English has essentially one tool for hiding or backgrounding the agent: the be-passive ("the bridge was built", "the letter has been sent", "it is said"). Polish has a menu of at least four, and they are not stylistic free choices — each is keyed to a register and a nuance. A learner who only knows zostać + participle (the textbook "passive") will sound stiff in conversation, where the się-passive is natural, and bookish in news writing, where the -no/-to form fits. Choosing the right agent-backgrounding strategy for the register is a genuine C1 skill. This page lays the four side by side, shows the same content rendered each way, and tells you when to reach for which.
The four strategies at a glance
| Strategy | Form | Focus | Register |
|---|---|---|---|
| być | List jest wysłany | Resulting state | Neutral / formal |
zostać
| List został wysłany | The event of it happening | Formal, written, eventive |
| się-passive | Mieszkanie się sprzedaje | Generic / habitual | Colloquial, everyday |
| -no / -to impersonal past | Zbudowano most | Completed past act, agent suppressed | News, history, official |
A fifth, lighter device — impersonal trzeba / można ("one must / one can") plus the infinitive — backgrounds the agent in modal statements. We treat it at the end.
być vs zostać + participle: state vs event
These are the two periphrastic passives, both built on the passive participle, and the difference between them is the difference between a state and an event — a distinction English collapses.
być + participle describes the resulting state: the situation as it now stands.
List jest już wysłany.
The letter is already sent (it's in the sent state now).
Drzwi są zamknięte.
The door is closed (state).
zostać + participle describes the event — the moment the action was carried out, the change taking place.
List został wysłany wczoraj o piątej.
The letter was sent yesterday at five (the act of sending).
Most został zbudowany w 1905 roku.
The bridge was built in 1905 (the construction event).
Notice how the time adverbials sort the two: a precise moment ("yesterday at five", "in 1905") attaches to the event reading, so zostać is correct there; być would clash, because a state does not happen at five o'clock. Conversely, Drzwi są zamknięte ("the door is closed") is about the present state, so być is right and zostały zamknięte would foreground the act of closing. The agent, if mentioned, goes in the instrumental with przez: List został wysłany przez sekretarkę ("…sent by the secretary"). For the mechanics, see the passive with być / zostać.
The się-passive: the everyday default
In conversation, Poles rarely use either periphrastic passive for generic statements. They use the się-passive — a reflexive-looking construction that backgrounds the agent and is the natural choice for habitual, general, "this is how it's done" statements.
Tutaj sprzedaje się świeże pieczywo.
Fresh bread is sold here.
Mieszkanie się sprzedaje.
The flat is for sale / is being sold.
W Polsce dużo się czyta.
In Poland people read a lot.
The word order varies — Sprzedaje się mieszkanie and Mieszkanie się sprzedaje are both fine, with the usual information-structure nuance. What matters is the register: this is the form you reach for in speech, on shop signs, in recipes ("dodaje się sól" — "salt is added"), and anywhere a generic, agentless statement feels conversational. Where an English speaker says "the flat is being sold" with a be-passive, the Pole says mieszkanie się sprzedaje — and using zostaje sprzedawane here would sound oddly officious. For the construction in depth, see impersonal się and the się-passive.
The -no / -to impersonal past: news and history
This is the form English learners most often lack entirely, and it is indispensable for reading and writing Polish news, history, and officialese. The -no / -to ending turns a verb into a tenseless, subjectless, past-referring impersonal: someone (unspecified people) did this.
Zbudowano nowy most nad Wisłą.
A new bridge was built over the Vistula.
Aresztowano trzech podejrzanych.
Three suspects were arrested.
W zeszłym roku otwarto dwie nowe szkoły.
Two new schools were opened last year.
Crucially, the object stays in the accusative (nowy most, trzech podejrzanych, dwie nowe szkoły) — this is not a true passive that promotes the patient to subject; it is an impersonal active with a suppressed human agent. That is why it reads so neutrally: it reports the deed without naming, implying, or grammatically promoting anyone. It is the register of headlines, chronicles, and minutes. Using zostać + participle here is grammatical but heavier and more "documentary"; the -no/-to form is crisper and is what a Polish journalist actually writes. For the form's morphology, see the -no/-to impersonal past.
The same content, four ways
To feel the register grading, here is one idea — "the bridge was built / a bridge is being built" — rendered across the menu:
Most został zbudowany w zeszłym roku.
The bridge was built last year. (zostać — formal, eventive, neutral written)
Zbudowano most w zeszłym roku.
A bridge was built last year. (-no/-to — news/historical, crisp, agent fully suppressed)
Tu się buduje nowy most.
A new bridge is being built here. (się — colloquial, generic, conversational)
Most jest już zbudowany.
The bridge is already built. (być — resulting state, 'it now stands finished')
Same propositional content; four different communicative jobs. Choosing among them is a register decision, and getting it right is exactly the C1 competence this page is about. The dedicated comparison page się-passive vs -no/-to vs zostać drills the choice further; the register overview frames the broader stylistic stakes.
trzeba / można: backgrounding the agent in modal statements
When the proposition is modal — "one must", "one can", "it is necessary / permitted" — Polish uses the impersonal predicatives trzeba ("it is necessary") and można ("one can / it is allowed") plus an infinitive. There is no subject at all; the agent is generic "one / people".
Trzeba to zrobić jeszcze dzisiaj.
This has to be done today / one must do this today.
Tutaj nie można palić.
Smoking is not allowed here / one can't smoke here.
Trzeba uważać na schodach.
One must be careful on the stairs.
Where English reaches for a passive ("this has to be done", "smoking is not permitted"), Polish prefers this agentless modal frame. It is neutral-to-formal and ubiquitous on signs and in instructions. Note that in the past these become trzeba było ("it was necessary") and można było ("one could") — still subjectless.
How to choose: a quick decision guide
- Generic / habitual, conversational ("bread is sold here", "that's not done") → się-passive.
- A specific past event, neutral or formal written ("the contract was signed yesterday") → zostać
- participle.
- News, history, official report; agent fully anonymous ("a bridge was built", "two were arrested") → -no/-to.
- A present resulting state ("the door is closed", "the letter is already sent") → być
- participle.
- Modal "one must / one can" ("this must be done", "no smoking") → trzeba / można
- infinitive.
Common Mistakes
❌ Tutaj jest sprzedawane świeże pieczywo.
Stiff/unnatural for a generic shop statement — Polish uses the się-passive here.
✅ Tutaj sprzedaje się świeże pieczywo.
Fresh bread is sold here.
❌ Most jest zbudowany w 1905 roku.
Wrong focus — a dated occurrence is an event, not a present state; use zostać.
✅ Most został zbudowany w 1905 roku.
The bridge was built in 1905.
❌ Zbudowano nowego mostu.
Incorrect — the -no/-to form keeps the object in the accusative, not the genitive: nowy most.
✅ Zbudowano nowy most.
A new bridge was built.
❌ To musi być zrobione dzisiaj.
Stilted, English-shaped passive — Polish prefers the impersonal modal trzeba.
✅ Trzeba to zrobić dzisiaj.
This has to be done today.
❌ Trzech podejrzanych zostało aresztowanych w zeszłym tygodniu.
Grammatical but bookish for a news report; the crisp journalistic form is -no/-to.
✅ Aresztowano trzech podejrzanych w zeszłym tygodniu.
Three suspects were arrested last week.
Key Takeaways
- English has one be-passive; Polish has a register-graded menu — choosing among them is the C1 skill.
- być
- participle = present state; zostać
- participle = past event (use it when there's a time-of-occurrence adverbial).
- participle = present state; zostać
- The się-passive is the conversational default for generic/habitual statements — not zostać.
- -no/-to is the news/historical impersonal; the object stays accusative (it's an impersonal active, not a true passive).
- For modal "one must / one can", use trzeba / można
- infinitive, not an English-shaped passive.
