The German Past Conditional: hätte / wäre + Partizip Perfekt

The German past conditional (Konjunktiv II Vergangenheit) describes something that would have happened differently in the past, but did not happen that way. In English, it is usually expressed with “would have”.

• I would have studied.
• I would have gone.
• I would have helped.

How to form the past conditional

The structure always has two parts:

1. hätte or wäre, the Konjunktiv II form of the auxiliary verb
2. Partizip Perfekt, the past participle

Formula: hätte / wäre + Partizip Perfekt

When to use hätte and wäre

• hätte is used when the verb takes haben in the Perfekt. This applies to most verbs.
• wäre is used when the verb takes sein in the Perfekt, including verbs describing movement or a change of state, such as gehen, fahren, sterben and bleiben.

Examples:

• Ich hätte gelernt. – I would have studied. (with haben)
• Ich wäre nach Hause gegangen. – I would have gone home. (with sein)

Simple example sentences

• Ich hätte das Buch gelesen. – I would have read the book.
• Er wäre gestern gekommen. – He would have come yesterday.
• Wir hätten mehr Zeit gebraucht. – We would have needed more time.
• Sie wäre gern mitgefahren. – She would have liked to come along.
• Ich hätte dir geholfen. – I would have helped you.

Negative sentences

To make the sentence negative, place nicht before the Partizip Perfekt.

• Ich hätte nicht gearbeitet. – I would not have worked.
• Er wäre nicht geblieben. – He would not have stayed.

Questions

In a question, the auxiliary verb comes first.

• Hättest du das gemacht? – Would you have done that?
• Wärst du gestern gekommen? – Would you have come yesterday?

Practice examples

Important distinction

The past conditional always describes something contrary to reality: an event that did not happen, but could have happened differently.

This distinguishes it from the present conditional, or Konjunktiv II Präsens:

• ich würde lernen – I would study
• ich hätte gelernt – I would have studied
