Questions & Answers about De houder registreert het chipnummer.

Why does the sentence use de in de houder but het in het chipnummer?

Dutch nouns have grammatical gender, and singular definite articles depend on that:

• de is used with common-gender nouns
• het is used with neuter nouns

So:

• houder is a de-word → de houder
• chipnummer is a het-word → het chipnummer

This is something you usually have to learn with each noun. In the plural, both would take de:

• de houders
• de chipnummers

What exactly does houder mean here?

Houder literally means holder, but in real usage it often means the person who officially possesses, keeps, or is responsible for something.

Depending on context, it can mean something like:

• holder
• owner
• keeper
• registered keeper

In a sentence about a chip number, it likely refers to the person responsible for the animal or object with that chip.
