🔍 In short. The italian ci si construction happens when two si words try to share the same spot in a sentence. The reflexive verb already comes with its own si (lavarsi, vedersi, alzarsi), and the impersonal “one” also wants a si. Italian refuses to say si si lava, so the first si turns into ci: ci si lava, ci si vede, ci si alza. The verb stays singular, even when an object follows in the plural: ci si lava le mani (not ci si lavano). In the past, the participle goes masculine plural by default: ci si è alzati, ci si è visti. Master the italian ci si construction and a whole layer of natural Italian opens up: ci si vede domani, ci si abitua a tutto, ci si stanca presto.
This B2 guide walks through the italian ci si construction step by step: why Italian swaps the first si for ci, what the verb does when an object turns up, how the past participle picks gender, and how ci si vede hides a friendly farewell. A Padova morning dialogue between Massimo and Costanza shows the italian ci si construction working at conversational speed.

Why two si words cannot share a sentence
Walk into a bar in Padova on a Saturday morning and listen. Someone behind you will say qui ci si trova bene, the barista will throw a quick ci si vede at a regular leaving with the newspaper, and a mother at the next table will tell her son ci si lava le mani prima di mangiare. Three sentences, three little oddities. In every one of them the italian ci si construction is doing the same job: keeping the impersonal “one” intact when the verb already carries its own reflexive si.
The starting point is simple. Italian uses si two ways. The first si is reflexive: it means the subject acts on itself. Mario si lava = Mario washes himself. The second si is impersonal: it stands for a generic “one” or “people in general”. Si mangia bene a Padova = people eat well in Padova. Each si has its own job, and most sentences use only one of them. Trouble starts when both want to show up in the same sentence.
Say you want to express “people wash themselves before lunch” with the impersonal “one” plus the reflexive verb lavarsi. The logic would point you toward si si lava: one (impersonal si) plus oneself (reflexive si). But Italian refuses. Two identical si words next to each other sound impossible to the native ear, and the language solved the problem centuries ago by swapping the first one for ci. The result is the italian ci si construction: ci si lava. The meaning is exactly what the doubled si would have meant, with no ambiguity for any native speaker.
How the italian ci si construction works
The recipe for the italian ci si construction has three ingredients and one rule. Take an impersonal sentence with “one” or “people in general”, pick a reflexive verb, and put ci in front of the verb’s own si. The verb stays in the third person singular, no matter what comes after it.
- Ci si alza presto a Padova in estate, fa caldo già alle sette.
People get up early in Padova in summer, it’s already hot by seven. - Ci si abitua a tutto, anche al freddo del Veneto.
One gets used to everything, even the Veneto cold. - In una città tranquilla ci si annoia presto.
In a quiet town one gets bored quickly. - Ci si stanca a stare in piedi tutto il giorno al mercato.
You get tired standing all day at the market. - Ci si pente sempre di non aver dormito abbastanza.
One always regrets not having slept enough.
Notice the English translations. Sometimes “one”, sometimes “people”, sometimes “you” (the generic English you, not the addressee). The italian ci si construction covers all three in a single form. It picks up where the bare impersonal si stops and lets reflexive verbs join the impersonal family.
🔍 The swap rule. When the impersonal si meets a reflexive verb, change the first si into ci. The verb stays singular. That is the italian ci si construction in one line. Si plus si lava would be impossible; ci si lava is what every Italian uses without thinking.
Side by side: reflexive si vs ci si
The cleanest way to read the italian ci si construction is to put the regular reflexive sentence next to the impersonal version. Same verb, two different subjects: a specific person on the left, a generic “one” or “people” on the right. The only thing that changes is the pronoun cluster in front of the verb.
| Regular reflexive (specific subject) | Italian ci si construction (impersonal) | English meaning of the impersonal |
|---|---|---|
| Massimo si lava le mani. | Ci si lava le mani. | One washes one’s hands. |
| Costanza si veste in fretta. | Ci si veste in fretta quando si è in ritardo. | People dress in a hurry when they’re running late. |
| Mio fratello si alza alle sei. | Ci si alza presto d’estate. | People get up early in summer. |
| Lei si annoia in ufficio. | Ci si annoia se non si esce mai. | You get bored if you never go out. |
| Si abitua al rumore. | Ci si abitua a tutto. | One gets used to everything. |
| Si pente di averlo detto. | Ci si pente quasi sempre delle parole, mai dei silenzi. | One almost always regrets words, never silences. |
| Si dimentica il cappello. | Ci si dimentica facilmente delle promesse. | People easily forget promises. |
| Si vede allo specchio. | Ci si vede domani in Prato della Valle. | We’ll see each other tomorrow at Prato della Valle. |
Read the right column out loud a few times. The pattern ci si + singular verb starts to feel automatic. That is the goal: not memorising a rule, but hearing the italian ci si construction the same way an Italian does, as a perfectly normal opening to a sentence about people in general.
🎯 Mini-task #1. Turn each personal sentence into the italian ci si construction with a general subject.
- Massimo si lava le mani.
- Costanza si stanca facilmente.

Adding an object: ci si lava le mani
Here is the spot where the italian ci si construction surprises every learner. When a direct object joins the sentence, you might expect the verb to match it: ci si lava le mani looks plural, so why not ci si lavano le mani? The answer is that the verb stays singular. The italian ci si construction freezes the verb in the third person singular regardless of what follows.
- A casa mia ci si lava le mani prima di mangiare.
At my house people wash their hands before eating. - In Veneto ci si toglie le scarpe entrando in casa.
In Veneto people take off their shoes when they come into the house. - Al mattino ci si lava i denti prima del caffè.
In the morning people brush their teeth before coffee. - D’inverno ci si mette i guanti e la sciarpa.
In winter you put on gloves and a scarf. - In montagna ci si copre la testa anche a maggio.
In the mountains you cover your head even in May.
The plural noun (le mani, le scarpe, i denti, i guanti) sits right after the verb, but the verb itself does not move. Ci si lavano le mani is a real mistake, often heard from learners who try to apply the si passivante rule by accident. Stick to the singular: the italian ci si construction does not behave like si passivante.
Why does Italian freeze the verb? Because the focus of the sentence is the people doing the washing, not the hands. The hands are the body parts those people own, expressed by the reflexive verb lavarsi. The italian ci si construction signals “generic people performing a reflexive action on themselves”, and that action stays singular even when its object is plural.
Past tense: ci si è alzati or alzate
In compound tenses the italian ci si construction throws one more curve. Reflexive verbs always take essere, so the auxiliary is è: ci si è alzati, ci si è lavati, ci si è visti. The participle then needs a gender and a number, and Italian solved that by sending it masculine plural as the default. The implied “people” of the impersonal si is treated as a generic crowd.
- Domenica scorsa ci si è alzati tardi e ci si è goduti la mattinata.
Last Sunday people slept in and enjoyed the morning. - Dopo il trasloco ci si è dovuti adattare al rumore della tangenziale.
After the move you had to get used to the noise from the ring road. - Una volta arrivati in albergo, ci si è lavati e cambiati in fretta.
Once we got to the hotel, people washed and changed in a hurry. - Ci si è abituati al nuovo orario in pochi giorni.
People got used to the new schedule in a few days. - Ci si è visti per la prima volta a una cena in Prato della Valle.
We first saw each other at a dinner in Prato della Valle.
What if the implied crowd is all women? Italian allows the feminine plural participle in that case: ci si è alzate, ci si è viste. You hear it when context already names a group of women, for instance in a recap of a girls’ weekend: il sabato ci si è alzate tardi, la domenica ci si è viste tutte al brunch. Without that explicit context, the masculine plural is the unmarked default. Italian treats the generic “people” as masculine plural the same way it treats quando si è giovani, with the adjective in masculine plural by default.
🔍 Past-tense recipe. Auxiliary è, participle masculine plural by default (alzati, lavati, visti, abituati), feminine plural only when the group is explicitly all female. Verb still singular in form: è, not sono.
Ci si vede: the farewell trick
Stop at a bar in Padova, pay for your espresso, and as you turn to leave you might hear ci si vede from the owner or another regular. It is one of the most common Italian farewells you never learn in a textbook. Literally the italian ci si construction with vedersi means “one sees oneself”, which is nonsense in English. The real meaning is “we’ll see each other around”, a relaxed, slightly indefinite “see you later”.
- Ciao, ci si vede domani in università.
Bye, see you tomorrow at the university. - Allora ci si sente più tardi, ti chiamo io.
OK, talk to you later, I’ll call you. - Ci si trova bene in questo quartiere di Padova.
You feel at home in this neighborhood of Padova. - Davanti a un caffè in piazza dei Signori ci si conosce meglio.
Over a coffee in piazza dei Signori people get to know each other better. - A Padova in centro ci si saluta ancora per strada.
In central Padova people still greet each other on the street.
With verbs that already have a reciprocal flavour (vedersi, sentirsi, conoscersi, salutarsi, incontrarsi, trovarsi), the italian ci si construction slides toward the meaning “each other”. Ci si vede means “we see each other” or “people see each other”. The friendly farewell ci si vede picks up the “we” reading because the speaker and listener are obviously included in that “people”. The italian ci si construction stays the same; only the social context picks the reading.
Ci si vs si passivante: don’t mix them
Two patterns share the small word si and end up confused. The italian ci si construction sits on reflexive verbs and stays singular. The si passivante sits on transitive verbs and goes plural when its object is plural. Mix them up and the sentence breaks.
- Si affittano biciclette in piazza dei Signori. (si passivante, plural verb, agrees with biciclette)
- Ci si lava le mani prima di sedersi a tavola. (italian ci si construction, singular verb, ignores le mani)
- Si vendono libri usati al mercato del sabato. (si passivante, plural)
- Ci si toglie le scarpe entrando. (italian ci si construction, singular)
The test is the verb itself. Is it reflexive (lavarsi, togliersi, mettersi, vestirsi)? Then the italian ci si construction applies and the verb stays singular. Is it a plain transitive verb (vendere, affittare, cercare, cucinare)? Then si passivante applies and the verb agrees with its object. Two different toolkits, two different jobs. The full story on the plural side lives in our guide to si passivante plural; the sister rule on quando si è giovani and adjective agreement lives in the si impersonal plural adjective guide.

Three common slips
Three errors flag a B2 sentence as written by a learner who has not internalised the italian ci si construction. Fixing them is fast and worth the effort.
Slip 1. Writing si si lava. Italian never accepts two identical si in a row. The italian ci si construction swaps the first one for ci: ci si lava. If you find yourself about to type two si, stop and switch.
Slip 2. Making the verb agree with a plural object. Wrong: ci si lavano le mani. Correct: ci si lava le mani. The italian ci si construction freezes the verb in the third person singular even when a plural noun follows. That is the rule that separates the italian ci si construction from si passivante.
Slip 3. Using ha or hanno in the past. Wrong: ci si ha alzati. Reflexive verbs take essere, so the italian ci si construction in the past uses è: ci si è alzati, ci si è visti, ci si è goduti la serata. Verb stays singular, participle goes masculine plural by default.
🎯 Mini-task #2. Fix or confirm each sentence.
- A casa nostra si si lava le mani prima di mangiare.
- Ci si lavano i denti due volte al giorno.
- Ci si è alzati tardi domenica mattina.
- Ci si ha visti al mercato sabato scorso.
- Ci si abitua a tutto, anche al traffico di Padova.
- D’inverno ci si mettono i guanti.

👨🏽🦱 Massimo: Buongiorno. Ti sei alzata presto oggi, le sei e mezza.
Morning. You got up early today, six thirty.
👩🏽🦱 Costanza: A Padova d’estate ci si alza presto, lo sai. Con questo caldo, alle otto in camera non si respira più.
In Padova in summer people get up early, you know that. With this heat, by eight you can’t breathe in the bedroom anymore.
👨🏽🦱 Massimo: Vero. Eppure ci si abitua, dopo qualche anno. Il primo agosto qui mi sembrava impossibile, adesso quasi non lo sento.
True. And yet you get used to it after a few years. My first August here felt impossible, now I barely notice it.
👩🏽🦱 Costanza: Senti, prima di colazione ci si lava i denti o dopo? Ho letto due cose opposte la settimana scorsa.
Listen, do people brush their teeth before breakfast or after? I read two opposite things last week.
👨🏽🦱 Massimo: Il dentista mio dice dopo, perché altrimenti l’acido del caffè e dell’arancia resta. Però mia madre diceva sempre il contrario.
My dentist says after, because otherwise the acid from coffee and orange juice stays. But my mother always said the opposite.
👩🏽🦱 Costanza: Allora ci si pente di non averlo chiesto prima. Va beh, oggi proviamo dopo. A che ora ci si vede stasera?
So you regret not having asked sooner. Oh well, today we try after. What time do we see each other tonight?
👨🏽🦱 Massimo: Esco dallo studio alle sette. Ci si trova in Prato della Valle alle sette e mezza? C’è la festa dei vicini.
I leave the office at seven. Shall we meet at Prato della Valle at seven thirty? There’s the neighbours’ party.

Perfect. Last Sunday, remember, we got to know each other better over that glass of prosecco. Let’s hope there’s some tonight too.
👨🏽🦱 Massimo: Mi raccomando, non in ritardo. Quando ci si veste in fretta poi si dimentica sempre qualcosa.
Please, don’t be late. When you dress in a hurry you always forget something.
👩🏽🦱 Costanza: Tranquillo. Allora ci si vede dopo. Buona giornata.
Don’t worry. See you later. Have a good day.
👨🏽🦱 Massimo: Ci si sente nel pomeriggio se serve. Ciao.

Frequently asked questions
Six questions about the italian ci si construction come up in every B2 cohort. The answers below draw on real classroom usage and on the Treccani note on si impersonale with reflexive verbs.
Why does Italian say ci si lava and not si si lava?
Because Italian refuses to put two identical si words next to each other. When the impersonal si meets a reflexive verb that already carries its own si, the first si turns into ci. The result is the italian ci si construction: ci si lava, ci si veste, ci si alza. The meaning is exactly the doubled si would have carried, with no ambiguity for native speakers. The swap is automatic and happens every time the two si pronouns would otherwise collide.
Does the verb agree with a plural object after ci si?
No. The italian ci si construction freezes the verb in the third person singular regardless of what follows. A casa mia ci si lava le mani is correct; ci si lavano le mani is wrong, even though le mani is plural. The same applies to ci si toglie le scarpe, ci si lava i denti, ci si mette i guanti. This is the rule that separates the italian ci si construction from si passivante, which does go plural with a plural object (si vendono libri).
How do I form the past tense with ci si?
Reflexive verbs always take essere, so the italian ci si construction in the past uses è: ci si è alzati, ci si è lavati, ci si è visti. The verb form stays singular (è, not sono), but the past participle goes masculine plural by default: alzati, lavati, abituati. If the implied group is explicitly all female, you can use the feminine plural: ci si è alzate, ci si è viste. Without explicit female context, masculine plural is the standard form.
Does ci si vede mean one sees oneself or we see each other?
Context decides. With verbs that already have a reciprocal flavour like vedersi, sentirsi, conoscersi, salutarsi, incontrarsi, the italian ci si construction slides toward the each-other reading. The friendly farewell ci si vede picks up that reading because the speaker and listener are obviously included in the people group. Ci si vede domani means see you tomorrow; ci si sente più tardi means we’ll be in touch later. Both are idiomatic everyday goodbyes.
Is the italian ci si construction the same as quando si è giovani?
No, they cover different parts of the same family. The italian ci si construction handles reflexive verbs: ci si lava, ci si alza. The quando si è giovani pattern handles essere plus an adjective or noun in impersonal sentences and sends the adjective to masculine plural. Quando si è giovani si fanno scelte rapide. The two patterns sit next to each other in real Italian and often appear in the same paragraph, but they answer different grammar questions.
Can I say ci si è alzate with a feminine plural participle?
Yes, when the implied group is explicitly all female. If a recap describes a girls’ weekend, ci si è alzate tardi e ci si è viste tutte al brunch is fully natural. Italian allows the feminine plural participle whenever the context makes clear that the generic people of the italian ci si construction are all women. Without that context, the masculine plural is the unmarked default, the same default Italian uses for any mixed or unspecified group.
