Het kinderdagverblijf biedt kinderopvang aan.

Because kinderdagverblijf is a het-word.

A useful rule for compounds in Dutch is this:

• the last part of the compound usually determines the gender and article

Here, the last part is verblijf, and verblijf is a het-word. So:

• het verblijf
• het kinderdagverblijf

So the sentence begins with Het kinderdagverblijf ...

It is a compound noun:

• kinder = children / child-
• dag = day
• verblijf = stay, residence, place of staying

Together, kinderdagverblijf means a daycare center or day nursery: a place where children stay during the day.

Dutch often builds long nouns by combining smaller words, so this kind of word is very common.

In Dutch compounds, you often do not use the full plural form you might expect.

So although kinderen means children, the compound form is often kinder-:

• kinderboek = children’s book
• kinderfiets = children’s bicycle
• kinderopvang = childcare
• kinderdagverblijf = daycare center

So kinder- here is just the normal combining form in compounds. You do not need to think of it as the regular standalone plural.

Biedt is the present tense, third-person singular form of bieden, meaning to offer.

The basic verb forms are:

• ik bied = I offer
• jij biedt = you offer
• hij/zij/het biedt = he/she/it offers

Since het kinderdagverblijf is singular, Dutch uses:

• biedt

So:

• Het kinderdagverblijf biedt ... aan.
• The daycare center offers ...

Because the full verb is aanbieden, which is a separable verb.

In a normal main clause, separable verbs split:

• aanbieden → biedt ... aan

So:

• Het kinderdagverblijf biedt kinderopvang aan.

This is one of the most common things English speakers need to get used to in Dutch.

A few examples of the same pattern:

• Ik bel je op. = I call you up.
• Zij nodigt ons uit. = She invites us.
• Het bedrijf biedt cursussen aan. = The company offers courses.

But when the verb is not split, it stays together, for example in an infinitive or often at the end of a subordinate clause:

• Het kinderdagverblijf wil kinderopvang aanbieden.
• ... omdat het kinderdagverblijf kinderopvang aanbiedt.

No, not in a normal main clause.

In a Dutch main clause, the finite verb usually comes in second position. With a separable verb, the main verb part goes in position two, and the prefix goes to the end.

So the correct main-clause order is:

• Het kinderdagverblijf biedt kinderopvang aan.

Not:

• Het kinderdagverblijf aanbiedt kinderopvang.

However, aanbiedt is correct when the verb is not split, for example in a subordinate clause:

• Ik weet dat het kinderdagverblijf kinderopvang aanbiedt.

Because kinderopvang is being used in a general, uncountable sense here, like childcare in English.

Compare:

• Het kinderdagverblijf biedt kinderopvang aan. = The daycare center offers childcare.

You are talking about the service in general, not one specific item.

If you were referring to specific childcare in a particular context, an article might appear, but in this sentence the zero article is the natural choice.

This is a very useful distinction:

• kinderdagverblijf = the place/institution
• kinderopvang = the service of childcare

So in the sentence:

• Het kinderdagverblijf = the daycare center
• biedt kinderopvang aan = offers childcare

A rough English parallel would be:

• The daycare center offers childcare.

You would not normally swap those two words, because they do different jobs in the sentence.

This is standard Dutch main-clause word order:

• subject: Het kinderdagverblijf
• finite verb: biedt
• object: kinderopvang
• separable prefix: aan

So the pattern is:

• Subject + finite verb + object + separable prefix

This is very normal Dutch syntax. English speakers often expect the full verb to stay together, but Dutch often splits it.

It is a long word, but it becomes easier if you break it into parts:

• kinder
• dag
• verblijf

A rough English-style guide is:

• KIN-der-dakh-ver-blaif

A few pronunciation notes:

• g in dag is the Dutch guttural g/ch sound, not an English g as in go
• ij in verblijf sounds roughly like eye
• stress is mainly near the beginning: KIN-der-dag-ver-blijf

Even if your pronunciation is not perfect, Dutch speakers will usually understand you if you say the parts clearly.

Yes, very common.

The combination:

• kinderopvang aanbieden

is a standard way to say:

• to offer childcare

Dutch often uses aanbieden with services, products, or opportunities:

• De school biedt extra lessen aan. = The school offers extra lessons.
• Het hotel biedt ontbijt aan. = The hotel offers breakfast.
• De organisatie biedt hulp aan. = The organization offers help.

So this sentence sounds natural and idiomatic.

If the subject becomes plural, the verb changes too.

Singular:

• Het kinderdagverblijf biedt kinderopvang aan.

Plural:

• De kinderdagverblijven bieden kinderopvang aan.

Notice the changes:

• het kinderdagverblijf → de kinderdagverblijven
• biedt → bieden

So Dutch marks plural both in the noun and in the verb form.
