Active vs Passive: What Changes?

Active vs passive focus: Akk → Nom subject, werden + Partizip II frame, omit/name agent, dative stays, modals preview, process vs state, mistakes.

1.The central difference: what is in focus?

Active and passive describe the same event from different viewpoints. In an active sentence the centre is usually the person or thing that performs the action. In a passive sentence the action itself, or the person/thing affected by it, becomes more important.

Der Mechaniker repariert das Auto.
Das Auto wird repariert.
Die Firma baut ein neues Haus.
Ein neues Haus wird gebaut.

At A2 the point is not only to “change the verb”, but to see the change of roles: a typical accusative object from the active sentence becomes the grammatical subject of the passive.

2.Roles in one event

A useful model is: actor → action → affected object.

Die Ärztin untersucht den Patienten.
  • die Ärztin — actor and nominative subject;
  • untersucht — action;
  • den Patienten — accusative object.

This scheme is the starting point for the basic personal passive.

3.Basic active pattern

A very common active pattern is: nominative subject + finite verb + accusative object.

Der Koch bereitet das Essen vor.
Die Mitarbeiterin beantwortet die E-Mail.

The subject controls the finite verb and shows who performs the action.

4.Basic passive pattern

The matching Passiv Präsens pattern is: new nominative subject + werden + … + Partizip II.

Das Essen wird vorbereitet.
Die E-Mail wird beantwortet.

At A2 this is the central passive model.

5.What changes from active to passive?

Der Mechaniker repariert das Auto.
Das Auto wird repariert.

Three important things happen:

  1. das Auto moves from accusative object to nominative subject;
  2. the finite verb becomes a form of werden;
  3. the lexical verb appears as Partizip II: repariert.

The original actor can be left out if it is not important.

6.The accusative object becomes the subject

The main transformation for the basic personal passive is: accusative object → nominative subject.

Die Polizei kontrolliert den Fahrer.
Der Fahrer wird kontrolliert.
Die Firma liefert die Pakete.
Die Pakete werden geliefert.

Because the noun phrase now has subject role, its case also changes.

7.Article forms can change visibly

With masculine nouns the change is especially clear: den Patienten (accusative in active) → der Patient (nominative in passive).

Die Ärztin untersucht den Patienten.
Der Patient wird untersucht.

With feminine, neuter and plural nouns the article form may look the same even though the grammatical role has already changed.

Der Techniker repariert die Maschine.
Die Maschine wird repariert.

8.The old subject is no longer the subject

In the active sentence die Technikerin is the nominative subject. In the passive the subject is das Programm; the original actor is no longer a required part of the sentence.

Die Technikerin installiert das Programm.
Das Programm wird installiert.

9.The actor can be omitted

The passive is especially useful when the actor is unknown, obvious or unimportant. The centre is what happens, not who does it.

Die Straße wird repariert.
Die Rechnung wird morgen bezahlt.
Die Fenster werden jeden Abend geschlossen.

10.The actor can still be named

If the actor matters, it is often added with von + dative. The von phrase is not the subject.

Das Auto wird von einem Mechaniker repariert.
Der Patient wird von der Ärztin untersucht.

11.werden is the finite verb

In Passiv Präsens it is werden that marks person and number. Partizip II does not change.

Person / numberForm of werden
ichwerde
duwirst
er / sie / eswird
wirwerden
ihrwerdet
sie / Siewerden

The passive is very often used in the third person singular or plural.

Der Brief wird geschrieben.
Die Briefe werden geschrieben.

12.The new subject controls werden

Only the finite form of werden changes; it agrees with the new subject.

Das Paket wird geliefert.
Die Pakete werden geliefert.
Der Termin wird verschoben.
Die Termine werden verschoben.

13.Partizip II carries the lexical action

The passive combines werden with the Partizip II of the lexical verb. The rules for forming Partizip II are already familiar from the past-tense system.

InfinitivePartizip II
reparierenrepariert
machengemacht
öffnengeöffnet
schreibengeschrieben
bauengebaut
Die Tür wird geöffnet.
Der Bericht wird geschrieben.
Das Haus wird gebaut.

14.The passive forms a verbal bracket

In a normal main clause the finite form of werden stands in position 2 and Partizip II stands near the end. This is another instance of the German verbal bracket.

Position 1Verb 2Middle fieldPartizip II
Das Autowirdheuterepariert.
Die Paketewerdenam Montaggeliefert.
Der Raumwirdjeden Morgengereinigt.
Das Auto wird heute repariert.
Die Pakete werden am Montag geliefert.
Der Raum wird jeden Morgen gereinigt.

15.Time or place can come first

In the passive the usual main-clause rule remains: the finite verb stays in position 2. A time or place phrase and the new subject cannot both stand before the finite verb.

Heute wird das Auto repariert.
Im Büro werden die Computer kontrolliert.
Am Montag wird die Bestellung verschickt.

16.Questions in the passive

In a yes/no question the form of werden moves to first position. In a wh-question the question word comes first and werden second. Partizip II stays at the end of the verbal bracket.

Wird das Auto heute repariert?
Werden die Pakete morgen geliefert?
Wann wird das Auto repariert?
Wo werden die Pakete gelagert?

17.Negation with nicht

nicht can negate the passive action as a whole or a specific part of the sentence. The basic frame stays the same: wird … nicht … repariert.

Das Auto wird heute nicht repariert.
Die Pakete werden nicht am Montag geliefert, sondern am Dienstag.

18.Negation with kein

When an indefinite noun phrase is negated, kein works as usual. The choice between nicht and kein follows the same logic as in active sentences.

Es wird kein neues Büro gebaut.
Heute werden keine Pakete geliefert.

19.Why speakers use the passive

The passive is useful when the process or the affected object matters more than the actor. Typical contexts include:

  • work and production processes;
  • repairs and services;
  • official information;
  • instructions and procedures;
  • news and announcements;
  • describing what happens to a thing or person.
Die Bestellung wird bearbeitet.
Die Straße wird gesperrt.
Das Formular wird geprüft.

20.Unknown actor

Sometimes it really is unknown who performed the action. Then the event itself stays in focus.

Mein Fahrrad wurde gestohlen.

The form here is already past, but the communicative reason for the passive is the same: the event is known, the actor is not.

21.Obvious or institutionally clear actor

Sometimes it is clear which service or group of people performs the action. Exactly which employee does it is often irrelevant to the message.

Im Krankenhaus wird der Patient untersucht.
Im Hotel werden die Zimmer jeden Tag gereinigt.

22.Active and passive do not always sound equally natural

Both forms can be grammatically possible while putting different information in the centre. That is a difference of information focus, not of the event itself.

Die Mitarbeiterin bearbeitet Ihre Anfrage.
Ihre Anfrage wird bearbeitet.

Active highlights the employee. Passive highlights the request and the process of handling it.

23.Not every verb gives the same basic pattern

The simplest A2 passive pattern comes from verbs with an accusative object.

Jemand öffnet die Tür.
Die Tür wird geöffnet.

If a verb has no accusative object, there may be no phrase that can simply become a new nominative subject. In Die Kinder helfen dem Mann., for example, dem Mann is dative and does not automatically become der Mann in a basic transformation.

24.Dative objects stay dative

An important structural rule: a dative object is not the new nominative subject. The second sentence below is an impersonal passive; it shows that dem Patienten remains dative.

Die Ärztin hilft dem Patienten.
Dem Patienten wird geholfen.

25.Passive with two objects

If the active sentence has both a dative and an accusative object, the accusative object becomes the passive subject and the dative stays dative.

Die Firma schickt dem Kunden die Rechnung.
Die Rechnung wird dem Kunden geschickt.
  • die Rechnung: accusative → nominative;
  • dem Kunden: dative → remains dative.

This links the passive directly to the case system.

26.Passive with modal verbs

The passive can combine with modal verbs. At A2 it is enough to recognise the pattern: modal verb + … + Partizip II + werden. The modal is finite; the passive infinitive werden stands at the end with Partizip II.

Die Rechnung muss heute bezahlt werden.
Die Tür kann geöffnet werden.

27.Do not confuse process and state

wird geöffnet describes a process: the door is being opened. ist geöffnet describes a state/result: the door is open. Basic A2 passive is mainly the process passive with werden.

Die Tür wird geöffnet.
Die Tür ist geöffnet.

28.Common mistakes

Old accusative form kept

Incorrect: Den Patient wird untersucht. Correct: the new subject must be nominative.

Der Patient wird untersucht.

sein instead of werden for a process

If the meaning is an action or process, the form with werden is needed. Die Tür ist geöffnet has a different meaning and describes a state.

Die Tür wird geöffnet.

Missing Partizip II

Incorrect: Das Auto wird reparieren. Correct — with Partizip II.

Das Auto wird repariert.

Original actor wrongly kept as subject

Incorrect transformation logic: Der Mechaniker wird das Auto repariert. In a simple passive the affected object becomes the subject.

Das Auto wird repariert.

29.A practical analysis method

When reading an active/passive pair, it helps to work step by step:

  1. Find the finite verb.
  2. In the active sentence, identify the subject: who performs the action?
  3. Find the accusative object: who or what is affected?
  4. In the passive, check which phrase is now nominative.
  5. Find the finite form of werden.
  6. Find Partizip II at the end of the frame.
  7. Ask: what does the speaker want to put in the centre of the message?

This method combines word order, case and meaning. The core contrast remains the same:

Der Mechaniker repariert das Auto.
Das Auto wird repariert.
