Lesson 56

Perfekt with 'Sein' for Motion Verbs

Recommended resources

Guten Tag!

In our last lesson, you did an excellent job learning to construct sentences in the Perfekt tense using the auxiliary verb haben. You now have the most common tool for discussing the past in spoken German. Today, we'll complete your toolkit by focusing on the second auxiliary verb: sein (to be). While less common than haben, sein is essential for a specific but important group of verbs.

This lesson will teach you how to identify verbs that use sein and how to build sentences with them. By the end of our session, you'll be able to confidently decide whether to use haben or sein, allowing you to correctly describe any past action in German.

The "When": Identifying Verbs That Use sein

You'll be glad to know that the rule for using sein is quite logical. While haben is the default, sein is used in two main situations, plus for a few special verbs.

  1. Verbs of Motion: Verbs that describe a change of location from point A to point B. Think of traveling, walking, flying, or driving.
  2. Verbs of State Change: Verbs that describe a change in condition or state of being. Think of waking up, falling asleep, growing, or dying.
  3. A Few Special Verbs: The verbs sein (to be), bleiben (to stay), and werden (to become) always use sein in the Perfekt tense, even though they don't all fit neatly into the rules above.

A helpful way to remember the movement rule comes from the BBC's simple analogy: for verbs that describe movement into a location, you use bin (the ich form of sein). Think: "Rubbish must go into the bin."

To get a clear and detailed overview of these rules with plenty of examples, let's watch a video.

German Perfect Tense | SEIN or HABEN? Explained!

This video from "YourGermanTeacher" breaks down the rules for using sein into three distinct, easy-to-understand categories.

Please watch the following segments carefully: First, see the explanation for verbs of movement (change of place), like fliegen and fahren. Next, watch the section on verbs of state change, like wachsen and aufstehen. Finally, pay close attention to the four special verbs that always use sein: sein, werden, bleiben, and passieren.

The "Which": A List of Common sein Verbs

Now that you understand the rules, the most effective strategy is to memorize the most common verbs that partner with sein. Since they are a minority, learning them by heart is a manageable and very useful task.

The article below provides a fantastic, categorized list of these verbs.

The German Perfect Tense with Sein

This article from SmarterGerman takes a practical approach, suggesting that memorizing the sein verbs is the most efficient way to master them.

Please read the section Back to Shakespeare. Focus on the two main lists of verbs provided under the heading “List of Verbs that use “sein“ in Perfekt-Tense”. These are the key verbs you should start memorizing.

To summarize, here are the three categories again, with some key examples from the video and article:

  • Motion (A → B): gehen (to go), fahren (to drive), fliegen (to fly), kommen (to come), reisen (to travel), schwimmen (to swim).
  • State Change: aufwachen (to wake up), einschlafen (to fall asleep), wachsen (to grow), sterben (to die).
  • Special Verbs: sein (to be), bleiben (to stay), werden (to become), passieren (to happen).

The "How": Sentence Structure with sein

Here is the best news of the day: the sentence structure for the Perfekt with sein is exactly the same as with haben. You simply swap haben for the correctly conjugated form of sein. The past participle still goes to the very end of the sentence.

Subject + conjugated sein + ... (other information) ... + Partizip II.

This grammar chart provides a perfect visual comparison.

This chart clearly contrasts the Perfekt tense with 'haben' and 'sein'. On the left, you see the conjugation for a regular verb with 'haben' (ich habe gemacht). On the right, you see the conjugation for an irregular verb of motion with 'sein' (ich bin gefahren), illustrating the identical sentence structure but different auxiliary verb.

Let's quickly review the present tense conjugation of sein, as you'll need it for the Perfekt:

  • ich bin
  • du bist
  • er/sie/es ist
  • wir sind
  • ihr seid
  • sie/Sie sind

Let's Practice

Now, let's transform some present tense sentences into the Perfekt. Use your knowledge of the Partizip II and the rules for sein.

  1. Ich fahre nach Berlin. (to drive/travel)
    -> Ich _____ nach Berlin __________.
  2. Du stehst um 8 Uhr auf. (to get up)
    -> Du _____ um 8 Uhr ___________.
  3. Der Flug fliegt nach München. (to fly)
    -> Der Flug _____ nach München __________.
  4. Wir bleiben zu Hause. (to stay)
    -> Wir _____ zu Hause __________.
  5. Was passiert? (to happen)
    -> Was _____ __________?

Solutions:

  1. Ich bin nach Berlin gefahren.
  2. Du bist um 8 Uhr aufgestanden.
  3. Der Flug ist nach München geflogen.
  4. Wir sind zu Hause geblieben.
  5. Was ist passiert?

Sehr gut gemacht!

Conclusion

Congratulations! You have now mastered the complete structure of the German Perfekt tense. You can identify when to use haben and when to use sein, and you can construct sentences with both. This is a massive step in your ability to communicate about past events.

Key Takeaways:

  • The Perfekt tense uses the auxiliary verb sein for verbs of motion (A → B) and verbs of state change.
  • A few special verbs like bleiben, sein, werden, and passieren also always use sein.
  • The sentence structure is identical to using haben: the conjugated form of sein is in position 2, and the Partizip II is at the end.
  • For most verbs, you'll use haben. When in doubt, check if the verb involves movement or a change in condition.

In our next lesson, we will leave the past behind and look to the future. You will learn how to express your plans and intentions, a skill that will be vital for organizing your future life and studies in Germany or Austria.
