Italian Subjunctive Explained: Complete Guide with Examples
Introduction: What Is the Italian Subjunctive?
The Italian subjunctive (il congiuntivo) is a verb mood that expresses doubt, uncertainty, desire, emotion, or hypothetical situations. Unlike the indicative mood, which states facts, the subjunctive deals with the realm of possibility and subjectivity. Understanding the Italian subjunctive explained in practical terms is essential for anyone wanting to speak Italian fluently and naturally.
The subjunctive appears far more frequently in Italian than in English, where it has largely disappeared from everyday speech. In Italian, you'll encounter it constantly in subordinate clauses introduced by the conjunction che (that), as well as in certain independent expressions.
There are four subjunctive tenses in Italian:
- Present subjunctive (congiuntivo presente) – for present or future actions
- Past subjunctive (congiuntivo passato) – for completed actions
- Imperfect subjunctive (congiuntivo imperfetto) – for past hypothetical or contrary-to-fact situations
- Past perfect subjunctive (congiuntivo trapassato) – for actions completed before another past action
Formation: Italian Subjunctive Conjugation
Learning the Italian subjunctive conjugation requires memorizing specific endings for each verb group. The good news is that the patterns are consistent once you learn them.
Present Subjunctive (Congiuntivo Presente)
To form the present subjunctive, drop the infinitive ending and add the subjunctive endings. Note that -ARE verbs take -E/-I endings while -ERE and -IRE verbs take -A/-I endings—the opposite of the indicative!
| Person | -ARE (parlare) | -ERE (scrivere) | -IRE (dormire) | -IRE -isc (capire) |
|---|---|---|---|---|
| io | parli | scriva | dorma | capisca |
| tu | parli | scriva | dorma | capisca |
| lui/lei | parli | scriva | dorma | capisca |
| noi | parliamo | scriviamo | dormiamo | capiamo |
| voi | parliate | scriviate | dormiate | capiate |
| loro | parlino | scrivano | dormano | capiscano |
Key Irregular Verbs in Present Subjunctive
Several common verbs have irregular subjunctive forms that must be memorized:
| Person | essere | avere | andare | fare | stare |
|---|---|---|---|---|---|
| io | sia | abbia | vada | faccia | stia |
| tu | sia | abbia | vada | faccia | stia |
| lui/lei | sia | abbia | vada | faccia | stia |
| noi | siamo | abbiamo | andiamo | facciamo | stiamo |
| voi | siate | abbiate | andiate | facciate | stiate |
| loro | siano | abbiano | vadano | facciano | stiano |
Imperfect Subjunctive (Congiuntivo Imperfetto)
The imperfect subjunctive is formed by adding specific endings to the verb stem:
| Person | -ARE (parlare) | -ERE (scrivere) | -IRE (dormire) |
|---|---|---|---|
| io | parlassi | scrivessi | dormissi |
| tu | parlassi | scrivessi | dormissi |
| lui/lei | parlasse | scrivesse | dormisse |
| noi | parlassimo | scrivessimo | dormissimo |
| voi | parlaste | scriveste | dormiste |
| loro | parlassero | scrivessero | dormissero |
Compound Subjunctive Tenses
The past subjunctive and past perfect subjunctive are compound tenses formed with the subjunctive of avere or essere plus the past participle:
- Past subjunctive: present subjunctive of avere/essere + past participle
(che io abbia parlato, che tu sia andato) - Past perfect subjunctive: imperfect subjunctive of avere/essere + past participle
(che io avessi parlato, che tu fossi andato)
Usage: How to Use Subjunctive in Italian
Knowing how to use subjunctive in Italian correctly requires understanding the contexts that trigger it. The subjunctive typically appears in dependent clauses after certain verbs, conjunctions, and expressions.
After Verbs of Opinion, Doubt, and Uncertainty
Verbs that express belief, doubt, or uncertainty trigger the subjunctive in the following clause:
- pensare che (to think that)
- credere che (to believe that)
- dubitare che (to doubt that)
- sembrare che (to seem that)
- non essere sicuro che (to not be sure that)
After Verbs of Desire, Will, and Preference
When expressing what you want, hope, or prefer someone else to do:
- volere che (to want that)
- sperare che (to hope that)
- preferire che (to prefer that)
- desiderare che (to desire that)
After Verbs of Emotion
Feelings and emotional reactions require the subjunctive:
- essere felice che (to be happy that)
- avere paura che (to be afraid that)
- dispiacere che (to be sorry that)
- sorprendersi che (to be surprised that)
After Impersonal Expressions
Many impersonal constructions trigger the subjunctive:
- è importante che (it's important that)
- è necessario che (it's necessary that)
- è possibile che (it's possible that)
- bisogna che (it's necessary that)
- è meglio che (it's better that)
After Certain Conjunctions
Some conjunctions always require the subjunctive:
- benché / sebbene (although)
- affinché / perché (so that, in order that)
- prima che (before)
- a meno che non (unless)
- senza che (without)
- purché (provided that)
In Conditional Sentences
The imperfect subjunctive is used in hypothetical "if" clauses:
- Possible condition: Se avessi tempo, verrei. (If I had time, I would come.)
- Impossible past condition: Se fossi venuto, ti avrei visto. (If I had come, I would have seen you.)
Examples: Italian Subjunctive Examples in Context
Here are practical Italian subjunctive examples that demonstrate how native speakers use this mood in everyday conversation:

Se fossi ricco, viaggerei per il mondo.
If I were rich, I would travel the world.
Non credo che lui abbia capito la domanda.

Prima che tu parta, devo dirti una cosa.
Before you leave, I have to tell you something.

Common Mistakes When Learning Italian Subjunctive
As you learn Italian subjunctive, be aware of these frequent errors that learners make:
1. Using Indicative Instead of Subjunctive
Many learners default to the indicative when the subjunctive is required, especially with verbs of opinion:
- ❌ Penso che Marco è simpatico.
- ✓ Penso che Marco sia simpatico.
2. Forgetting the Subjunctive After Conjunctions
Certain conjunctions always require the subjunctive, but learners often forget:
- ❌ Benché piove, esco.
- ✓ Benché piova, esco.
3. Confusing the -ARE and -ERE/-IRE Endings
Remember that -ARE verbs use -I endings in the subjunctive while -ERE/-IRE verbs use -A endings—the opposite of the indicative:
- ❌ Voglio che lui parla.
- ✓ Voglio che lui parli.
4. Wrong Tense Sequence (Consecutio Temporum)
Italian has strict rules about which subjunctive tense follows which main clause tense:
- Present/future main verb → present or past subjunctive
- Past main verb → imperfect or past perfect subjunctive
Example:
- ❌ Pensavo che Maria sia malata.
- ✓ Pensavo che Maria fosse malata.
5. Using Subjunctive When Not Required
Not all che clauses require the subjunctive. Factual statements use the indicative:
- ✓ So che Marco è italiano. (I know Marco is Italian – this is a fact)
- ✓ Penso che Marco sia italiano. (I think Marco is Italian – this is an opinion)
6. Omitting the Subject Pronoun When Needed
Since io, tu, and lui/lei have the same form in the present subjunctive, context or an explicit subject pronoun may be necessary to avoid ambiguity:
- Penso che tu abbia ragione. (I think you are right.)
With consistent practice and attention to the triggers that require it, the Italian subjunctive will become a natural part of your speech. Focus on learning the most common irregular verbs first (essere, avere, fare, andare, stare), and pay attention to the subjunctive in Italian media you consume.
