Perfekt vs. Präteritum: Which German Past Tense to Use
Both describe the past. Use the Perfekt (“Ich habe gegessen”) in everyday speech and informal writing; use the Präteritum (“Ich aß”) in written narration, news, and books. The big exceptions are sein, haben, and the modal verbs, whose Präteritum (war, hatte, konnte) is normal even when speaking.
German has two main ways to talk about the past, and the choice is mostly about register — spoken versus written — not about meaning. In most cases they translate to the same English sentence.
The Perfekt is a compound tense: a conjugated form of haben or sein plus the past participle at the end. “Ich habe einen Brief geschrieben” (I wrote / have written a letter). It is the default in conversation across Germany and Austria.
The Präteritum (also called the simple past or Imperfekt) is a single conjugated verb: “Ich schrieb einen Brief.” You will meet it constantly when reading — newspapers, novels, reports — but it sounds formal in casual speech.
The practical shortcut: speak in the Perfekt, write narration in the Präteritum, and always use the Präteritum of sein (war), haben (hatte), and the modal verbs (konnte, musste, wollte) even when speaking, because the Perfekt of those sounds clumsy.

Examples
Common mistakes
- Using sein vs. haben incorrectly in the Perfekt. Verbs of motion or change of state take sein (ist gegangen, ist aufgewacht); most others take haben.
- Forgetting to send the past participle to the end of the clause: “Ich habe gegessen einen Apfel” is wrong — it is “Ich habe einen Apfel gegessen”.
- Saying “Ich habe gewesen” in conversation. Use the Präteritum: “Ich war”.
- Over-using the Präteritum in speech, which makes you sound like a written report rather than a person talking.
FAQ
Is the Perfekt or the Präteritum more correct?
Neither is more correct — they belong to different registers. The Perfekt is standard in spoken German and informal text; the Präteritum is standard in written narration. Both are fully grammatical.
Which verbs use the Präteritum even when speaking?
sein (war), haben (hatte), and the modal verbs (konnte, musste, durfte, sollte, wollte). Their Perfekt forms sound awkward, so Germans use the Präteritum for them in everyday speech.
Does the choice change the meaning?
Usually not. “Ich habe gegessen” and “Ich aß” both mean “I ate.” The difference is style and context, not time or aspect, in the vast majority of sentences.
