Het verhuisbedrijf gaf het adres door.

They do two different jobs:

• The first Het in Het verhuisbedrijf is the article the.
• The second het in het adres is also the article the.

So the structure is simply:

• Het verhuisbedrijf = the moving company
• het adres = the address

Both verhuisbedrijf and adres are het-words in Dutch, so they take het, not de.

Verhuisbedrijf is a compound noun:

• verhuizen = to move house / relocate
• bedrijf = company / business

So verhuisbedrijf literally means something like moving company or removal company.

Dutch forms compound nouns very often, much more freely than English.

Because the verb here is the separable verb doorgeven.

• Full infinitive: doorgeven
• In a main clause, Dutch often splits separable verbs:
  • the main verb part is conjugated
  • the prefix goes to the end

So:

• doorgeven → gaf ... door

That is why you get:

• Het verhuisbedrijf gaf het adres door.

This is one of the most important Dutch word-order patterns to learn.

Here doorgeven means something like:

• to pass on
• to forward
• to relay

So the sentence means that the moving company passed on / forwarded the address.

The exact English translation depends on context, but the Dutch verb suggests that the address was communicated onward to someone else.

Because gaf is the simple past form of geven.

Here are the relevant forms:

• geven = to give
• geeft = gives
• gaf = gave
• gegeven = given

Since the sentence talks about a completed action in the past, Dutch uses gaf.

With the separable prefix added back, the full past idea is:

• doorgeven → gaf ... door = passed on

It is based on geven, which is irregular.

That is why the past tense is:

• geven → gaf
• not something regular like geefde

With the separable prefix:

• ik geef door = I pass on
• ik gaf door = I passed on
• ik heb doorgegeven = I have passed on

So you need to learn it as an irregular separable verb.

The sentence follows the standard Dutch main-clause pattern:

Subject + finite verb + object + separable prefix

So:

• Het verhuisbedrijf = subject
• gaf = finite verb
• het adres = direct object
• door = separable prefix

Pattern:

• Het verhuisbedrijf | gaf | het adres | door.

This is very typical Dutch main-clause word order.

Yes. A very natural alternative is:

• Het verhuisbedrijf heeft het adres doorgegeven.

That is the present perfect.

So you have two common past ways to say it:

• Het verhuisbedrijf gaf het adres door. = simple past
• Het verhuisbedrijf heeft het adres doorgegeven. = present perfect

In everyday spoken Dutch, the perfect tense is often very common, especially in conversation.

Dutch does not have to mention the receiver if it is already clear from context or not important.

So this sentence only tells you that the moving company passed the address on. It does not specify the recipient.

If you wanted to include that, you could say for example:

• Het verhuisbedrijf gaf het adres door aan de klant.
• Het verhuisbedrijf gaf de klant het adres door.

Both mean that the moving company passed the address on to the customer, though the wording is slightly different.

Because adres is a neuter noun in Dutch, and neuter singular nouns take het.

So:

• het adres
• not de adres

This is something you mostly have to learn noun by noun. Unfortunately, Dutch gender is not always predictable.

No. It is split mainly in main clauses with a finite verb.

In other structures, it often comes back together.

Compare:

• Het verhuisbedrijf gaf het adres door.
  main clause → split

• ... omdat het verhuisbedrijf het adres doorgaf.
  subordinate clause → together

• Het verhuisbedrijf heeft het adres doorgegeven.
  perfect tense with past participle → together

So learners should think of the dictionary form as doorgeven, even when they often see it split.

The main stress is usually on huís:

• ver-HUIS-be-drijf

A rough English-style guide would be:

• ver-HOUSE-buh-drayf

A few pronunciation notes:

• ui is a Dutch diphthong that does not exist exactly in English
• ij in bedrijf sounds somewhat like the vowel in eye, though not exactly
• gaf has a broad a, somewhat like ah in many accents

If pronunciation matters, compounds like this are often easier once you can hear them spoken.

Yes. Doorgeven has several related meanings depending on context, such as:

• to pass on information
• to forward
• to hand something along
• to report
• sometimes even to continue passing something physically

In this sentence, with het adres, the most likely meaning is to pass on / forward the address rather than physically hand over a written card, though context decides the exact nuance.
