ITALIAN CONDITIONS (TYPE 3)
The terzo periodo ipotetico (third conditional) in Italian is used to talk about hypothetical situations in the past—things that could have happened but didn’t.
This structure is essential for expressing regret, missed opportunities, or alternative outcomes that were not realised.

BASIC STRUCTURE
The verb in the if-clause is in the congiuntivo trapassato (past perfect subjunctive), while the verb in the main clause is in the condizionale passato (past conditional).
PATTERN
Se + past perfect subjunctive + past conditional
This formation expresses hypothetical situations that did not happen in the past, making it similar to the English “If I had studied, I would have passed.”
WHEN TO USE THE THIRD CONDITIONAL
The third conditional is used when:
- You imagine a different past: Expressing how things could have been different.
- You express regret: Talking about missed opportunities.
- You describe hypothetical alternative past outcomes: Discussing what would have happened under different conditions.
ANALYSING THE STRUCTURE
The Congiuntivo Trapassato (Past Perfect Subjunctive)
The congiuntivo trapassato is formed with the imperfetto del congiuntivo of essere or avere plus the past participle.
verb | Avere (to have) | Essere (to be) |
---|---|---|
Io | avessi avuto | fossi stato/a |
Tu | avessi avuto | fossi stato/a |
Lui/Lei | avesse avuto | fosse stato/a |
Noi | avessimo avuto | fossimo stati/e |
Voi | aveste avuto | foste stati/e |
Loro | avessero avuto | fossero stati/e |
For example:
- Mangiare (to eat) → Se io avessi mangiato…
- Partire (to leave) → Se tu fossi partito…
The Condizionale Passato (Past Conditional)
The condizionale passato is formed with the condizionale presente of essere or avere plus the past participle.
Verb | Avere (to have) | Essere (to be) |
---|---|---|
Io | avrei avuto | sarei stato/a |
Tu | avresti avuto | saresti stato/a |
Lui/Lei | avrebbe avuto | sarebbe stato/a |
Noi | avremmo avuto | saremmo stati/e |
Voi | avreste avuto | sareste stati/e |
Loro | avrebbero avuto | sarebbero stati/e |
For example:
- Mangiare (to eat) → Avrei mangiato…
- Partire (to leave) → Sarei partito/a…
