Danish builds the passive two ways, and choosing the wrong one makes a sentence sound subtly off even when it is grammatical. The -s passive attaches -s to the verb (Bøger læses — "books are read"). The blive-passive uses the auxiliary blive + past participle (Bogen blev læst — "the book was read"). English has only one passive ("is/was read"), so it gives you no instinct for the split. The good news is that one clean question sorts most cases instantly.
The one-line decision test
Is this a general/habitual/rule-like statement, or a single concrete event?
- General truth, habit, rule, instruction, or an infinitive after a modal → -s passive.
- One specific, concrete, dynamic event that happened (or will happen) at a particular moment → blive-passive.
| -s passive | blive-passive | |
|---|---|---|
| Form | verb + -s | blive
|
| Use for | general truths, habits, rules, instructions, infinitives | a single concrete dynamic event |
| Time feel | timeless / repeated | pinned to a moment |
| Typical with agent (af)? | rare | common |
| Example | Døren åbnes automatisk. | Døren blev åbnet af vagten. |
Bøger læses bedst i stilhed.
Books are read best in silence. (general truth — -s passive)
Bogen blev læst højt for klassen.
The book was read aloud to the class. (one concrete event — blive-passive)
When to use the -s passive
General truths and habitual actions
The -s passive presents the action as a standing fact, not tied to any one occasion. This is its home territory.
Øl brygges af malt, humle og vand.
Beer is brewed from malt, hops and water. (a general truth)
Avisen leveres hver morgen klokken seks.
The paper is delivered every morning at six. (a habit)
Rules, regulations, instructions
Signs, recipes, manuals, and official notices overwhelmingly use the -s passive. It reads as impersonal and authoritative.
Døren åbnes automatisk.
The door opens automatically. (instruction on a sign)
Cykler fjernes uden varsel.
Bicycles will be removed without notice. (a rule)
Tilsæt salt og lad det koge — derefter sies suppen.
Add salt and let it boil — then the soup is strained. (recipe instruction)
Infinitives, especially after modal verbs
After kunne, skulle, måtte, burde and other modals, the passive infinitive almost always takes the -s form. The blive-infinitive (blive gjort) exists but sounds heavier and is used far less here.
Det kan gøres på ti minutter.
It can be done in ten minutes. (-s passive infinitive after 'kan')
Arbejdet skal afleveres inden fredag.
The work must be submitted before Friday.
When to use the blive-passive
The blive-passive describes a single, concrete, dynamic event — something that happened at a specific point, often with a nameable doer. It is the form that narrates: X happened to Y.
Døren blev åbnet af vagten.
The door was opened by the guard. (one event, with an agent)
Han blev fyret i går.
He was fired yesterday. (a single dated event)
Vinderen blev kåret efter en lang afstemning.
The winner was chosen after a long vote.
Because it foregrounds the moment of the event, blive-passive pairs naturally with time markers (i går, klokken to, pludselig) and with an af-phrase naming the agent.
Both contrast with være: don't confuse the event with the state
There is a third construction — være + past participle — that you must keep separate. Blive marks the event (the change happening); være marks the resulting state (the condition afterwards). This is the famous blive/være split.
Døren blev åbnet klokken otte.
The door was opened at eight. (the act of opening — blive)
Døren var åben hele dagen.
The door was open all day. (the resulting state — note 'åben', an adjective, not the participle)
Vinduet blev knust af stormen.
The window was shattered by the storm. (event)
Vinduet var knust, da jeg kom hjem.
The window was (already) shattered when I got home. (state I found it in)
So you are really choosing among three: -s for the general/timeless passive, blive for the concrete event, være for the state that results.
Near-identical frames
Put the same verb into both passives and the meaning shifts predictably — timeless rule vs one-off event.
Maden serveres klokken syv.
Dinner is served at seven. (the standing arrangement — -s)
Maden blev serveret klokken syv.
Dinner was served at seven. (it happened, on this occasion — blive)
Reglerne overholdes af alle medarbejdere.
The rules are observed by all employees. (general policy — -s)
Reglen blev overtrådt to gange i går.
The rule was broken twice yesterday. (specific events — blive)
A note for English speakers
English uses one passive for both jobs ("is read / was read"), distinguishing general from specific only through tense and adverbs. Danish makes the distinction morphological: it chooses a different construction depending on whether you mean a rule or an event. So when you translate an English passive, don't just match the tense — ask which kind of statement is this? A timeless or rule-like English present passive almost always becomes Danish -s; a narrated past event almost always becomes Danish blive.
Common Mistakes
❌ Han fyres i går.
Incorrect — 'i går' pins this to a single past event, so the -s passive (which reads as habitual/general) clashes.
✅ Han blev fyret i går.
He was fired yesterday.
❌ Bøger blives læst i skolen.
Incorrect — a general truth about books should use the -s passive, and 'blives' is not even a valid form.
✅ Bøger læses i skolen.
Books are read in school.
❌ Døren bliver åbnet automatisk.
Awkward — for a standing instruction on a sign, Danish strongly prefers the -s passive.
✅ Døren åbnes automatisk.
The door opens automatically.
❌ Vinduet blev knust hele dagen.
Incorrect — 'hele dagen' describes a lasting state, which needs 'være', not the event-verb 'blive'.
✅ Vinduet var knust hele dagen.
The window was shattered all day. (state)
❌ Det kan blive gjort på ti minutter.
Unnatural here — after a modal, Danish prefers the -s passive infinitive.
✅ Det kan gøres på ti minutter.
It can be done in ten minutes.
Key Takeaways
- -s passive = general truths, habits, rules, instructions, and infinitives after modals. Timeless and impersonal.
- blive-passive = a single concrete dynamic event, often with a time marker or an af-agent.
- Keep være
- participle separate: it marks the resulting state, not the event.
- One test: rule or event? Rule → -s; event → blive; the state left behind → være.
- Don't translate an English passive by tense alone — decide whether it's a standing fact or a one-off occurrence first.
