si (passivante)
Passive 'Si' (Si Passivante)
The si passivante is the most common way to express the passive voice in everyday Italian. It focuses on the action or the object rather than who is doing it (e.g., 'Apples are eaten' instead of 'I eat apples').
How It Works
The si passivante (Passivating 'si') allows you to turn a transitive sentence into a passive one without using the formal passivo con essere construction.
Key Rules:
- Transitive Verbs Only: It only works with verbs that take a direct object (like vendere, dire, mangiare).
- 3rd Person Only: This construction is strictly limited to the 3rd person singular or plural.
- Agreement: The noun following the verb is technically the grammatical subject. Therefore, the verb must agree with it. If the noun is plural, the verb is plural (Si vendono le case). If the noun is singular, the verb is singular (Si vende la casa).
- The 'Se Ne' Rule: When used with the ne partitivo, the 'si' changes to 'se' (e.g., Se ne dicono tante - Many [things] are said).
- Modal Verbs: If you use modal verbs, the modal verb must also agree in number with the noun (e.g., Si possono vedere le stelle).
- Compound Tenses: In tenses like the passato prossimo, you must use essere as the auxiliary. The past participle must also agree in gender and number with the noun (Si sono vendute le case).
- No Agent: You cannot use this construction if you want to name the person doing the action (e.g., you cannot say 'by Marco').
Difference from Impersonal 'si':
While si impersonale always uses a singular verb (In Italia si mangia bene), the si passivante changes based on the number of the noun (Si mangiano gli spaghetti).
Examples (6)
- In questo ufficio si parlano tre lingue.
Three languages are spoken in this office.
Word by Word: In this office 'si' speak three languages.
The verb 'parlano' is plural because it agrees with 'tre lingue' (three languages).
- Come si scrive questa parola?
How is this word written? (How do you spell this word?)
Word by Word: How 'si' writes this word?
A very common use of the si passivante to ask for instructions or spelling.
- Si devono spedire le lettere entro stasera.
The letters must be sent by tonight.
Word by Word: 'Si' must send the letters by tonight.
When using modal verbs, the modal itself must agree with the plural noun 'le lettere'.
- Si sono vendute tutte le macchine.
All the cars have been sold.
Word by Word: 'Si' are sold all the cars.
In compound tenses, we use 'essere'. Note how 'vendute' (feminine plural) agrees with 'le macchine'.
- Non si è saputa la verità per molti anni.
The truth was not known for many years.
Word by Word: Not 'si' is known the truth for many years.
The past participle 'saputa' agrees with the singular feminine noun 'la verità'.
- Affittasi appartamento.
Apartment for rent (Apartment is being rented).
Word by Word: Rents-itself apartment.
In formal signs, the 'si' is often attached to the end of the verb (Enclitic).
Common Mistakes
Failing to agree the verb with a plural noun.
Si vende i libri.Si vendono i libri.Because 'i libri' is plural, the verb must be plural ('vendono'). Using the singular is a common error influenced by the impersonal 'si'.
Using 'si ne' instead of 'se ne' with the partitive.
Si ne vendono molte.Se ne vendono molte.When the ne partitivo is used with the passive 'si', the 'si' changes to 'se'.
Adding 'da Marco' to a si passivante.
Different MeaningSi vendono libri da Marco.Marco vende i libri. / I libri sono venduti da Marco.'Si vendono libri da Marco' is correct, but 'da Marco' reads as a place: at Marco's shop. The si passivante has no agent. To say Marco is the seller, use the active voice or the passive with 'essere'.
How It Connects
Learn This First
To understand the 'si passivante', a learner must be familiar with the reflexive particle 'si' and basic verb conjugation in the third person. Additionally, a conceptual understanding of the passive voice helps in recognizing that the object of the action becomes the grammatical subject that the verb must agree with.

The 'si passivante' uses the reflexive particle 'si' and follows the same placement rules as reflexive verbs.
Level 1 - essere + Past Participle + da + AgentPassive Voice with 'Essere'
Understanding the general concept of the passive voice is essential to recognize how 'si' can function as a passive marker.
