Lesson 39: Passive voice and the si construction — how Italian avoids the agent

Part 1: Why you need the passive

In an active clause the subject = the one doing it:

Il cuoco prepara la pizza. — The chef makes the pizza. (subject — the chef, object — the pizza)

In a passive clause the subject = the thing acted on:

La pizza è preparata dal cuoco. — The pizza is made by the chef. (subject — the pizza, agent — by the chef)

Why use this?

Why	Example
Focus on the result, not the doer	La casa è stata costruita nel 1920. — The house was built in 1920.
The agent is unknown	Mi è stata rubata la macchina. — My car was stolen.
The agent is not important	Il documento sarà firmato domani. — The document will be signed tomorrow.
Formal register	Il colpevole è stato arrestato. — The culprit has been arrested.

English-speaker frame: English uses only one passive auxiliary — "be" ("is made", "was built", "will be signed"). Italian uses three: essere (the neutral default, equivalent to English "be"), venire (highlights the process — no clean English match), and andare (carries an obligation flavor — closer to "is to be" or "must be"). Italian also has si-constructions that English handles with whatever fits: "you eat well here", "people eat well here", "one eats well here", or just "they sell tickets at the entrance". Italian compresses all of that into a tiny si.

Part 2: Passive with essere — the main form

Formula

essere (in any tense) + participio passato (agreeing in gender and number with the subject)

This works in every tense, exactly like essere in any other compound form:

Tense	Active	Passive
Presente	Il cuoco prepara la pizza.	La pizza è preparata dal cuoco.
Imperfetto	Il cuoco preparava la pizza.	La pizza era preparata dal cuoco.
Passato prossimo	Il cuoco ha preparato la pizza.	La pizza è stata preparata dal cuoco.
Passato remoto	Il cuoco preparò la pizza.	La pizza fu preparata dal cuoco.
Futuro	Il cuoco preparerà la pizza.	La pizza sarà preparata dal cuoco.
Condizionale	Il cuoco preparerebbe la pizza.	La pizza sarebbe preparata dal cuoco.
Congiuntivo presente	(che) il cuoco prepari la pizza.	(che) la pizza sia preparata dal cuoco.

The key point: the participle always agrees with the subject in gender and number. La pizza è preparata. (fem. sg.) Il dolce è preparato. (masc. sg.) Le pizze sono preparate. (fem. pl.) I dolci sono preparati. (masc. pl.)

The agent — through da

If you want to name by whom the action was done, put da + agent:

Italian	English
La lettera è scritta da Marco.	The letter is written by Marco.
Il libro è stato letto da molti studenti.	The book has been read by many students.
La cena sarà preparata da mia madre.	Dinner will be made by my mother.

Notice: da is the same preposition you use for the agent in active constructions with the infinitive (da fare). Don't confuse it with di (possession).

---

Part 3: Passive with venire — alternative for the process

Formula

venire (in a simple tense) + participio passato (agreed)

Venire works as a passive auxiliary only in simple tenses (presente, imperfetto, futuro, condizionale, passato remoto). In compound tenses (passato prossimo, trapassato, etc.) venire doesn't work — you fall back on essere.

Tense	Passive with essere	Passive with venire
Presente	La pizza è preparata.	La pizza viene preparata.
Imperfetto	La pizza era preparata.	La pizza veniva preparata.
Futuro	La pizza sarà preparata.	La pizza verrà preparata.
Passato prossimo	La pizza è stata preparata.	✗ (only essere)

When to use venire vs essere

essere — more about the result / state	venire — more about the process / regular action
La porta è chiusa. (the door is closed now)	La porta viene chiusa alle otto. (it gets closed every day at eight)
Il pacco è consegnato. (already delivered)	Il pacco viene consegnato ogni mattina. (gets delivered every morning)
I libri sono venduti. (sold)	I libri vengono venduti in libreria. (get sold — wherever that happens)

Memorize: essere is neutral — works everywhere. Venire highlights the action as a process, especially a regular one. When in doubt, take essere. (English collapses both onto plain "be" — La porta è chiusa and La porta viene chiusa alle otto are both "The door is closed".)

Read aloud

La cena viene servita alle otto. I biglietti vengono controllati all'ingresso. La posta veniva consegnata ogni mattina. Il nuovo modello verrà presentato a Milano.

Part 4: Andare + participle — the obligation passive

There's a third passive auxiliary — andare — but it adds the sense of "must be done":

Italian	English
La pasta va cotta dieci minuti.	The pasta needs to be cooked for ten minutes.
Questa lettera va spedita oggi.	This letter must be sent today.
Le regole vanno rispettate.	The rules must be followed.
Il pesce va mangiato fresco.	Fish should be eaten fresh.

Notice: andare + part. = deve essere + part. Very common in instructions, recipes, manuals. English equivalents: "must be", "should be", "is to be".

Fine print: andare as a passive auxiliary works only in simple tenses and only in this "obligation" sense. Don't confuse it with regular andare ("to go").

---

Part 5: The si construction — impersonal and passive

This is the most common way to leave the agent out in Italian. You'll meet it on every shop sign, in every instruction, in every casual chat.

5.1. Si impersonale — impersonal "si"

"One does X", "you / people eat / drink / say" in a general sense, with no specific person in mind.

Formula: si + verb in the 3rd person singular

Italian	English
Si mangia bene qui.	You eat well here. / People eat well here.
Si dorme bene in montagna.	You sleep well in the mountains.
Si vive bene in questa città.	One lives well in this town.
Si lavora molto in Italia.	People work a lot in Italy.
Non si fuma qui.	No smoking here.

Note: this is impersonal — nobody specific is meant. The verb is always 3rd person singular.

English equivalents: there's no single English form for this. You pick from "you / one / people / they / nobody (in negation)" depending on register. "Si mangia bene qui" is "you eat well here" (informal), "one eats well here" (formal), or "the food's great here" (idiomatic). All three map to the same Italian sentence.

5.2. Si passivante — passive "si"

Here si plays the role of a passive: "X is done", "X gets sold / made / said".

Formula: si + verb in 3rd person sg./pl. — agrees with the object!

Italian	English	Explanation
Si parla italiano.	Italian is spoken (here).	italiano — sg. → verb sg.
Si parlano molte lingue.	Many languages are spoken (here).	lingue — pl. → verb pl.
Si vende casa.	House for sale. (sign)	casa — sg.
Si vendono biglietti.	Tickets sold (here).	biglietti — pl.
Si cerca cameriere.	Waiter wanted.	cameriere — sg.
Si cercano insegnanti.	Teachers wanted.	insegnanti — pl.

The agreement rule: in si passivante the verb agrees not with si, but with the object (which grammatically becomes the subject). One object — singular. Many — plural.

The difference between si impersonale and si passivante

Si impersonale	Si passivante
No object (or with an intransitive verb)	With a direct object (with a transitive verb)
Verb always 3rd person sg.	Verb agrees with the object
Si mangia bene. (people eat well — no object)	Si mangia la pizza. (pizza gets eaten — sg.)
Si dorme bene.	Si mangiano gli spaghetti. (spaghetti get eaten — pl.)
Si lavora molto.	Si vendono case. (houses get sold — pl.)

Fine print: in practice the line blurs — native speakers often say si mangia gli spaghetti in casual speech. But in standard usage, agree with the object.

Read aloud — typical signs

Si vende. — For sale. Si affitta. — For rent. Si parla inglese. — English spoken. Si lavora bene. — Pleasant place to work. Si mangia bene. — Good food. Non si fuma. — No smoking.

Part 6: Si in compound tenses — a wrinkle

When the si-construction sits in a compound tense (passato prossimo, etc.), the auxiliary is always essere, and the participle follows some specific rules.

Si impersonale in passato prossimo

With intransitive verbs (which usually take avere), the participle goes into masculine plural:

Italian	English
Si è mangiato molto.	People ate a lot.
Si è lavorato tutto il giorno.	We worked all day.
Si è parlato di tutto.	All sorts of things were talked about.

With verbs that usually take essere, the participle goes into the plural:

Italian	English
Si è andati al cinema.	We went to the cinema.
Si è arrivati tardi.	We arrived late.
Si è partiti presto.	We left early.

Memorize: si è andati (not si è andato), si è partiti (not si è partito). This is obligatory agreement, even when "we" is only implied.

Si passivante in passato prossimo

essere + participle, agreeing with the object:

Italian	English
Si è venduta la casa.	The house has been sold.
Si sono vendute le case.	The houses have been sold.
Si è letto il libro.	The book has been read.
Si sono lette le lettere.	The letters have been read.

Fine print: the participle agrees with the object in both gender (letto / lette) and number (venduta / vendute).

---

Part 7: Which construction to pick — a quick test

Subject is alive and important → active voice. Object matters more than the agent, and the agent is named → essere + part. + da + agent. Object matters, agent unimportant / unknown → si passivante or essere/venire + part. Verb is intransitive, no object → si impersonale. Obligation → andare + part.

Compare — one meaning, different forms

"In this restaurant they make excellent pizza":

Form	Italian
Active (with subject)	In questo ristorante preparano un'ottima pizza.
Passive (essere)	In questo ristorante l'ottima pizza è preparata. (sounds formal)
Passive (venire)	In questo ristorante viene preparata un'ottima pizza.
Si passivante	In questo ristorante si prepara un'ottima pizza. (the most natural)
Si impersonale (focus on "great food")	In questo ristorante si mangia benissimo. (no object)

The B2 takeaway: for everyday speech, reach for si passivante. It's the most frequent, most Italian-sounding form.
