Exercise 2: Multiple Choice

1.
This is the present tense form, not the simple past.
Wrong stem form; 'kommen' in the simple past is 'kam', not 'komte'.
2.
Wrong form; 'helfen' in the simple past is 'half', not 'halfte'.
Wrong past form; 'geholfen' is the past participle, not the simple past.
3.
This form 'riefte' does not exist in the simple past.
Wrong stem form; correct is 'rief', not 'ruffte'.
4.
Wrong form; 'wart' is 2nd person singular, not for 'we'.
Wrong form; for 'we' you need 'waren', not 'war'.

Understanding the Präteritum: Irregular Verbs

This lesson focuses on the Präteritum (simple past tense) in German, specifically on irregular verbs. Unlike regular verbs, irregular verbs often change their stem vowel when conjugated in the past tense. This means you usually need to memorize these forms as they do not follow a simple pattern.

Key Concepts

  • Präteritum: Used mostly in written language and storytelling to describe actions completed in the past.
  • Irregular verbs: These verbs change their stem in the Präteritum, requiring special attention.

Important Examples

Here are some common irregular verbs and their Präteritum forms:

ichduer/sie/eswirihrsie/Sie
war (sein)warstwarwarenwartwaren
kam (kommen)kamstkamkamenkamtkamen
rief (rufen)riefstriefriefenrieftriefen
half (helfen)halfsthalfhalfenhalfthalfen

Memorization Tips

Because these verbs do not follow a fixed pattern, memorization is essential. Notice how the stem vowel changes (e.g., “kommen” becomes “kam”). This change is crucial to master correct usage.

Useful Notes on Language Differences

In English, past tense for irregular verbs often changes the entire verb or its spelling (e.g., “come” → “came”), which is similar in German but usually limited to the verb stem vowel. The German Präteritum is primarily used in written form or formal speech, whereas in English, the simple past is frequently used in daily conversation.

Here are some helpful German words and their English equivalents to keep in mind:

  • sein (to be) → war (was/were)
  • kommen (to come) → kam (came)
  • rufen (to call) → rief (called)
  • helfen (to help) → half (helped)
