S-Passive in Danish

In Brief

Danish forms the s-passive by replacing the present-tense -r with -s, or by adding -s to the infinitive: bygger → bygges (“is being built”), sælger → sælges (“is sold”). It is especially common in rules, signs, instructions, general statements, and formal writing. For a specific completed event, Danish often prefers blive + past participle: Bilen blev solgt i går (“The car was sold yesterday”).

Overview

The passive voice presents an action from the perspective of the person or thing affected by it. Compare active Firmaet bygger huset (“The company is building the house”) with passive Huset bygges (“The house is being built”). In the passive sentence, the house becomes the subject (the person or thing that the sentence is built around), while the builders can remain unmentioned.

Danish has a compact one-word passive called the s-passive (s-passiv). Its final -s does the work for which English normally needs “be” plus a past participle (a verb form such as “built,” “sold,” or “written”). This difference matters: Døren lukkes kl. 22 contains only one Danish verb, but its natural English translation may be “The door is closed at 10 p.m.”

The core pattern belongs at B1 because it appears constantly in public and practical Danish: Der må ikke ryges (“No smoking”), Billetter købes online (“Tickets are bought online”), and Dansk tales her (“Danish is spoken here”). Recognition is essential. In conversation, however, a sentence with blive may sound more natural when you are telling someone about one particular event.

How It Works

From active sentence to passive sentence

An active sentence usually has a doer and an object (the person or thing directly affected by the action):

• Mekanikeren reparerer bilen. — “The mechanic repairs the car.”

To make it passive, put the affected object first and change the verb:

• Bilen repareres. — “The car is repaired / is being repaired.”

The original doer can be omitted. If it matters, add it with af (“by”):

• Bilen repareres af en lokal mekaniker. — “The car is repaired by a local mechanic.”

The present s-passive

The safest practical rule is: start from the infinitive—the dictionary form—and add -s. Another way to see the same pattern is to remove the active present ending -r and use -s instead.

Infinitive	Present active	Present s-passive	Meaning
bygge	bygger	bygges	is built / is being built
sælge	sælger	sælges	is sold
læse	læser	læses	is read
åbne	åbner	åbnes	is opened / opens
lukke	lukker	lukkes	is closed / closes
bruge	bruger	bruges	is used
betale	betaler	betales	is paid
skrive	skriver	skrives	is written

Do not attach -s to the full present form: the passive of bygger is bygges, not byggers. Danish is replacing one ending with another.

The passive infinitive

After a modal verb (a verb such as “must,” “can,” or “should” that modifies another verb), Danish uses the passive infinitive ending in -s:

• Døren skal lukkes. — “The door must be closed.”
• Billetten kan købes online. — “The ticket can be bought online.”
• Skemaet skal udfyldes tydeligt. — “The form must be completed clearly.”
• Medicinen bør tages med mad. — “The medicine should be taken with food.”

This pattern is extremely common because instructions focus on what must happen, not on who must do it.

The same passive infinitive can follow other constructions requiring an infinitive:

• Problemet forsøges løst hurtigst muligt. — “An attempt is being made to solve the problem as quickly as possible.”

That last type is formal and need not be part of your everyday B1 production.

Past forms

A past s-passive exists. It is generally made from the active past form plus -s:

Infinitive	Active past	Past s-passive	Meaning
bygge	byggede	byggedes	was built
åbne	åbnede	åbnedes	was opened
sælge	solgte	solgtes	was sold
skrive	skrev	skreves	was written

These forms are correct, but many sound literary, historical, bureaucratic, or compressed in modern usage. In ordinary speech, especially for one completed event, blive + past participle is normally easier and more natural:

• formal or narrative: Broen åbnedes i 1935.
• everyday neutral: Broen blev åbnet i 1935.

This explains why Bilen blev solgt i går is an important example in this topic even though it is not itself an s-passive: it shows the usual alternative for a specific past event.

Word order and negation

An s-passive is still a finite Danish verb, so normal main-clause word order applies. In a simple main clause, ikke normally comes after the finite verb:

• Døren åbnes ikke om søndagen. — “The door is not opened on Sundays.”
• Her serveres der ikke alkohol. — “Alcohol is not served here.”

In a subordinate clause (a clause introduced by a word such as at or fordi), ikke generally comes before the finite verb:

• Vi kan se, at døren ikke åbnes om søndagen. — “We can see that the door is not opened on Sundays.”

Examples in Context

Danish	English	Note
Huset bygges nu.	The house is being built now.	A process happening now
Døren lukkes kl. 22.	The door is closed at 10 p.m.	A scheduled routine
Dansk tales her.	Danish is spoken here.	General fact; formal wording
Butikken åbnes kl. 9.	The shop is opened at 9 a.m.	Schedule or routine
Billetter købes på hjemmesiden.	Tickets are bought on the website.	Instructional information
Ansøgningen sendes senest fredag.	The application must be sent by Friday.	Present passive with implied requirement
Der må ikke ryges i bygningen.	Smoking is not allowed in the building.	Impersonal rule with der
Maden serveres mellem kl. 18 og 21.	Food is served between 6 and 9 p.m.	Service information
Prisen beregnes automatisk.	The price is calculated automatically.	Process description
Alle personoplysninger behandles fortroligt.	All personal data is handled confidentially.	Formal policy language
Pakken kan afhentes i morgen.	The parcel can be collected tomorrow.	Passive infinitive after kan
Formularen skal underskrives af begge parter.	The form must be signed by both parties.	Named agents with af
Broen byggedes i det nittende århundrede.	The bridge was built in the nineteenth century.	Formal or historical past s-passive
Bilen blev solgt i går.	The car was sold yesterday.	Blive-passive preferred for a specific event

English translations are not always word-for-word. Depending on context, a Danish present s-passive can correspond to “is done,” “is being done,” “gets done,” or even an instruction with “must.” Danish Ansøgningen sendes senest fredag states the procedure compactly; English often makes the obligation explicit.

Common Mistakes

Adding -s to the present-tense form

• Wrong: Huset byggers nu.
• Right: Huset bygges nu.
• Why: Use the infinitive bygge + -s, or replace present -r in bygger with -s.

Using the active verb when the subject receives the action

• Wrong: Billetten køber online.
• Right: Billetten købes online.
• Why: The ticket does not perform the buying. It is the affected thing, so the verb must be passive.

Copying English “is” into an s-passive

• Wrong: Huset er bygges nu.
• Right: Huset bygges nu.
• Why: The -s already marks the passive. Do not place er before a finite s-passive. Huset er bygget is a different construction and often describes the resulting state: “The house is built.”

Using a past s-passive in every past narrative

• Less natural in everyday speech: Bilen solgtes i går.
• Usually natural: Bilen blev solgt i går.
• Why: Solgtes is grammatical, but it can sound compressed or formal. A specific past event commonly takes blev solgt.

Treating every verb ending in -s as passive

• Mistaken analysis: Vi mødes kl. otte = “We are met at eight.”
• Correct meaning: Vi mødes kl. otte = “We meet at eight.”
• Why: Some Danish verbs ending in -s express reciprocal action (“each other”), a state, or a lexical meaning of their own. Form alone does not always prove that a sentence is passive.

Naming an agent when an active sentence is clearer

• Heavy: Rapporten skrives af Maria i dag.
• Often clearer: Maria skriver rapporten i dag.
• Why: A passive is useful when the report is the topic or Maria is secondary. If the doer is the important new information, the active sentence is often more direct.

Usage Notes

Where the s-passive sounds natural

The s-passive is strongly associated with situations that present an action as a procedure, rule, repeated event, or general fact. You will see it in:

• signs and notices: Døren holdes lukket (“Keep the door closed”);
• instructions: Ingredienserne blandes grundigt (“Mix the ingredients thoroughly”);
• schedules: Museet åbnes kl. 10 (“The museum opens at 10 a.m.”);
• policies and administration: Oplysningerne opbevares sikkert (“The information is stored securely”);
• descriptions of systems or processes: Vandet opvarmes til 80 grader (“The water is heated to 80 degrees”).

It is not limited to very formal prose. Short practical notices use it precisely because it is economical and impersonal. However, a long sequence of passives can make ordinary conversation sound distant or administrative.

Present form, several English meanings

Danish does not mark the English distinction between “is built” and “is being built” inside the present s-passive itself. Context and time expressions settle the meaning:

• Huset bygges nu. — “The house is being built now.”
• Husene bygges på fabrikken. — “The houses are built at the factory.”

English also often uses an active intransitive verb where Danish uses an s-passive on a schedule: Døren lukkes kl. 22 may naturally become “The door closes at 10 p.m.” Do not assume that every correct translation must visibly contain “is” or “be.”

Expressing the doer with af

An agent (the doer in a passive sentence) can be introduced with af:

• Loven vedtages af Folketinget. — “The law is passed by the Danish Parliament.”

The phrase is possible, but the s-passive often appears specifically because the doer is obvious or irrelevant. If the agent is central, Danish may prefer an active sentence or a blive-passive, depending on the context.

Beyond the Basics / Advanced Use

S-passive, blive-passive, and være-passive

Danish offers three related ways to shift attention away from the doer. They overlap, but their typical perspectives differ:

Pattern	Typical focus	Example	Natural interpretation
s-passive	rule, process, habit, general or formal presentation	Døren lukkes kl. 22.	The door is closed / closes at 10 p.m.
blive + past participle	event, action, or change	Døren blev lukket kl. 22.	The door was closed at 10 p.m.
være + past participle	state or result	Døren er lukket.	The door is closed.

A participle here is the verb form used after blive or være, such as lukket, solgt, or skrevet. The distinction is a tendency, not a mechanical one-to-one rule. Context, tense, verb meaning, and style all influence the choice. Still, the three-way contrast gives you a reliable first question: am I presenting a procedure, an event, or a resulting state?

Impersonal passives with der or det

The s-passive combines naturally with impersonal structures—sentences that do not identify a specific person as the doer:

• Der arbejdes på en løsning. — “Work is being done on a solution.”
• Der danses hele natten. — “There is dancing all night.”
• Det siges, at hun bor i Aarhus. — “It is said that she lives in Aarhus.”
• Det anbefales at bestille bord. — “Booking a table is recommended.”

These patterns are common in news, institutional writing, and polite recommendations. They also allow verbs without a normal direct object to appear in a passive-like impersonal construction, as in Der danses.

Verbs in -s that are not ordinary passives

Some verbs have an -s as part of their established meaning. Common examples include synes (“think/seem”), findes (“exist/be found”), lykkes (“succeed”), and trives (“thrive”). Other -s forms are reciprocal, meaning that participants act toward one another:

• Vi ses i morgen. — “See you tomorrow / We’ll see each other tomorrow.”
• De mødes hver uge. — “They meet every week.”
• Søstrene skændes ofte. — “The sisters often argue.”

Learning these as complete verbs or expressions prevents you from translating every final -s as English “be + participle.” Meaning and context matter as much as spelling.

Style and responsibility

Because a passive can omit the doer, it can make a statement sound neutral: Der blev begået fejl (“Mistakes were made”). That neutrality is useful when the actor is unknown, but it can also hide responsibility. In clear professional writing, ask whether the reader needs to know who must act. Ansøgningen sendes inden fredag gives a procedure; Du skal sende ansøgningen inden fredag gives the reader a direct instruction.

Practice Tips

1. Transform useful pairs. Start with five active present-tense sentences, identify what receives the action, and make it the passive subject: De kontrollerer billetterne → Billetterne kontrolleres. Say why omitting the doer makes sense.
2. Collect real examples by function. Photograph or note s-passives from Danish signs, websites, recipes, and forms. Label each one “rule,” “schedule,” “process,” or “general fact.” This trains meaning, not just endings.
3. Choose among three passives. For one verb such as lukke, practise Døren lukkes kl. 22, Døren blev lukket, and Døren er lukket. Explain aloud whether each sentence presents a routine, an event, or a state.
