Kortmisbruget er et problem.

It is a compound noun:

• kort = card
• misbrug = misuse / abuse
• kortmisbrug = card misuse
• kortmisbruget = the card misuse / the misuse of cards

Danish forms compounds very freely, much like German. In compounds, English often uses separate words, but Danish often joins them into one word.

The ending -et is the definite article attached to the noun, meaning the.

So:

• et misbrug = a misuse / an abuse
• misbruget = the misuse / the abuse
• kortmisbrug = card misuse
• kortmisbruget = the card misuse

Unlike English, Danish usually puts the at the end of the noun instead of before it.

Because problem is a neuter noun in Danish.

Danish nouns have two genders:

• en-words (common gender)
• et-words (neuter)

So you say:

• et problem = a problem
• problemet = the problem

You just have to learn the gender with each noun.

In Danish compounds, the last part usually decides the gender.

Here, the last part is misbrug:

• et misbrug
• therefore et kortmisbrug
• and in the definite form: kortmisbruget

This is a very useful rule for Danish compound nouns.

Because Danish normally uses the suffixed definite article instead.

So English says:

• the problem
• the card misuse

But Danish says:

• problemet
• kortmisbruget

A separate definite word such as det is usually used only in special cases, for example with adjectives:

• problemet = the problem
• det store problem = the big problem

Because Danish main clauses normally follow V2 word order, which means the finite verb comes in the second position.

Here:

1. Kortmisbruget
2. er
3. et problem

So the normal order is:

• Kortmisbruget er et problem.

This is similar to ordinary English word order in simple statements.

Er is the present tense of at være = to be.

So:

• jeg er = I am
• du er = you are
• det er = it is
• kortmisbruget er et problem = the card misuse is a problem

In a compound like kortmisbrug, the first part often appears in a basic form and does not clearly mark singular or plural the way English might.

So kortmisbrug can be understood as misuse of cards or card misuse, depending on context.

This is normal in Danish compounds. The first element often works more like a category label than a separately counted noun.

Yes. That is also natural Danish.

Compare:

• Kortmisbrug er et problem = Card misuse is a problem
• Misbrug af kort er et problem = Misuse of cards is a problem
• Kortmisbruget er et problem = The card misuse is a problem

The version with -et sounds more definite and specific, while the others can sound more general.

Because the sentence means that the card misuse belongs to the category a problem.

This is the same idea as in English:

• The card misuse is a problem
• not usually The card misuse is the problem unless you mean it is the specific problem being discussed

So in Danish:

• Kortmisbruget er et problem = category/classification
• Kortmisbruget er problemet = it is the problem

That second version is much stronger and more specific.

A rough guide is:

• kort ≈ kort
• misbrug ≈ MIS-broo
• kortmisbruget ≈ KORT-mis-broo-eth

A few notes:

• g at the end of misbrug is often weak or softened in normal speech
• the final -et is usually pronounced very lightly
• Danish pronunciation is often less phonetic than spelling suggests

If you are learning to say it naturally, it helps to hear native audio, because the written form does not show all the sound reductions clearly.

Yes. Danish very often creates new nouns by combining existing ones into one word.

Examples of the same pattern:

• kreditkort = credit card
• kortbetaling = card payment
• identitetstyveri = identity theft

So kortmisbrug is completely normal Danish word-building.

Often, yes, depending on context. Kort in modern Danish frequently means a payment card, bank card, or credit card when used in this kind of context.

So kortmisbrug can refer to:

• unauthorized use of a card
• card fraud
• misuse of payment cards

The exact English translation depends on the situation.
