Hi friends! Today we'll learn how to form the Perfekt past tense in German, which is crucial for everyday conversations to say 'what you did'. For most verbs, we use haben (to have) as the auxiliary verb. For example, Ich habe Pizza gegessen. (I ate pizza.) Here, gegessen describes the eating action. However, for verbs indicating movement or a change of state, we use sein (to be) as the auxiliary. For instance, Ich bin nach Hause gegangen. (I went home.) or Ich bin eingeschlafen. (I fell asleep.) Remember, in both cases, the main verb is always in its Partizip II form (past participle). With practice, you'll quickly identify which auxiliary verb to use!
