German: Expressing 'Unless' with 'wenn ... nicht' and 'es sei denn'
Learn to express negative conditions in German: 'I won't go unless you come' becomes 'Ich gehe nicht, wenn du nicht kommst' or 'Ich gehe nicht, es sei denn, du kommst.'
By TheaFirst conversations · Yapr Learn
In English, 'unless' means 'if not'. German has no single everyday word that works exactly like English 'unless'. Instead, elementary German uses a normal wenn-clause with nicht: 'Ich gehe nicht, wenn du nicht kommst.' A more formal alternative is 'es sei denn', which introduces an exception. This lesson teaches both patterns so you can state negative conditions clearly.
By the end, you can…
- express 'unless' using a wenn-clause with nicht.
- use 'es sei denn' to introduce an exception.
- choose between the everyday and formal patterns.
Listen once. Try it slowly. Then say it without looking.

Ich gehe nicht, wenn du nicht kommst.
I won't go unless you come.
ikh GAY-uh nikht, ven doo nikht KOMST
Everyday spoken German. The wenn-clause carries the negative condition.
Wir fahren nicht los, wenn es nicht aufhört zu regnen.
We won't set off unless it stops raining.
veer FAH-ruhn nikht lohs, ven es nikht OWF-hurt tsoo RAYG-nuhn
Useful for weather and travel plans. Note the separable verb losfahren.
Ich komme nicht mit, es sei denn, du fragst mich.
I won't come along unless you ask me.
ikh KOM-uh nikht mit, es zy DEN, doo FRAHKST mikh
More formal. 'es sei denn' introduces the exception and is followed by a normal clause.
Es sei denn, du hast Zeit.
Unless you have time.
es zy DEN, doo hahst tsyt
Short exception clause. The verb comes second in the clause after 'es sei denn'.
Du kannst nicht mitkommen, wenn du nicht fertig bist.
You can't come along unless you're ready.
doo kanst nikht MIT-kom-uhn, ven doo nikht FER-tikh bist
Everyday pattern with modal verb können and a wenn-clause.

Make it make sense
Useful pattern
The most common elementary pattern is a main clause with nicht plus a wenn-clause that also contains nicht: 'Ich gehe nicht, wenn du nicht kommst.' The first nicht negates the main action; the second nicht creates the 'unless' meaning. Word order matters: in the wenn-clause, the conjugated verb goes to the end: 'wenn du nicht kommst', not 'wenn du kommst nicht'. A more formal alternative is 'es sei denn': 'Ich gehe nicht, es sei denn, du kommst.' Here 'es sei denn' means 'unless' or 'except if'.
When to use it
Use the wenn ... nicht pattern in everyday conversation, especially when the condition is a real possibility: 'Wir gehen nicht ins Kino, wenn es regnet.' Use 'es sei denn' when you want to add an exception in a slightly more formal or careful way: 'Ich rufe dich nicht an, es sei denn, es ist wichtig.' In both patterns, keep the verb in the correct position. In a wenn-clause, the verb goes last; after 'es sei denn', the following clause has normal word order with the verb second.
Listen to each line, then take one part and reply out loud.
Kommst du mit ins Kino?
Are you coming to the cinema with us?KOMST doo mit ins KEE-nohIch komme nicht mit, wenn du nicht auch kommst.
I won't come along unless you come too.ikh KOM-uh nikht mit, ven doo nikht owkh KOMSTIch komme mit, es sei denn, ich muss länger arbeiten.
I'll come along unless I have to work longer.ikh KOM-uh mit, es zy DEN, ikh moos LENG-er AR-by-tuhnGut. Dann warten wir nicht, wenn du nicht bis sechs Uhr da bist.
Good. Then we won't wait unless you're there by six o'clock.goot. dan VAR-tuhn veer nikht, ven doo nikht bis zeks oor dah bistA little context goes a long way
In everyday German, the wenn ... nicht pattern is more common in speech, while 'es sei denn' sounds a little more formal or deliberate. In Austria and Switzerland, standard German is used in writing, but regional dialects may prefer different everyday wording. For learners, both patterns are widely understood.
One thing to watch for
Putting nicht after the verb in a wenn-clause: 'wenn du kommst nicht'.
Try this instead: In a German wenn-clause, the conjugated verb goes to the end. Say 'wenn du nicht kommst'. The nicht comes before the final verb: 'Ich gehe nicht, wenn du nicht kommst.'
Your turn
Try answering out loud before checking a possible answer.

Ich gehe nicht, wenn du nicht kommst.
This uses the everyday wenn ... nicht pattern. 'Ich gehe nicht, es sei denn, du kommst' is also correct but more formal.
2Translate: 'We won't start unless it stops raining.'
Show a sample answer
Wir fangen nicht an, wenn es nicht aufhört zu regnen.
The separable verb anfangen splits: 'Wir fangen nicht an'. The wenn-clause ends with 'aufhört zu regnen'.
3Translate: 'I'll come unless I have to work.'
Show a sample answer
Ich komme, es sei denn, ich muss arbeiten.
'es sei denn' introduces the exception. The following clause has normal word order: 'ich muss arbeiten'.
To say 'unless' in German, use a wenn-clause with nicht for everyday speech, or 'es sei denn' for a more formal exception. Keep the verb at the end of the wenn-clause.
