English has one word for "not," so an English speaker never expects to pick a negator. Dutch makes you choose between niet and geen on every negated sentence — but the choice comes down to a single yes/no question, and once you've drilled it, it's automatic. This page is the fast decision guide. For the full reasoning and edge cases, see the dedicated Niet vs Geen page; here we just get you choosing correctly in real time.
The one-question flowchart
Ask yourself this about the thing you're negating:
Am I negating an indefinite noun? — a noun with een in front of it, or a bare plural or mass/uncountable noun with no article at all (koffie, tijd, auto's).
- YES → use geen.
- NO (you're negating a verb, an adjective, an adverb, a definite noun, a prepositional phrase, or a name) → use niet.
That single question resolves almost every case. The whole skill is recognising "indefinite noun" fast.
Geen: the indefinite-noun negator
Geen takes the place of een (or of the missing article on a bare plural or mass noun). It sits right where the article would, before the noun and any adjective.
Ik heb een auto. → Ik heb geen auto.
I have a car. → I don't have a car.
Sorry, we hebben geen tijd meer.
Sorry, we've got no time left. (bare mass noun → geen)
Er staan geen stoelen in de kamer.
There are no chairs in the room. (bare plural → geen)
Niet: the everything-else negator
If you're negating anything that isn't a bare indefinite noun, it's niet.
A verb / whole action — niet usually goes to the end:
Ik werk vandaag niet.
I'm not working today.
An adjective — niet right before it:
Deze soep is niet warm genoeg.
This soup isn't warm enough.
A definite noun — anything with de, het, deze, die, mijn, or a name:
Ik ken die man niet.
I don't know that man. (definite 'die man' → niet)
Ik vind Amsterdam niet zo gezellig in de winter.
I don't find Amsterdam all that cosy in winter. (proper name → niet)
Spotting "indefinite" fast
The whole decision hinges on recognising an indefinite noun in a split second. Three quick signals tell you a noun is indefinite — and therefore geen territory:
- It has een in front of it (een fiets, een idee).
- It's a bare plural with no article (fietsen, kinderen, plannen).
- It's a mass/uncountable noun with no article (water, geld, tijd, zin).
If none of those apply — if there's a de, het, deze, die, dit, dat, a possessive like mijn or zijn, or a name — the noun is definite, and you're back to niet. This matters because many everyday phrases are bare mass nouns that English speakers don't feel as nouns to be negated with a special word: honger (hunger), zin (the desire to do something), gelijk (being right). All of them take geen.
Ik heb geen honger, maar wel een beetje dorst.
I'm not hungry, but I am a bit thirsty. (bare mass noun 'honger' → geen)
Nee, daar heb ik echt geen zin in vanavond.
No, I really don't feel like that tonight. (fixed 'zin hebben in' → geen)
Where geen sits in the sentence
Because geen replaces the article, it lands exactly where the article would: directly before the noun, and before any adjective attached to it. You don't push it to the end of the clause the way you often do with niet.
Hij heeft geen goede reden gegeven.
He didn't give a good reason. (geen sits before the adjective + noun)
Er waren geen vrije plekken meer in de trein.
There were no free seats left on the train.
This is a real point of contrast with niet, which often travels to the end of the clause for whole-action negation (Ik werk vandaag niet). Geen never travels — it stays glued to its noun.
Head-to-head: the same noun, both ways
The rule clicks fastest when you negate the same noun two ways. Indefinite gets geen; the moment it goes definite, it flips to niet:
| Indefinite → geen | Definite → niet |
|---|---|
| Ik drink geen koffie. (I don't drink coffee — coffee in general.) | Ik drink deze koffie niet. (I'm not drinking this coffee.) |
| Ik heb geen auto. (I don't have a car.) | Ik neem de auto vandaag niet. (I'm not taking the car today.) |
We hebben geen melk meer, maar de melk die er nog stond, wil ik niet — die is zuur.
We're out of milk, but the milk that was left, I don't want — it's gone off. (geen melk = indefinite; die melk = definite → niet)

Common Mistakes
❌ Ik heb niet een auto.
Incorrect — 'niet een' calques English 'not a'; an indefinite noun takes 'geen', which already absorbs 'een'.
✅ 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'.
✅ Ik heb geen tijd.
I don't have time.
❌ Ik wil geen de soep.
Incorrect — 'geen' can't combine with a definite article; a definite noun takes 'niet'.
✅ Ik wil de soep niet.
I don't want the soup.
❌ Ik ken geen die vrouw.
Incorrect — 'die vrouw' is definite, so it's 'niet', not 'geen'.
✅ Ik ken die vrouw niet.
I don't know that woman.
❌ Deze soep is geen warm.
Incorrect — 'warm' is an adjective, not an indefinite noun, so use 'niet'.
✅ Deze soep is niet warm.
This soup isn't warm.
Key Takeaways
- One question decides it: negating an indefinite noun (een / bare plural / mass) → geen; everything else → niet.
- Geen replaces the article — never niet een, never geen de.
- Definite nouns (de/het/deze/die/mijn/names) always take niet.

- Niet vs Geen: The Core Negation ChoiceA1 — The single test that decides Dutch negation — geen for indefinite nouns, niet for everything else — worked through with clear contrasts and the errors English speakers make.
- Choosing: Die or Dat?B1 — One gender rule covers both uses of die and dat in Dutch — as 'that/those' demonstratives and as relative pronouns: de-words and all plurals take die, singular het-words take dat — with a flowchart, head-to-head contrasts, and the errors English speakers make.
- De vs Het: The Definite ArticleA1 — Dutch has two words for 'the': het for neuter singular nouns only, and de for common-gender singulars and ALL plurals. The choice is fixed per noun and drags the demonstratives (dit/dat vs deze/die) and the adjective ending along with it — including the one place an adjective loses its -e: een mooi huis.
