German conditional sentences with wenn: 5 rules & examples

German conditional sentences with wenn are used to express a condition that depends on a real or possible situation, typically following the pattern wenn + verb at the end (if …). This article explains the five core rules, shows 20 ready‑to‑use examples, and tells you how to practise them efficiently.

What are German conditional sentences with wenn?

A conditional sentence with wenn consists of two clauses: a condition (the "wenn‑clause") and a result (the main clause). The verb in the "wenn" clause goes to the end, while the main clause follows normal word order.

Example: Wenn ich morgen früh aufstehe (If I get up early tomorrow), koche ich Frühstück (I will cook breakfast).

These structures are common in everyday conversation, emails, and exams. For extra practice you can browse everyday phrases that include conditional forms.

When should I use wenn versus falls?

Both wenn and falls translate to "if", but falls adds a slight nuance of uncertainty, similar to "in case". Use wenn for conditions you consider likely or neutral.

Example: Falls es regnet (In case it rains) suggests you are not sure about the rain, whereas Wenn es regnet (If it rains) treats the rain as a normal possibility.

Try the writing prompts tool to create sentences that compare both conjunctions.

What are the five rules for building conditional sentences with wenn?

1. Place the verb at the end of the wenn‑clause. Example: Wenn du kommst (If you come).
2. Use present tense for future conditions. Example: Wenn ich spare, kaufe ich ein Auto (If I save, I will buy a car).
3. Keep the main clause in the appropriate tense. Present for general truths, future or modal for future actions. Example: Wenn er arbeitet, verdient er Geld (If he works, he earns money).
4. Separate the clauses with a comma. German punctuation requires a comma before the main clause. Example: Wenn das Wetter schön ist, gehen wir spazieren (If the weather is nice, we go for a walk).
5. Avoid double subjects. The subject appears only once per clause. Example: Incorrect: Wenn ich ich gehe; Correct: Wenn ich gehe.

These five rules cover the most common pitfalls. To hear the correct intonation, use the listen‑and‑repeat tool with the example sentences below.

FAQ

Can I use the past tense in a wenn‑clause?

Yes. For unreal past conditions you use the subjunctive II (Konjunktiv II), e.g., Wenn ich mehr Geld gehabt hätte (If I had had more money).

Do I need a comma before the main clause?

German grammar requires a comma separating the wenn‑clause from the main clause, even if the main clause comes first.

Is it correct to say "wenn du willst" for "if you want"?

Absolutely. Wenn du willst (If you want) is a common, informal way to offer a choice.

How many times should I repeat a conditional sentence to master it?

Three spaced repetitions are enough for short‑term memory; using the repeat tool daily for a week solidifies long‑term retention.
