Dutch Negation: When to Use Niet or Geen

In Dutch, we usually negate with two words: "niet" and "geen." You can think of this as choosing between "not" and "no / not any."

Core idea: use geen when you negate a noun and mean "no / not any." It is also the negative partner of een, and it still works with plurals and uncountable nouns.

Use niet for most other cases: adjectives, verbs, prepositions, pronouns, names, and specific things. So first look at the part you are negating, then choose the word:

A pronoun (mijn, deze, iedereen…)	Dat is niet jouw boek Dat is niet jouw boek. - That is not your book.
Something unique (names, etc.)	Waarom is Pieter niet op kantoor? Waarom is Pieter niet op kantoor? - Why is Pieter not at the office?

How to Actually Choose niet or geen

English handles every negative with a single word: "not." Dutch splits that job in two. When the thing you are negating is a noun that could take "een" or no article at all, Dutch does not say "not a" — it deletes "een" completely and drops in "geen" instead. For everything else — verbs, adjectives, prepositions, names, and nouns that already carry "de" or "het" — Dutch reaches for "niet."

So don't translate word by word. Run the quick test from the tip box above: look at the part you are negating and ask whether a bare noun (no de/het/mijn/deze) sits right there. If yes, geen takes the place of "een" — the two never stand side by side. If no, niet goes in, usually right after the verb or at the very end of the sentence.

Mistakes English Speakers Make

English negates by adding "not" in front of the verb or noun and leaving everything else alone, so learners often keep "een" out of habit or put "niet" first the way "not" comes first in English. Check yourself against these four slips.
