Perfect Tense (das Perfekt): Examples in Detail

haben or sein? Cases, structure & full sentence analysis

In Part 1 we learned the basic formula of the Perfect tense and the rules for choosing haben or sein.
In this lesson we put those rules into practice. We will analyse the six example sentences from the whiteboard one by one – looking carefully at the cases, the helping verb, and the Partizip II.


Quick Reminder (from Part 1)

The structure of the Perfect tense is always the same:

Subject + haben/sein + Object / Adverb + Partizip II

  • Use haben with reflexive verbs and with verbs that take an accusative object.
  • Use sein with verbs of movement, change of state, and a few special verbs (sein, bleiben, passieren).

The Partizip II always stands at the end of the sentence.


Example 1 – HABEN

Present: Ich lese die Zeitung.
Perfect: Ich habe die Zeitung gelesen.

Why haben? Because lesen takes a direct object – die Zeitung. Verbs with an accusative object use haben.

  • Subject: Ich (Nominative)
  • Helping verb: habe (haben conjugated for ich)
  • Object: die Zeitung (Accusative)
  • Partizip II: gelesen (perfect form of lesen)

Everything follows the rule: subject, helping verb, object, Partizip II.


Example 2 – HABEN

Present: Lisa studiert Informatik.
Perfect: Lisa hat Informatik studiert.

  • Subject: Lisa (Nominative)
  • Helping verb: hat (haben for sie)
  • Object: Informatik (Accusative)
  • Partizip II: studiert

Again there is an accusative object, so we use haben.


Example 3 – HABEN

Present: Er versteht den Mietvertrag.
Perfect: Er hat den Mietvertrag verstanden.

Look carefully at the object: den Mietvertrag.

  • The nominative form would be der Mietvertrag.
  • Here it is the direct object, so it changes to den – the accusative form.

Because there is a clear accusative object, we must use haben.

  • Subject: Er (Nominative)
  • Helping verb: hat
  • Partizip II: verstanden

Example 4 – SEIN (Movement)

Present: Paul kommt um 8 Uhr.
Perfect: Paul ist um 8 Uhr gekommen.

Why sein? Because kommen is a verb of movement – from one place to another. Movement verbs take sein.

  • Subject: Paul (Nominative)
  • Helping verb: ist (sein for er)
  • Time: um 8 Uhr
  • Partizip II: gekommen

There is no accusative object here.


Example 5 – SEIN (Movement)

Present: Wir fahren nach Berlin.
Perfect: Wir sind nach Berlin gefahren.

  • Subject: Wir (Nominative plural)
  • Helping verb: sind (sein for wir)
  • Direction: nach Berlin
  • Partizip II: gefahren

fahren shows movement from A to B, so sein is required.


Example 6 – SEIN (Special verb)

Present: Im Winter passieren viele Unfälle.
Perfect: Im Winter sind viele Unfälle passiert.

passieren belongs to the small group of special verbs that always take sein (together with geschehen, sein, bleiben).

  • Subject: viele Unfälle (Nominative)
  • Helping verb: sind
  • Time: Im Winter
  • Partizip II: passiert

Cases Used in These Examples

In every sentence the subject is in the Nominative case:
Ich, Lisa, Er, Paul, Wir, viele Unfälle.

In the three haben examples we also have an Accusative object:
die Zeitung, Informatik, den Mietvertrag.

Simple rule to remember:

  • When you see an accusative object → use haben.
  • When the verb shows movement or is a special verb like passieren → use sein.

All Six Perfect Sentences at a Glance

  1. Ich habe die Zeitung gelesen.
  2. Lisa hat Informatik studiert.
  3. Er hat den Mietvertrag verstanden.
  4. Paul ist um 8 Uhr gekommen.
  5. Wir sind nach Berlin gefahren.
  6. Im Winter sind viele Unfälle passiert.

Practice Tip

For every new verb you learn, always write down two things:

  1. The Partizip II
  2. Whether it takes haben or sein

Then build your own sentences using the same pattern you saw in the six examples above.
