Questions & Answers about Denne opgave er nem for ham, men svær for mig.
Why does the sentence use ham instead of han?
In Danish, ham is the object form (accusative) of han, which is the subject form. Since you are referring to him (direct object) and not he (subject), you use ham.
What role does for play here?
In this context, for indicates that something is easy or difficult for someone. It's part of a common Danish construction to express that a task poses a specific level of difficulty to a particular person.
Why does the sentence say nem for him but svær for me?
Both nem and svær are adjectives describing how easy or hard the task is for each person. Nem means easy, whereas svær means difficult. Danish allows you to use different adjectives in the same sentence to show contrasting experiences.
What is the significance of mig here?
Mig is the object form of jeg (meaning I). You need mig when referring to yourself in an object position, just like ham is for he/him.
