Explanation
What is the Perfekt?
The Perfekt (Perfect Tense) is the most common way to talk about the past in spoken German. While English distinguishes between "I did" and "I have done," German speakers use the Perfekt for both situations in daily conversation. It describes actions that are completed.
Sentence Structure
The Perfekt is a compound tense, meaning it consists of two parts: a conjugated auxiliary verb (haben or sein) and the Partizip II (Past Participle). The conjugated verb stays in the second position of the sentence, while the Partizip II always moves to the very end.
Haben or Sein?
Most German verbs use haben as the auxiliary verb. However, you must use sein if the verb indicates a movement from one place to another (like gehen - to go) or a change of state. Learning which verbs use sein is a key part of mastering the Perfekt at the A1 level.
Forming the Partizip II
For regular (weak) verbs, the Partizip II is usually formed by adding the prefix ge- and the suffix -t to the verb stem (e.g., machen becomes gemacht). Irregular (strong) verbs often end in -en and may change their stem vowel (e.g., gehen becomes gegangen). Verbs ending in "-ieren," like studieren, do not take the "ge-" prefix.

Common Mistakes
The verb 'gehen' implies movement from A to B, so it must use 'sein' instead of 'haben'.
In German, the Partizip II (gemacht) must always be placed at the very end of the sentence.
Wait, this is correct! A common mistake is saying 'gevergessen'. Verbs with inseparable prefixes like 'ver-' do not add 'ge-'.
