The imperfect and past perfect subjunctive: How to form and use them in Italian?

By: Silvia Giorgini Althoen

In Italian, the subjunctive mood helps us express our inner thoughts and emotions. The imperfect subjunctive (congiuntivo imperfetto) and past perfect subjunctive (congiuntivo trapassato) are two of the four tenses we can use in this mood (the other two being present and past). We classically use these tenses when the main situation we’re talking about is in the past, for example:

  • imperfect subjunctive
    Ho pensato che venisse.
    Translation: I thought that s/he would come.
    The thinking happened in the past.
  • past perfect subjunctive
    Sembrava che fossero tornati.
    Translation: It looked like they had returned.
    It looked that way in the past.

However, there are a few other cases where you’ll use the imperfect or past perfect subjunctive as well! Now, leave the present behind, and enter the realm of possibilities, wishes, and feelings in the past. Ready to dive into this world? Let’s go!

How to form the imperfect subjunctive in Italian?

The imperfect subjunctive in Italian is formed by dropping the infinitive endings and adding the appropriate imperfect subjunctive endings. As always, regular and irregular verbs will be a little different, but we have some cool tricks in store for you!

Regular verbs

To form the imperfect subjunctive of regular verbs, we need to start by identifying the three main verb groups. Let’s tickle our memory and refresh the Italian “verb trilogy.” In Italian the three main verb groups are those ending in -are, -ere, and -ire.

When conjugating you would normally drop the full infinitive ending (-are, -ere, -ire) and then add the tense endings. However, check out this trick my students use to form the imperfetto congiuntivo, by just dropping -re!

Subject Pronoun-are-ere-ire

io meaning I

parl-assi
av-essi
apr-issi

tu meaning you

parl-assi
av-essi
apr-issi

lei/lui meaning s/he

parl-asse
av-esse
apr-isse

noi meaning we

parl-assimo
av-essimo
apr-issimo

voi meaning you all

parl-aste
av-este
apr-iste

loro meaning they

parl-assero
av-essero
apr-issero

Do you see the pattern?

  1. Leave the first vowel of the infinitive ending (a, e, i) on the stem!

  2. All three conjugations use the same imperfect subjunctive endings: -ssi, -sse, -ssimo, -ste, -ssero.

  3. The io meaning I and tu meaning you forms will have the same ending: -ssi, so remember to always indicate the subject to avoid confusion:

    Pensavano che tu arrivassi domani.
    Translation: They thought that you would arrive tomorrow.
    Speravate che io arrivassi domani.
    Translation: You hoped that I would arrive tomorrow.

Irregular verbs

Irregular verbs in the imperfect subjunctive also have the same endings as above – they just have an irregular stem which you have to memorize. Ready for more good news? Most of the verbs are regular in the imperfetto congiuntivo, so learn the most common five by heart, and check the link for a handy printable with irregular verbs in the imperfect subjunctive for the rest!

How to form the past perfect subjunctive in Italian?

The past perfect subjunctive, or trapassato congiuntivo, is a compound tense, which means that once you know the imperfect subjunctive of avere meaning to have and essere meaning to be you just add the past participle and you have it!

avere meaning to have / essere meaning to be

past participle

Non sapeva che voi aveste comprato casa.
Translation: He didn’t know you had bought a house.
Pensavo che Giulia si fosse laureata.
Translation: I thought Giulia graduated.

When to use the imperfect or past perfect subjunctive in Italian?

The imperfect and past perfect subjunctive follow the same “triggers” as the subjunctive in any tense, but which one you use will most often depend on when the various actions happen.

You can read all about these “subjunctive triggers” in our post on how to use the Italian subjunctive, but here are the two main points, to refresh your memory!

  • The subjunctive is mostly used in subordinate clauses, introduced by the word che meaning that when the subjects of the two clauses are different:

    Credevo che Mario amasse questa città.
    Translation: I believed that Mario loved this city.
  • Additionally the main clause must have something in it that “triggers” the subjunctive.

    • Usually, these are expressions that indicate the following clause is something that is a thought, plan, opinion, or feeling, inside someone’s head, for example:

      • dubitare che... meaning to doubt that...

      • pensare che... meaning to think that...

      • è importante che… meaning it's important that...

    • Sometimes the “trigger” is a conjunction like benché/sebbene meaning althoughor an indefinite expression like chiunque meaning whoever instead.

So the imperfect and past perfect subjunctive follow the same triggers as the subjunctive in any tense. How will you know which one to use? By looking at when the different actions are taking place. Let’s have a look!

When to use the imperfect subjunctive in Italian?

Here are the main cases where you can use the imperfect subjunctive in Italian:

  • When the verb in the main clause is past tense and the subjunctive action happens at about the same time:

    imperfect subjunctive
    Ho pensato che arrivassero insieme.
    Translation: I thought they would arrive together.
    I pictured that the thinking and the arriving happening at about the same time.

    Here are some examples with other sorts of subjunctive triggers. Notice that the main clause is always in the past tense:

    essere + adjective

    Era importante che parlassimo.
    Translation: It was important that we talked.

    an impersonal expression

    Sembrava che piovesse.
    Translation: It looked like it would rain.

    a conjunction

    Abbiamo fatto il possibile, affinché andasse in Italia.
    Translation: We did all we could so that s/he could go to Italy.

    an indefinite expression

    Gli dicevano sempre di sì, qualunque cosa dicesse.
    Translation: They always said yes, no matter what s/he said.
  • When the main clause is in the present conditional:

    present conditionalimperfect subjunctive
    Vorrei che leggesse questo libro.
    Translation: I wish s/he would read this book.
    Literally: I want that s/he read this book.

    When paired with the present conditional, the imperfetto congiuntivo can refer to an action in the present or the future, but there are some special cases.

    We form sentences that explain what would happen if something else happened (also known as type 2 hypotheticals) like this:

    se meaning if

    imperfect subjunctive

    present conditional

    Se tu finissi il tuo saggio entro la prossima settimana, saremmo contenti.
    Translation: If you finish your essay by next week, we will be happy.
  • with come se meaning as if:

    When a subordinate clause is introduced by come se we use the imperfect subjunctive to advance a hypothesis that may or may not be true about the action in the main clause.

    • Parla come se io non fossi qui.
      Translation: She talks as if I weren’t here.
    • È rimasto in silenzio, come se avesse paura di parlare.
      Translation: He remained silent, as if he were afraid of talking.
    • Se ne andranno da qui, come se niente fosse.
      Translation: They will leave here, as if nothing happened.

    Notice that the main clause can be in any tense (present, passato prossimo, imperfect, or future)!

  • with magari meaning if only to express a wish/desire in the present:

    Magari telefonasse di più!
    Translation: If only s/he called more often!

When to use the past perfect subjunctive in Italian?

The past perfect subjunctive uses are mostly the same as for the imperfect subjunctive, (same “triggers”), but in this case the action in the second clause has happened before the one in the main clause.

  • When the verb in the main clause is past tense, but the subjunctive action ought to have happened earlier:

    past perfect subjunctive
    Sembrava che avessero capito.
    Translation: It looked like they had understood.
    It looked like they understood it before some past moment.
  • When the present conditional OR past conditional is in the main clause, and the subjunctive action ought to have happened before:

    • present conditionalpast perfect subjunctive
      Vorrei che avessero letto questo libro.
      Translation: I would like them to have read this book.
      I want the reading to be finished before now.
    • past conditionalpast perfect subjunctive
      Avrei voluto che avessero letto questo libro.
      Translation: I would have liked them to have read this book.
      I want the reading to be finished before some past moment.
  • To talk about impossible hypotheticals that say what would have happened if something else had taken place (a.k.a. Type 3 Hypotheticals):

    se meaning if

    past perfect subjunctive

    past conditional

    Se tu fossi venuta per le feste, saremmo stati contenti.
    Translation: If you had come for the holidays, we would have been happy.
  • with magari meaning if only to express a wish/desire in the past:

    Magari tu avessi chiamato prima di venire!
    Translation: If only you had called before coming!

Summing Up

The subjunctive imperfetto and trapassato are used much like the other subjunctive tenses. Just remember that:

  • It’s mostly used in subordinate clauses, and its use depends on what is in the main clause and if the main verb is in the past or the present or past conditional:

    • Is it a D.O.V.E. verb?

    • Is it an impersonal expression?

    • Is it essere + adjective?

    • Is it an indefinite expression?

    • Is there a conjunction like benché/sebbene? (imperfect/past perfect subjunctive)

  • OR:

    • Is it introduced by magari → imperfect/past perfect

    • Do you have an “if clause”?

      • SE + imperfect subjunctive + conditional present OR

      • SE + past perfect subjunctive + conditional past
