Questions & Answers about Udløbsdatoen står på kortet.
Because -en marks the definite form of the noun: the expiry date.
- udløbsdato = expiry date / expiration date
- udløbsdatoen = the expiry date
In Danish, the definite article is usually attached to the end of the noun instead of being a separate word like the in English.
Because kort is a neuter noun.
Danish nouns usually belong to one of two genders:
- common gender → often takes -en in the definite singular
- neuter gender → often takes -et in the definite singular
So:
- et kort = a card
- kortet = the card
That is why the sentence says på kortet = on the card.
