Questions & Answers about Glemte han det her rejsekort hjemme?
Why use det her instead of dette for "this"?
Both mean "this," but det her is the natural choice in everyday spoken Danish. Dette sounds more formal and is mostly used in writing.
Why is it det her and not den her?
The phrase has to match the gender of the noun. Rejsekort is a compound noun, and in Danish, the final part of a compound dictates the gender. Because it is et kort (a card), the whole word takes the neuter form det her.
I often mix up hjem and hjemme. Why is hjemme the correct choice here?
You use hjemme when there is no movement, meaning someone or something is stationary "at home." You use hjem when there is a direction of travel, like going "homeward." Since the card was left sitting at the house, hjemme is correct.
