Questions & Answers about Det er et virkeligt problem, hvis døren ikke kan åbnes.
Here Det er works like English It is.
Danish very often uses det er to introduce a general statement or evaluation:
- Det er godt = It is good
- Det er et problem = It is a problem
So in this sentence, det does not point to a specific thing in a very concrete way. It simply introduces the statement: It is a real problem...
Because problem is a neuter noun in Danish.
Danish nouns are mainly either:
- common gender: take en
- neuter: take et
So:
- et problem = a problem
This gender also affects the adjective, which is why you get et virkeligt problem.
Because virkelig is agreeing with the neuter noun problem.
In Danish, an adjective usually adds -t when it modifies a singular indefinite neuter noun.
So:
- en virkelig udfordring = a real challenge
- et virkeligt problem = a real problem
That -t is there because of et problem.
