The German Past Tense

Knowing how to form the two common German past tenses, the simple past and conversational past, is key to becoming a better German speaker and achieving fluency.

Your days of speaking only about the present are over. Get ready to get a little nostalgic—we’re looking back to the past.


Why Learn the German Past Tense?

There are plenty of good reasons to learn how to conjugate verbs in the past tense. Learning the past tense is a critical step toward overall German fluency. The more verb tenses you know, the more things you can express in German. When you interact with other German speakers on a daily basis, the ability to manipulate verbs is crucial to successful communication.

More specifically, knowing how to conjugate verbs in the German past tense will allow you to tell (and listen to) stories about what has already happened. Lots of simple German conversations involve the past tense, such as telling your roommate how your day was, asking a new friend about her childhood or fielding questions about past experience in a job interview. You’ll have better, deeper conversations with German speakers if you aren’t limited to the present tense.

So, what are the key differences between the simple past and conversational past tenses? Let’s take a deeper look.

Conjugating in the Simple Past

In German, the simple past is used mostly for writing and storytelling. You might have also heard this tense called the Imperfekt (imperfect) or Präteritum (preterite).

You’ll find that most German books are written in the simple past tense. This can be confusing if you’re still new to German because you may not recognize many of the verb conjugations at first. But now that you know what to look for, you’ll find that books can be a great resource for practicing the simple past.

Conjugating in the simple past follows different rules for weak verbs (which don’t change their stem) and strong verbs (which do change their stem).

Conjugating Weak Verbs

The first thing you’ll have to do when conjugating a weak verb is identify its stem.

Let’s take a look at the weak verb lernen (to learn).

First, locate your stem, which in this case is lern-.

Then you’ll take that stem and add on a new verb ending based on the conjugation rules.

Lernen ConjugationEnglish TranslationSagen ConjugationEnglish Translation
ich lernte I learned ich sagte I said
du lerntest You learned du sagtest You said
er/sie/es lernte He/she/it learned er/sie/es sagte He/she/it said
wir lernten We learned wir sagten We said
ihr lerntet You learned ihr sagtet You said
Sie/sie lernten You/they learned Sie/sie sagten You/they said

These simple steps and verb endings apply to any regular verb.

Let’s look at how conjugations work in the context:

Er sagte, dass er ein Arzt ist. (He said that he is a doctor.)

Conjugating Strong Verbs

Strong verbs, on the other hand, undergo a stem change when conjugating so you’ll just have to memorize them. 

Let’s look at the strong verbs werden  (to become) and bleiben  (to stay), for example:

Werden ConjugationEnglish TranslationBleiben ConjugationEnglish Translation
ich wurde I became ich blieb I stayed
du wurdest You became du bliebst You stayed
er/sie/es wurde He/she/it became er/sie/ese blieb He/she/it stayed
wir wurden We became wir blieben We stayed
ihr wurdet You became ihr bliebt You stayed
Sie/sie wurden You/they became Sie/sie blieben You/they stayed

Let’s consider an example sentence with another strong verb, such as lesen (to read). This verb uses las as its stem.

Welches Buch liest du? (Which book are you reading?)

Even though our guide above suggests we’d use –test as the du ending, lesen loses the first “t” in the ending. Therefore we’ve got las + -est, which gives us lasest.

Welches Buch lasest du? (Which book did you read?)

As you can see, most of the time you’ll need to memorize just the endings for weak verbs but entire new verb forms when it comes to strong verbs.

Conjugating in the Conversational Past

The conversational past, also known as the present perfect or Perfekt  tense, is used in everyday conversations to describe an action that has been completed.

In German, as in English, there is also the past perfect tense known as the Plusquamperfekt . It’s used when speaking about past actions in past simple or present perfect, but for describing something that happened even before that. 

The conversational past is comprised of two components. The first component is the helping verb, and the second is the past participle.

Helping Verbs: Choosing Between Haben and Sein

We’re going to start with the helping verb first. In German, there are two to choose from: haben (“to have”) or sein (“to be”). 

Here’re their conjugations:

Haben ConjugationEnglish TranslationSein ConjugationEnglish Translation
ich habe I have ich bin I am
du hast You have du bist You are
er/sie/es hat He/she/it has er/sie/es ist He/she/it is
wir haben We have wir sind We are
ihr habt You (plural) are ihr seit You (plural) are
Sie/sie haben They/you (formal) are Sie/sie sind They/you (formal) are

You’ll want to memorize which helping verbs go with which past participles. An easy trick to differentiating between haben and sein lies in the meaning of the main verb.

If the main verb describes movement, use sein. If not, use haben.

Forming the Past Participle

Once you’ve identified and conjugated your helping verb, you’ll need to add a past participle. Weak verbs will use the following formula for the past participle:

ge + verb stem + t

Let’s get into some examples for context:

Ich lebe für die Schokolade. (I live for the chocolate.)

Since leben , or “to live,” is a weak verb, we can go by the formulation above. Taking leb from the infinitive, we’ve got ge + leb + t, which results in gelebt.

Now that we’ve got the past participle, let’s consider the helping verb. Since leben doesn’t show movement, we’ll use haben.

Conjugate haben for ich (I) and you end up with:

Ich habe für die Schokolade gelebt. (I lived for the chocolate.)

Strong verbs, on the other hand, will often discard the “ge,” the “t” or both to form a unique past participle all their own.

Let’s use fliegen , a strong verb which means “to fly.”

Wohin fliegen sie nächste Woche? (Where are they flying to next week?)

The good news is that fliegen keeps the ge prefix. The bad news is that it decides what it wants after that. The past participle of fliegen is geflogen, and since we have to move in order to fly, sein is our helping verb.

Do a simple conjugation of sein for sie (they) and you’ve got:

Wohin sind sie letzte Woche geflogen? (Where did they fly to last week?)

As you can see, strong verbs take their own forms when it comes to past participles.

A Note on Modal Verbs in the Conversational Past Tense

Speaking of their own forms, modal verbs (such as can, might and should) are particularly tricky when it comes to the conversational past tense. They use what’s called a double infinitive structure.

Basically, if the only verb in the sentence is the modal, you’ll use haben and the weak verb conjugation rules we described above.

However, if there’s another verb in addition to the modal, you’ll use two infinitives at the end of the sentence rather than the past participle.

Hence the double infinitive name. Confused? Don’t worry. We’ve got you covered.
