Past Tense: Perfekt
The main way to talk about the past in conversation is the Perfekt: 'Ich habe Pizza gegessen' (I ate pizza). The structure is similar to modal verbs: the auxiliary verb (haben or sein) is conjugated in the 2nd position, and the main verb goes to the very end in the Partizip II form.
