Simple past: irregular verbs (war, kam, rief, half)

Präteritum: unregelmäßige Verben (war, kam, rief, half)


Unregelmäßige Formen im Präteritum müssen meistens einfach auswendig gelernt werden.

(Irregular forms in the simple past usually just have to be memorized.)

What you are learning here: Präteritum (simple past) for irregular verbs

In German, many common verbs form the simple past (Präteritum) with a new stem.

This is especially frequent in written German and in short narratives (reports, emails, news, stories).

  • sein → war / warst / waren …
  • kommen → kam / kamst / kamen …
  • rufen → rief / riefst / riefen …
  • helfen → half / halfst / halfen …

The key idea: the stem changes (you cannot “-te” these verbs)

Many learners try to build the past with -te (like machte).

For these verbs, that is wrong.

  • rufen: ich rufteich rief
  • kommen: ich kommteich kam
  • helfen: ich helft(e)ich half
  • sein: ich seiteich war

A practical pattern: endings look familiar

Even though the stem changes, the endings are quite regular.

Person Typical Präteritum ending Example (kommen)
ich (no ending) ich kam
du -st du kamst
er/sie/es (no ending) er kam
wir -en wir kamen
ihr -t ihr kamt
sie/Sie -en sie kamen

Good news: If you know wir -en and ihr -t, you can form many lines in the table quickly.

Don’t mix up Präteritum and Konjunktiv II (a common confusion)

These forms can look similar, but the meaning is different.

Form German Meaning
Präteritum Ich war im Büro. Past fact: “I was (yesterday).”
Konjunktiv II Ich wäre im Büro. Hypothetical: “I would be …”
  • In your exercises you need the past fact forms: war, kam, rief, half.

How to use Präteritum naturally (A2 focus)

In everyday spoken German, people often use Perfekt (“ich habe … gemacht”).

But sein is very common in Präteritum in speech, and Präteritum is common in:

  • short reports: Gestern war viel los.
  • emails/notes: Ich rief dich an, aber du warst nicht da.
  • narratives: Der Krankenwagen kam schnell.

Self-check: 3 quick questions before you submit an answer

  1. Time signal? Words like gestern, letzte Woche → you likely need past.
  2. Is the verb one of the four here? If yes: use the table form (not -te).
  3. Correct person? Match the subject: wir-en, ihr-t, du-st.

Mini examples you can copy as models

  • sein: Gestern waren wir im Büro.
  • kommen: Der Notarzt kam sofort.
  • rufen: Ich rief den Kollegen an.
  • helfen: Wir halfen der neuen Nachbarin beim Umzug.
  1. Irregular verbs in the simple past almost always change the verb stem.
Person (person)sein (to be)kommen (to come)rufen (to call)helfen (to help)
ich (I)war (was)kam (came)rief (called)half (helped)
du (you)warst (were)kamst (came)riefst (called)halfst (helped)
er/sie/es (he/she/it)war (was)kam (came)rief (called)half (helped)
wir (we)waren (were)kamen (came)riefen (called)halfen (helped)
ihr (you (plural))wart (were)kamt (came)rieft (called)halft (helped)
sie/Sie (they/you (formal))waren (were)kamen (came)riefen (called)halfen (helped)

Exercise 1: Multiple choice

Instruction: Choose the correct answer

1. Gestern ___ ich in der Notaufnahme, weil ich starke Schmerzen hatte.

Yesterday I ___ in the emergency room because I was in severe pain.

2. Als der Krankenwagen ___, rief die Nachbarin sofort den Notruf.

When the ambulance ___, the neighbor immediately called emergency services.

3. Der Notarzt ___ mich zurück und stellte noch zwei Fragen.

The emergency doctor ___ me back and asked two more questions.

4. Im Treppenhaus ___ wir dem Mann, bis die Feuerwehr da war.

In the stairwell we ___ the man until the fire department was there.

Exercise 2: Multiple Choice

Instruction: Choose the correct sentence in the simple past.

1.
“wäre” is subjunctive II, not simple past; the correct form is “war”.
This is present tense (“bin”) instead of simple past; correct would be “ich war”.
2.
Mixes present/perfect; for a narrative in the past you need simple past: “kam” and “half”.
“kamm” contains a double consonant – the correct form is “kam” (irregular).

Exercise 3: Rewrite the phrases

Instruction: Write the sentences in the simple past and insert the correct form of sein, kommen, rufen or helfen (Example: Wir sind im Büro. → Wir waren im Büro.).
