Wij noemen de vochtplek en de schimmelvorming.

Yes. Wij means we.

In Dutch, wij is the full form, and we is the unstressed, very common spoken form. In many everyday sentences, Dutch speakers prefer we:

• Wij noemen de vochtplek en de schimmelvorming.
• We noemen de vochtplek en de schimmelvorming.

Both are correct. Wij can sound a bit more emphatic, careful, or formal, depending on context.

Because the subject is wij (we), the verb takes the wij form:

• ik noem
• jij noemt
• hij/zij noemt
• wij noemen
• jullie noemen
• zij noemen

So wij noemen is the correct agreement.

As for word order: Dutch main clauses normally put the conjugated verb in second position. Here the subject comes first, so the verb comes right after it:

• Wij noemen ...

If you start with something else, the verb still stays in second position:

• Vandaag noemen wij de vochtplek en de schimmelvorming.

So noemen wij is possible, but usually only after another element has been placed first, or in a question-like structure.

Noemen can mean several related things in Dutch, including:

• to name
• to call
• to mention

So depending on context, wij noemen ... could mean something like:

• we call ...
• we name ...
• we mention ...

This is a very common Dutch verb, but its exact English translation depends on the situation. That is normal.

A very common pattern is:

• Iets noemen = to mention something
• Iemand/iets X noemen = to call someone/something X

For example:

• Wij noemen het probleem. = We mention the problem.
• Wij noemen hem Jan. = We call him Jan.

Because both vochtplek and schimmelvorming are de-words.

In Dutch, singular nouns usually take either de or het:

• de vochtplek
• de schimmelvorming

When two nouns are linked by en (and), each noun often keeps its own article if both are definite:

• de vochtplek en de schimmelvorming

That is completely normal.

You could compare:

• de muur en de vloer
• de oorzaak en de oplossing

Yes, both are compounds, which is very common in Dutch.

vochtplek

This is made from:

• vocht = moisture, damp
• plek = spot, place, patch

So vochtplek is literally something like moisture spot or damp patch.

schimmelvorming

This is made from:

• schimmel = mold
• vorming = formation, development

So schimmelvorming literally means mold formation or the development of mold.

Dutch often builds longer nouns this way, and English learners should get used to seeing words combined into one.

They are related, but not exactly the same.

• schimmel = mold itself
• schimmelvorming = the formation or development of mold

So schimmelvorming sounds a bit more technical, formal, or descriptive. It focuses on the process or presence developing, not just the substance.

For example:

• Er is schimmel op de muur. = There is mold on the wall.
• Er is schimmelvorming op de muur. = There is mold formation on the wall.

The second version may sound more like a report, inspection, or formal description.

It is grammatical, but whether it sounds natural depends on context.

The sentence can feel a little incomplete on its own, because noemen often needs a reason or a larger setting. For example, in a report or explanation it could work fine:

• In het rapport noemen wij de vochtplek en de schimmelvorming.

Without context, many Dutch speakers might expect something more specific, such as:

• Wij noemen de vochtplek en de schimmelvorming als belangrijkste problemen.
• Wij vermelden de vochtplek en de schimmelvorming in het verslag.

So the sentence is not wrong, but in isolation it may feel a bit formal or unfinished.

Because modern Dutch does not use case endings the way German does in ordinary usage.

In this sentence:

• Wij is the subject
• de vochtplek en de schimmelvorming is the direct object

But the nouns themselves do not change form to show that. Dutch mostly shows grammatical roles through:

• word order
• articles
• pronouns
• context

So unlike in some other languages, you do not need to change vochtplek or schimmelvorming here.

Wij is usually pronounced roughly like English why, though not exactly the same in every accent.

A few useful pronunciation notes:

• wij and ei/ij words often have a sound close to English eye
• g in schimmelvorming is the Dutch guttural g, which may be unfamiliar to English speakers
• compounds are usually spoken as one word, with natural stress on the main parts

A rough learner-friendly approximation might be:

• wij ≈ why
• noemen ≈ NOO-muh-n
• vochtplek ≈ VOCHT-plek
• schimmelvorming ≈ SKHIM-ul-vor-ming

That said, the exact sounds are more Dutch than English spellings can show.

In this sentence, repeating de is the most natural and standard choice:

• de vochtplek en de schimmelvorming

You will sometimes see Dutch omit the second article in certain coordinated phrases, but here that would sound less balanced and less natural, especially because the two nouns are separate, specific things.

So for learners, the safest choice is:

• if both nouns are definite, use the article with both

The difference is mostly about emphasis and style, not grammar.

• we noemen = more common in everyday speech
• wij noemen = a little more formal, careful, or contrastive

For example, wij may be used when you want to stress we rather than someone else:

• Wij noemen de vochtplek en de schimmelvorming, maar zij doen dat niet.

So in normal conversation, we is often the default. In writing or emphasis, wij appears more often.
