Kunden gemmer garantibeviset med henblik på at reklamere.

Because kunden is the definite singular form of kunde (customer).

In Danish, nouns usually do not take a separate word for the in the singular. Instead, the definite article is attached to the end of the noun:

• en kunde = a customer
• kunden = the customer

So kunden means the customer.

For the same basic reason: it is the definite singular form, but this noun is neuter.

• et garantibevis = a warranty certificate / warranty document
• garantibeviset = the warranty certificate

The ending -et shows both:

1. that the noun is neuter (like nouns that take et), and
2. that it is definite.

Because Danish usually expresses definiteness by adding an ending to the noun instead of using a separate article.

Compare:

• en kunde = a customer

• kunden = the customer

• et garantibevis = a warranty certificate
• garantibeviset = the warranty certificate

So English uses a separate word (the), but Danish often uses a suffix.

Yes. Danish very often combines nouns into one compound word.

Here:

• garanti = guarantee / warranty
• bevis = proof / certificate / document

Together:

• garantibevis = warranty certificate / proof of warranty

This is very normal in Danish. English sometimes writes similar ideas as two words, but Danish often prefers one compound noun.

Gemmer is the present tense of gemme.

• at gemme = to keep / to save / to store
• gemmer = keeps / saves / stores

So Kunden gemmer garantibeviset means something like The customer keeps the warranty certificate.

Depending on context, gemme can mean:

• keep
• save
• put away
• store

Because med henblik på at is a fixed expression meaning with a view to, for the purpose of, or more naturally in order to.

So the pattern is:

• med henblik på at + infinitive

Here:

• med henblik på at reklamere

This means with the intention of complaining / making a claim.

Even though på is a preposition, this whole expression works as a set phrase, and it is normal for it to be followed by at + infinitive.

It is a formal expression meaning something like:

• with a view to
• for the purpose of
• with the intention of
• in order to

So the whole sentence has a slightly formal tone.

A more everyday way to express a similar idea might be:

• Kunden gemmer garantibeviset for at reklamere.

That is simpler and more conversational.

Yes, this is an important false friend.

In Danish, reklamere can mean different things depending on context:

• reklamere for noget = advertise / promote something
• reklamere in a consumer context = complain about a product, especially make a claim because something is faulty

In this sentence, because of garantibeviset (the warranty certificate), reklamere clearly means something like:

• make a complaint
• make a claim
• claim under the warranty

So it does not mean advertise here.

Because in Danish, reklamere can be used without directly naming the thing complained about when the context is clear.

Here, the context already suggests that the customer may need the warranty certificate in case there is a problem with a product. So at reklamere can stand by itself.

If needed, Danish could be more specific, for example:

• reklamere over varen = complain about the item
• reklamere over fejlen = complain about the defect

But leaving it without an object is natural here.

Yes. It follows the standard Danish main-clause pattern:

• Kunden = subject
• gemmer = finite verb
• garantibeviset = object
• med henblik på at reklamere = purpose phrase

So it is a normal subject–verb–object structure, followed by an adverbial phrase of purpose.

Yes. Danish can move that purpose phrase to the front for emphasis:

• Med henblik på at reklamere gemmer kunden garantibeviset.

That is grammatical, but it sounds more formal and marked. The original version is the more neutral word order.

Also notice that when something other than the subject comes first in a Danish main clause, the verb still stays in second position:

• Med henblik på at reklamere
  • gemmer
    • kunden
      • garantibeviset

It can often do either, depending on context.

In isolation, kunden most literally means the customer, so it can refer to:

1. a specific customer already known from the context, or
2. a generic customer in instructions, policies, or explanatory writing

In practical or formal language, Danish often uses the singular definite form this way, where English might also say something general like the customer.

Yes, somewhat. The main reason is the phrase med henblik på, which is more formal or administrative in tone.

The sentence sounds like something from:

• store policy text
• warranty information
• legal or customer-service writing

A more everyday version would be:

• Kunden gemmer garantibeviset for at kunne reklamere.
• Kunden gemmer garantibeviset, hvis der skal reklameres senere.

So the original sentence is correct, but it has a slightly formal written style.
