This is a hands-on page. You already know the core rule that Dutch has two negators — geen and niet — and which one to pick. Here we drill the actual act of turning a positive sentence into a negative one, step by step, until it's automatic. English has only one word for this ("not"), so the very idea of choosing a negator is the new skill. The good news: there is a single test, and once you run it a few dozen times it becomes a reflex.
The one test, then build
Before you negate anything, ask yourself one question:
Am I negating an indefinite noun — a noun you could put een in front of, or a bare plural, or a bare mass noun?
- Yes → use geen, and put it where een would go.
- No → use niet, placed late in the clause.
That's the entire decision. Everything below is just practice running it.
Building with geen: swap it in for the article
When the thing you're negating is an indefinite noun, geen replaces the article — it stands exactly where een stood, or where the "nothing" stood in front of a bare plural or mass noun. You don't add a separate "not"; geen bundles "not" and "a/any" into one word.
Ik heb een auto → Ik heb geen auto.
Ik heb een auto. → Ik heb geen auto.
I have a car. → I don't have a car. ('geen' takes the place of 'een')
Ik drink koffie. → Ik drink geen koffie.
I drink coffee. → I don't drink coffee. (bare mass noun → geen)
We hebben tijd. → We hebben geen tijd.
We have time. → We don't have time. (bare mass noun → geen)
Er liggen appels op tafel. → Er liggen geen appels op tafel.
There are apples on the table. → There are no apples on the table. (bare plural → geen)
Notice geen sits right before the noun (and before any adjective on it): geen grote auto (no big car), geen lekkere koffie (no nice coffee).
Ik heb geen kleine kinderen meer.
I don't have small children anymore. ('geen' before the adjective + noun)
Building with niet: place it late
If the thing you're negating is not an indefinite noun — a whole action, an adjective, an adverb, a definite noun, a name — you use niet, and the safe default position is late in the clause, usually at or near the end. For a plain "I don't do X" sentence, niet simply goes to the end.
Ik werk → Ik werk niet.
Ik werk. → Ik werk niet.
I work. → I don't work. ('niet' goes to the end)
Hij komt vanavond. → Hij komt vanavond niet.
He's coming tonight. → He's not coming tonight. ('niet' after the time word, at the end)
Ik ken hem. → Ik ken hem niet.
I know him. → I don't know him. ('niet' after the object pronoun, at the end)
When niet targets one specific element rather than the whole action, it goes right in front of that element — before the adjective, the adverb, or the prepositional phrase it negates.
Het is groot. → Het is niet groot.
It's big. → It's not big. ('niet' directly before the adjective)
We gaan naar de bioscoop. → We gaan niet naar de bioscoop.
We're going to the cinema. → We're not going to the cinema. ('niet' before the prepositional phrase)
Hij rijdt snel. → Hij rijdt niet snel.
He drives fast. → He doesn't drive fast. ('niet' before the adverb)
The crucial case: definite nouns take niet, not geen
This is where English speakers slip, so drill it on purpose. A noun is definite when it carries de, het, deze, die, dit, dat, mijn, jouw... or is a proper name. Definite nouns are not indefinite, so they are negated with niet, never geen. Compare the same noun two ways:
| Indefinite → geen | Definite → niet |
|---|---|
| Ik heb geen auto. (I don't have a car.) | Ik wil de auto niet. (I don't want the car.) |
| Ze drinkt geen koffie. (She doesn't drink coffee.) | Ze wil deze koffie niet. (She doesn't want this coffee.) |
Ik ken die man niet.
I don't know that man. ('die man' is definite → niet)
Ik vind mijn sleutels niet.
I can't find my keys. ('mijn sleutels' is definite → niet)
Common Mistakes
❌ Ik heb niet een auto.
Incorrect — to negate an indefinite noun, use 'geen', which already replaces 'een'. 'niet een' is not how Dutch does it.
✅ Ik heb geen auto.
I don't have a car.
❌ Ik heb niet tijd.
Incorrect — 'tijd' is a bare mass noun, so it's negated with 'geen', not 'niet'.
✅ Ik heb geen tijd.
I don't have time.
❌ Ik ken geen die man.
Incorrect — 'die man' is a definite noun, so it takes 'niet', not 'geen'.
✅ Ik ken die man niet.
I don't know that man.
❌ Het is geen groot.
Incorrect — 'groot' is an adjective, not an indefinite noun; negate it with 'niet'.
✅ Het is niet groot.
It's not big.
❌ Ik niet werk vandaag.
Incorrect — 'niet' doesn't go before the verb like English 'don't'; it goes late, at the end: 'Ik werk vandaag niet'.
✅ Ik werk vandaag niet.
I'm not working today.
Key Takeaways
- Run one test: negating an indefinite noun (een / bare plural / bare mass) → geen; everything else → niet.
- geen replaces the article and sits right before the noun — never niet een, never geen de.
- niet goes late (end of the clause) for whole-action negation, and right before the adjective, adverb or phrase it targets.
- Definite nouns (de/het/deze/die/mijn/names) are negated with niet, not geen.
- Don't put niet before the verb the way English puts "don't" — Dutch keeps it near the end.
