De betaler for tjenesten.

Because it is the first word in the sentence.

If the meaning is they, Danish normally writes it as de in the middle of a sentence, for example:

• Jeg ved, at de betaler for tjenesten. = I know that they are paying for the service.

A capital De can also be a polite/formal you in some writing, but in a sentence-initial position you cannot tell that from the capital letter alone. You need context.

In most learning contexts, De here means they.

So the structure is:

• De = they
• betaler = pay / are paying
• for tjenesten = for the service

As noted, De could also be formal you in some contexts, but that usage is less common in modern everyday Danish.

Betaler is the present tense form of at betale = to pay.

Danish verbs are much simpler than English verbs in one important way: the verb usually does not change depending on the subject.

So you get:

• jeg betaler = I pay
• du betaler = you pay
• han betaler = he pays
• de betaler = they pay

Notice that Danish does not add different endings like English pay / pays.

It can mean either, depending on context.

Danish present tense often covers both:

• they pay
• they are paying

So De betaler for tjenesten could mean either:

• They pay for the service
• They are paying for the service

Context tells you which is more natural.

Because Danish often uses betale for when talking about paying for something you receive.

• betale for noget = pay for something

So:

• De betaler for tjenesten = They pay for the service

However, Danish can also use betale directly with some objects, especially bills, amounts, or prices:

• De betaler regningen. = They pay the bill.
• Jeg betalte 200 kroner. = I paid 200 kroner.

So both patterns exist, but betale for tjenesten is completely normal.

Tjenesten is the definite singular form of tjeneste.

• en tjeneste = a service
• tjenesten = the service

Danish usually puts the definite article at the end of the noun instead of using a separate word like English the.

So the ending -en here means the.

Because that is how Danish usually forms the definite noun.

Compare:

• en tjeneste = a service
• tjenesten = the service

This is very common in Danish:

• en bil → bilen = the car
• et hus → huset = the house

So instead of putting a separate word before the noun, Danish often adds the definite ending directly to the noun.

The basic order here is:

subject + verb + prepositional phrase

So:

• De = subject
• betaler = finite verb
• for tjenesten = prepositional phrase

This gives:

• De betaler for tjenesten.

This is a normal main-clause pattern in Danish.

In a normal main clause, yes, Danish follows the V2 rule, meaning the finite verb usually comes in the second position.

In this sentence:

• De is in first position
• betaler is in second position

If you move something else to the front, the verb still stays second:

• I dag betaler de for tjenesten. = Today they are paying for the service.

Notice that when I dag moves to the front, betaler still stays second, and de moves after the verb.

A rough learner-friendly pronunciation is:

• betaler ≈ beh-TAH-luh

A few notes:

• The stress is usually on -ta-
• The final -er in Danish is often reduced and not pronounced like clear English er
• Danish pronunciation is often softer and more reduced than the spelling suggests

If you want a rough full sentence pronunciation:

• De betaler for tjenesten ≈ dee beh-TAH-luh for tyeh-neh-sten

That is only approximate, but it helps as a first step.

A rough approximation is:

• tjenesten ≈ TYEH-neh-sten

But be careful: Danish tj does not sound exactly like English ty. It is a softer sound that many learners need time to get used to.

Also:

• the first syllable is stressed
• the vowels are more reduced than an English speaker may expect

It is best to hear native audio if possible, because Danish pronunciation is often less phonetic than the spelling suggests.

Yes.

Tjeneste can mean service, but depending on context it can also refer to:

• a service provided by a company or institution
• a duty or period of service
• a favor, in some contexts

For example:

• en streamingtjeneste = a streaming service
• militærtjeneste = military service
• Kan du gøre mig en tjeneste? = Can you do me a favor?

So the exact meaning depends on context.

Yes, it is a natural sentence.

It sounds like a neutral, standard way to say that someone is paying for a service. In real life, people might also say more specific things depending on context, such as:

• De betaler for abonnementet. = They pay for the subscription.
• De har betalt for tjenesten. = They have paid for the service.
• De skal betale for tjenesten. = They have to pay for the service.

But De betaler for tjenesten is perfectly normal Danish.

You would use betalte, the past tense of betale:

• De betalte for tjenesten. = They paid for the service.

A few useful related forms are:

• at betale = to pay
• betaler = pay / are paying
• betalte = paid
• har betalt = have paid

So if you want the present perfect:

• De har betalt for tjenesten. = They have paid for the service.
