Perfekt vs Präteritum

German has two main past tenses — the Perfekt and the Präteritum — and knowing when to use each one is essential for sounding natural. This lesson explains the differences, the rules of thumb, and the exceptions.

The Core Difference

Feature	Perfekt	Präteritum
Structure	Compound (auxiliary + participle)	Simple (one verb form)
Example	Ich habe das Buch gelesen.	Ich las das Buch.
Primary use	Spoken German	Written German
Feel	Conversational, informal	Narrative, formal, literary

Both translate the same way into English: "I read the book" or "I have read the book."

Rule 1: Spoken German Uses the Perfekt

In everyday conversation, Germans almost always use the Perfekt:

• Was hast du gestern gemacht? — What did you do yesterday?
• Ich habe einen Film gesehen. — I watched a film.
• Wir sind ins Restaurant gegangen. — We went to a restaurant.

If you used the Präteritum in casual speech (except for haben, sein, and modals), you would sound overly formal or literary, as if you were narrating a novel.
