'), but this is non-standard and should be avoided in formal writing.
Listen to each line, then take one part and reply out loud.
Se avessi saputo che c'era sciopero, avrei preso il taxi.
If I had known there was a strike, I would have taken a taxi.seh ah-VES-see sah-POO-toh keh CHEH-rah SHOH-peh-roh, ah-VREH-ee PREH-zoh eel TAHK-seeAnch'io! Se non avessi aspettato te, sarei arrivato in orario.
Me too! If I hadn't waited for you, I would have arrived on time.ahn-KYOH! seh non ah-VES-see ahs-peht-TAH-toh teh, sah-REH-ee ar-ree-VAH-toh een oh-RAH-ryohScusa! Se avessi controllato gli orari, avremmo evitato il ritardo.
Sorry! If I had checked the schedules, we would have avoided the delay.SKOO-zah! seh ah-VES-see kohn-trohl-LAH-toh lyee oh-RAH-ree, ah-VREM-moh eh-vee-TAH-toh eel ree-TAR-dohNon importa. Se avessimo preso la metro, non avremmo perso tempo.
It doesn't matter. If we had taken the subway, we wouldn't have wasted time.non eem-POR-tah. seh ah-VES-see-moh PREH-zoh lah MEH-troh, non ah-VREM-moh PEHR-soh TEM-pohA little context goes a long way
In standard Italian, the third conditional is used across all regions, but in informal spoken language in Tuscany and parts of central Italy, you may hear 'Se avevo saputo, ti chiamavo' instead of the standard 'Se avessi saputo, ti avrei chiamato'. This substitution is regional and colloquial; learners should master the standard form for formal writing and professional contexts.
One thing to watch for
Using the passato prossimo or imperfetto after 'se' in a third conditional, as in 'Se avevo saputo, avrei chiamato.'
Try this instead: Always use the congiuntivo trapassato after 'se' in standard Italian: 'Se avessi saputo, avrei chiamato.' The passato prossimo ('avevo saputo') is non-standard here. Similarly, avoid using the condizionale passato after 'se': 'Se avrei saputo' is wrong; use 'Se avessi saputo'.
Your turn
Try answering out loud before checking a possible answer.
1Translate: 'If they had arrived earlier, they would have seen the show.'
Show a sample answer
Se fossero arrivati prima, avrebbero visto lo spettacolo.
'Fossero arrivati' is congiuntivo trapassato of 'arrivare' (with 'essere'), and 'avrebbero visto' is condizionale passato. The past participle 'arrivati' agrees with the masculine plural subject.
2Which is correct: 'Se avrei tempo, verrei' or 'Se avessi tempo, verrei'? Explain.
Show a sample answer
'Se avessi tempo, verrei' is correct.
This is a second conditional (unreal present). After 'se', use the congiuntivo imperfetto ('avessi'), not the condizionale ('avrei'). The main clause uses condizionale presente ('verrei').
3Complete: 'Se ___ (noi) ___ (partire) prima, non ___ (perdere) il volo.'
Show a sample answer
Se fossimo partiti prima, non avremmo perso il volo.
'Fossimo partiti' is congiuntivo trapassato of 'partire' (with 'essere'), and 'avremmo perso' is condizionale passato of 'perdere'. The participle 'partiti' agrees with 'noi' (masculine plural).
Master the third conditional by memorizing the pattern: 'Se' + congiuntivo trapassato, then condizionale passato. Use it for unreal past situations, regrets, and missed opportunities. Avoid using passato prossimo or condizionale after 'se' in standard Italian.
