Spillekortet er rødt.

Because spillekortet is definite: it means the playing card.

In Danish, the definite article is usually added to the end of the noun as a suffix:

• et spillekort = a playing card
• spillekortet = the playing card

So English uses a separate word (the), but Danish often attaches that meaning directly to the noun.

The ending -et is the definite article for many neuter nouns in Danish.

Here the base noun is:

• et spillekort = a playing card

Since spillekort is a neuter noun (it takes et in the indefinite form), its definite singular form is:

• spillekortet = the playing card

A very common pattern is:

• et hus → huset
• et kort → kortet
• et spillekort → spillekortet

Yes. Danish very often combines nouns into one word.

Here:

• spille = related to playing / game
• kort = card

Together, spillekort means playing card.

This is extremely common in Danish. Where English may use two words, Danish often prefers one compound word.

Because the adjective must agree with the noun, and spillekort is neuter.

The basic form of the adjective is:

• rød = red

But with a singular neuter noun, the adjective usually takes -t:

• et kort er rødt
• spillekortet er rødt

Compare:

• en bil er rød = the/a car is red
• et kort er rødt = the/a card is red

So rødt is used because the thing being described is a neuter singular noun.

Yes. In this sentence, the adjective is used predicatively—that means it comes after er and describes the subject.

With predicative adjectives in Danish, the important agreement here is mainly gender and number, not whether the noun is definite or indefinite.

So you get:

• et kort er rødt
• kortet er rødt

Both use rødt because the subject is still singular neuter.

Compare with plural:

• kortene er røde = the cards are red

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

So:

• English: the playing card
• Danish: spillekortet

This is one of the biggest differences from English. Danish does have cases where a separate definite word appears, especially with adjectives before nouns, but in a simple sentence like this, the noun just takes the definite ending.

The word order is very straightforward:

• Spillekortet = subject
• er = verb
• rødt = subject complement / adjective

So the structure is basically:

• Subject + verb + adjective

This is similar to English:

• The playing card is red.

Er is the present tense of at være, which means to be.

So:

• jeg er = I am
• du er = you are
• det er = it is

In this sentence, er links the subject (spillekortet) with its description (rødt). It works just like is in English.

You would say:

• Et spillekort er rødt.

The difference is:

• Et spillekort = a playing card
• Spillekortet = the playing card

The adjective stays rødt in both sentences because spillekort is still a singular neuter noun.

A rough guide is that rød sounds something like ruhth / rœð and rødt adds a final t, though the exact Danish pronunciation is difficult for English speakers.

A few things to notice:

• ø is not like ordinary English o
• the d in rød is usually a soft Danish d, not a strong English d
• in rødt, the final t is pronounced

The safest approach is to listen carefully to native audio and imitate it, because Danish pronunciation is often less phonetic than spelling suggests.

Yes. Because spillekortet is definite, it usually refers to a specific playing card that is already known from the context.

For example:

• a card you are holding
• a card just mentioned
• the card everyone is looking at

So the sentence sounds like The playing card is red, not just a general statement about playing cards in general.
