What are Simple Past Irregular Verbs?
Irregular verbs in the simple past (Präteritum) do not follow the standard -te pattern. Instead, they change the verb stem vowel and add simple personal endings. Common irregular verbs like sein, haben, gehen, and kommen must be memorized.
Irregular past tense verbs change the stem vowel (e.g., singen → sang) and add personal endings directly: ich sang, du sangst, er/sie/es sang, wir sangen, ihr sangt, sie/Sie sangen. Memorize the stem change for each irregular verb.
- •sein → war
- •haben → hatte
- •gehen → ging
- •kommen → kam
- •ich sang
- •du sangst
- •er/sie/es sang
- •wir/sie/Sie sangen, ihr sangt
