Position of negation (niet)

In Dutch, we negate sentences using niet (not). While it always comes after the main conjugated verb, its exact placement depends on the other words in the sentence.

After Definite Objects

A definite object refers to a specific thing, like a pronoun (het, jou) or a noun with a definite article (de / het) or demonstrative (dit / dat).

niet must come after a definite object. Because of this, it often lands at the very end of a simple sentence.

I do not know it.
Ik weet het niet.
I do not understand you.
Ik begrijp jou niet.
We do not know the truth.
We weten de waarheid niet.

Using "Helemaal niet"

To say "not at all", use helemaal niet. It acts as a single unit and follows the exact same placement rules.

completely
helemaal
I do not understand you at all.
Ik begrijp jou helemaal niet.
We do not accept the result at all.
We accepteren het resultaat helemaal niet.

After Time Phrases

niet is also placed after any time expressions (like vandaag or morgen).

She is not changing the decision tomorrow.
Ze verandert de beslissing morgen niet.
We do not understand you today.
We verstaan u vandaag niet.

Before Final Verbs

When a sentence has a second verb at the end of the clause (like an infinitive), niet still goes after definite objects and time phrases, but immediately before that final verb.

I do not want to read the contract today.
Ik wil het contract vandaag niet lezen.
