Have you ever heard Italians say things like “Si mangia bene qui” (You eat well here) or “Si dice che sia vero” (They say it’s true) and wondered who they are talking about? This is the so-called SI impersonale—a clever way to talk about general ideas or habits without naming anyone specifically.
In this guide, you’ll learn, step-by-step, the structure of the SI impersonale, when and why Italians use it in everyday conversations and how to use it confidently with reflexive verbs, modal verbs, and more. We’ll also compare the differences between SI impersonale and SI passivante (hint: it’s subtler than you think).
Here’s the kicker: did you know there’s a tiny change in the rule when SI impersonale meets reflexive verbs? Stay with me to uncover this trick—it’s a game-changer for fluency in Italian!

What is the SI impersonale in Italian?
The SI impersonale is one of the many uses of the pronoun si in Italian. It’s a grammatical construction that’s incredibly common in everyday conversation to express universal truths, habits, or situations in a general way, without referring to a specific subject. In English, it often translates to expressions like “they say,” “you can,” or “one does.”
The word impersonale perfectly reflects its meaning. It comes from the Latin term impersonalis, which literally translates to “not personal.”
Let’s look at these two sentences:
- Mike parla italiano — Mike speaks Italian → Here, Mike is the clear subject.
- In Italia si parla italiano — In Italy people speak Italian → In this case, there is no specific subject and si translates to something like “people” or “everyone” in a general sense.
3 Key characteristics of the SI impersonale
The SI impersonale in Italian is characterized by three main elements:
1. The generic subject
Although si looks like a reflexive pronoun, it actually serves a different function in this construction. Unlike the reflexive si, which refers to a specific subject (like “himself” or “herself”), the SI impersonale acts as an indefinite subject, equivalent to words like tutti (everybody), la gente (people), le persone (people), etc. For example:
- Si vive meglio al mare — One lives better by the sea
- Si dorme meglio quando fa più fresco — One sleeps better when it’s cooler
2. The verb in the third-person singular
Verbs that follow the SI impersonale are always conjugated at the third-person singular and can be either:
- Intransitive verbs, which don’t take a direct object, for example: Con la macchina si arriva più velocemente (By car, one arrives more quickly)
- Transitive verbs, which typically take a direct object. However, in the SI impersonale construction, the direct object is not present, for example: In questa trattoria si mangia bene (In this trattoria, people eat well)
3. The flexibility
Finally, the SI impersonale construction can be used with all tenses (present, imperfetto, passato remoto, etc.) and moods (indicative, subjunctive, conditional, etc.), making it adaptable to various contexts.
How to form the SI impersonale
Building sentences with the SI impersonale in Italian is quite simple. Here are the key rules to follow:
SI impersonale with simple tenses
For simple tenses, which are formed with just one word (like the present, imperfect, passato remoto, or future), the structure is straightforward:
SI + verb in third-person singular
Examples:
- A Natale si mangia il panettone in Italia — At Christmas, people eat panettone in Italy
- La domenica si mangia tutti insieme — On Sundays, people eat together
SI impersonale with compound tenses
Compound tenses, which are formed with more than one word (like the passato prossimo or the future perfect), the SI impersonale requires the auxiliary verb essere (to be) and follows this construction:
SI + “essere” in third-person singular + past participle
The past participle changes based on the verb:
- Verbs that require the auxiliary avere (to have) in the personal form use the masculine singular form of the past participle with the SI impersonale:
- L’estate scorsa si è viaggiato tanto — Last summer, people traveled a lot
- Alla festa di Carla si è mangiato davvero tanto — At Carla’s party, people ate a lot
- Verbs that require the auxiliary essere (to be) in the personal form use the plural masculine form of the past participle with the SI impersonale:
- Ieri sera si è stati fuori fino a tardi a festeggiare — Last night, people were out celebrating until late
- Si è partiti presto per evitare il traffico — People left early to avoid the traffic
SI impersonale with reflexive verbs
In Italian, reflexive verbs already include the reflexive pronoun SI in their structure. When used in the impersonal form, the SI impersonale changes to CI to avoid the repetition of SI twice in the sentence. So, the structure becomes:
CI + reflexive SI + verb in third-person singular
For instance:
- In Italia a Capodanno si si veste di rosso → In Italia a Capodanno ci si veste di rosso (In Italy, on New Year’s Eve, people dress in red)
- Con quella guida si si diverte sempre → Con quella guida ci si diverte sempre (With that guide, people always have fun)
In compound tenses, the auxiliary verb remains essere (to be), and the past participle usually takes the masculine plural form:
- Ci si è vestiti di fretta e furia per non fare tardi — People got dressed quickly in a rush so as not to be late
- Non ci si è chiesti cosa sarebbe successo — No one asked what would have happened
SI impersoale with modal verbs
Modal verbs take the third-person singular form and are followed by a verb in the infinitive form:
SI + modal verb in third-person singular + verb in infinitive form
For example:
- Si deve provare sempre! — One must always try!
- Si vuole giocare domani — They want to play tomorrow
- Non si può fumare qui — Smoking is not allowed here
When using this construction with compound tenses, the modal verb is conjugated in the past participle singular masculine:
SI + “essere” in third-person singular + past participle of the modal verb + verb in infinitive form
For example:
- Durante la visita non si è potuto telefonare — During the visit, people couldn’t make phone calls
- Si è dovuto attendere fuori al freddo — One had to wait outside in the cold
- Si è voluto fare così — They wanted to do things this way
SI impersonale with pronouns
When using the SI impersonale with pronouns, the word order can seem tricky at first. But don’t worry, once you learn the two basic rules below, it becomes quite easy to master:
- The SI impersonale always goes right before the verb
- Other pronouns are placed before the SI
Some examples:
- Le si è detto di aspettare — She was told to wait
- Non mi si deve scrivere qui — People shouldn’t write me here
- Anche se ci si è stati di recente, ogni volta è come la prima — Even if one has been there recently, every time is like the first
With pronominal verbs that contain the pronoun ne, the SI impersonale changes to se and always goes before ne:
- Non se ne parla! — It’s not up for discussion!
- Non se ne viene a capo — No one can come to a conclusion
- Quando ci si arrabbia, se ne dicono di tutti i colori — When people get angry, they say all sorts of things
In more complex sentences where the SI impersonale combines with two or more pronouns, the word order follows this pattern:
Indirect or reflexive pronoun (changing the ending to -e) + direct object pronoun + SI impersonale
For example:
- Ve lo si legge in faccia — It’s clear from your faces
- Te lo si dice sempre — People always tell you that
SI impersonale with adjectives
When the SI impersonale construction is followed by an adjective, the adjective must be in the plural masculine form, even though the verb remains in the third person singular. For example:
- Si è stanchi dopo una giornata per musei — One is tired after a day at museums
- Quando si è curiosi, si impara sempre qualcosa di nuovo — When one is curious, they always learn something new
If you’re talking about women in general, then the adjective can be in the plural feminine form:
- Si è stufe di non essere ascoltate — Women are tired of not being listened to
- Si è deluse per le risposte — Women are disappointed by the responses
6 Common uses of the SI impersonale in Italian
Here are the most common scenarios where you’ll encounter the SI impersonale in Italian:
- To make generic statements and express general truths and facts:
- Nel sud Italia si cena tardi — In southern Italy people have dinner late
- Si impara dagli errori — One learns from their mistakes
- To talk about trends, either current or longstanding:
- Oggigiorno si lavora molto da remoto — Nowadays, remote work is very common
- Una volta non si viaggiava così facilmente — In the past, people didn’t travel so easily
- To state rules, guidelines, or things that are not allowed:
- Qui non si fuma — Smoking is not allowed here
- Non si entra senza biglietto — You cannot enter without a ticket
- To ask or explain how to do something or how to get somewhere:
- Come si arriva al Colosseo da qui? — How do you get to the Colosseum from here?
- Si fa così, guarda — You do it like this, look

- To talk about abstract ideas or speculative scenarios
- Si può essere felici senza amore? — Can one be happy without love?
- Come si vive senza tecnologia? — How does one live without technology?
- To keep things impersonal and discreet when you want to discuss rumors or share information in a vague way, without naming names. Common expressions are si dice (it is said), si sa(it is known), and si pensa(it is thought):
- Si sa chi è stato ma nessuno lo dice — Everyone knows who did it, but no one is saying it
- Si pensa che sia stata la sorella — People think it was the sister
What’s the the difference between SI impersonale and SI passivante in Italian
A common source of confusion in Italian grammar is the use of the pronoun SI in both impersonal and passive sentences. But while these constructions may appear similar due to their patterns, they serve distinct purposes.
The SI impersonale is used to make general statements or describe habits, customs, or actions without specifying a subject. For example, in the sentence Durante i caldi mesi estivi si beve di più (During the warm summer months, people drink more), the focus is on the general habit of drinking more during the summer, without indicating who specifically does the drinking.
The SI passivante, on the other hand, is used to create the passive voice in Italian without mentioning who performs the action. The emphasis, in this case, is on the object being acted upon, as in: Durante l’estate si mangiano molti gelati (During the summer, a lot of gelato is eaten).
To distinguish them, focus on the verb that comes with SI.
- If the verb is intransitive or transitive without an object, it’s a SI impersonale construction
- If the verb is transitive with a clear object, and it’s conjugated either in the third-person singular or plural, it’s a SI passivante construction
Here’s a summary table:
| SI Impersonale vs SI Passivante in Italian | |||
|---|---|---|---|
| Construction | Verb type | Verb conjugation | Example |
| SI IMPERSONALE | Intransitive verb | Only third-person singular | Si parte alle 8 (One leaves at 8) |
| Transitive verb with no object | Only third-person singular | In estate si beve molto (In summer, people drink a lot) |
|
| SI PASSIVANTE | transitive verb with object | Third-person singular or plural | Qui si mangia la fiorentina (Here you can eat the Florentine steak) |
| Stanotte si vedono le stelle (Tonight you can see the stars) |
