"Her shoes are white."
Translation:Hendes sko er hvide.
I am really struggling with Danish adjectives. How do I know which ending to use? Can someone explain in simple terms? I've read duolingo's explanation but still confused.
Simply put, "sko" is plural (shoes), so you must use the plural form of the adjective, in this case hvid becomes "hvide".
Because "sine" along with sin and sit can only be used on the object of a sentence. And can only be used if the object belongs to the subject if the subject is a third person, singular pronoun or noun. "Hun har sine hvide sko" (she has her own white shoes) is different to "Hun har hendes hvide sko" (she has her [someone else's] white shoes)
how can I know if the owner is the same or other person than 'she'? I see no context here which can help me to decide....
Well, in this sentence there is only a subject, and since "sin/sit/sine" only goes with an object it wouldn't be right to have it in this sentence. However, in a sentence like "She has her white shoes" both "Hun har sine hvide sko" and "Hun har hendes hvide sko" should be accepted, if not then report them
