What is Present Perfect (Perfekt)?

The present perfect (Perfekt) is the most common way Germans talk about the past. It combines the auxiliary verbs haben or sein with a past participle to express completed actions. Learning when to use haben versus sein is key to mastering this tense.

Short answer

Present perfect uses haben or sein + past participle: Ich habe ein Buch gelesen (I have read a book) or Ich bin nach Berlin gefahren (I went to Berlin). Use haben for most transitive verbs, sein for motion and state change.
