eSIM-kortet er digitalt.

-et is the definite article attached to the noun. It means the.

So:

• et eSIM-kort = an eSIM card
• eSIM-kortet = the eSIM card

In Danish, the definite article usually goes at the end of the noun, not before it as in English.

Because Danish normally adds the as an ending on the noun instead of using a separate word.

Compare:

• English: the card
• Danish: kortet

This is very common in Danish:

• bogen = the book
• huset = the house
• kortet = the card

Danish likes to form compound nouns as one written word.

Here, eSIM-kort is a compound meaning eSIM card, and then the definite ending is added:

• eSIM
  • kort = eSIM-kort
• eSIM-kort
  • -et = eSIM-kortet

This is very normal in Danish. English often writes similar things as two words, but Danish often combines them.

Kort is a neuter noun in Danish, so its basic form is:

• et kort = a card

That matters because:

1. the definite ending is -et
2. the adjective later becomes digitalt with -t

So the neuter gender of kort affects both the noun form and the adjective form.

Because digital is describing a singular neuter noun: et kort.

In Danish, adjectives often change form depending on the noun. For a singular neuter noun, many adjectives add -t:

• et digitalt kort = a digital card

The same thing happens when the adjective comes after er:

• Kortet er digitalt = The card is digital

Compare:

• en digital telefon
• et digitalt kort

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

So:

• jeg er = I am
• du er = you are
• det er = it is
• kortet er digitalt = the card is digital

Unlike English, Danish does not change the present tense form here between am / is / are. It stays er.

In this sentence, the word order is straightforward and very similar to English:

• eSIM-kortet = subject
• er = verb
• digitalt = complement

So it follows:

subject + verb + adjective

That said, Danish is a V2 language, which means the verb usually stays in second position in main clauses. But in this simple sentence, it looks just like English.

Yes, but the meaning changes slightly.

• Et eSIM-kort er digitalt = An eSIM card is digital / A(ny) eSIM card is digital
• eSIM-kortet er digitalt = The eSIM card is digital

So the difference is mainly indefinite versus definite:

• et eSIM-kort = an eSIM card
• eSIM-kortet = the eSIM card

eSIM is a technical term/abbreviation, so it keeps its special capitalization.

In Danish, ordinary nouns are not capitalized just because they are nouns. So:

• eSIM-kortet is correct
• digitalt stays lowercase

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

A simple learner-friendly approximation is:

• eSIM: ee-SIM
• kortet: roughly KOR-det

A few helpful notes:

• the stress is mainly on SIM in eSIM
• kortet may sound softer than the spelling suggests
• the ending -et is usually unstressed

You do not need a perfect pronunciation right away; the important part is recognizing that kortet is the definite form of kort.

Yes.

Before the noun:

• et digitalt eSIM-kort = a digital eSIM card

After the noun with er:

• eSIM-kortet er digitalt = the eSIM card is digital

In both cases, the adjective is digitalt because it refers to a singular neuter noun: et kort.
