Kunden betaler klagegebyret før svarfristen.

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

• kunde = customer

• kunden = the customer

• gebyr = fee

• gebyret = the fee

• svarfrist = response deadline
• svarfristen = the response deadline

Very roughly:

• -en is a common singular definite ending
• -et is a neuter singular definite ending

So these endings are not extra case endings; they are the Danish way of saying the.

For simple nouns, Danish normally uses a suffixed definite article, not a separate word.

So English:

• the customer
• the complaint fee
• the response deadline

becomes Danish:

• kunden
• klagegebyret
• svarfristen

A separate definite word such as den or det is usually used when there is an adjective:

• kunden = the customer
• den nye kunde = the new customer

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

• at betale = to pay
• betaler = pays / is paying

In a sentence like this, the present tense often describes a rule, procedure, or general fact, not necessarily something happening right this second. So it can feel like English pays, must pay, or is to pay, depending on context.

Because Danish verbs do not change according to person the way English verbs sometimes do.

In English:

• I pay
• you pay
• he/she pays

In Danish, the present tense stays the same:

• jeg betaler
• du betaler
• kunden betaler
• de betaler

So betaler works for all persons in the present tense.

It is a compound noun:

• klage = complaint
• gebyr = fee
• klagegebyr = complaint fee
• klagegebyret = the complaint fee

Danish makes compounds very freely, and they are normally written as one word. The last part is the main noun, so klagegebyr is literally a kind of gebyr.

Because Danish usually writes compound nouns as a single word.

• svar = answer / response
• frist = deadline / time limit
• svarfrist = response deadline
• svarfristen = the response deadline

This is very common in Danish. English often writes similar things as two words, but Danish prefers one word.

It is a prepositional time phrase.

• før = before
• svarfristen = the response deadline

So før svarfristen means before the response deadline.

Here før is followed by a noun phrase, not a full clause. Compare:

• før svarfristen = before the deadline
• før kunden svarer = before the customer replies

This is the normal neutral order for a Danish main clause:

subject + finite verb + object + time expression

So:

• Kunden = subject
• betaler = finite verb
• klagegebyret = object
• før svarfristen = time phrase

Danish main clauses follow the verb-second principle, often called V2. That means the finite verb normally comes in the second position.

If you move the time phrase to the front, the verb still stays second:

• Før svarfristen betaler kunden klagegebyret.

That inversion is very typical in Danish.

No. The -en ending here marks definiteness, not subjecthood.

Kunden means the customer, whether it is subject or object. Danish does not show subject/object by changing the noun ending the way some languages do. You understand the role mainly from word order.

For example:

• Kunden betaler gebyret. = The customer pays the fee.
• Vi kontakter kunden. = We contact the customer.

In both cases, kunden still means the customer.

Sometimes yes, depending on style and nuance, but før is a very natural choice here.

• før = before
• inden can also mean before / by, often with a sense of before a limit is reached

In many real-life contexts, both may be understandable, but før svarfristen is straightforward and idiomatic for before the response deadline.

A learner-friendly way to think of it is:

• før = simple before
• inden = often before/by the time

No. In Danish, common nouns are not capitalized.

So:

• kunden
• klagegebyret
• svarfristen

are lowercase unless they begin the sentence. Kunden is capitalized here only because it is the first word.

This is different from German, where all nouns are capitalized.

It means the deadline or time limit for giving an answer or response.

So svarfristen is not the answer itself. It is the deadline for replying.

That is why før svarfristen means before the deadline for responding.
