Is there much of a distance between "elsker" and "er glad i"? Are there situations where you would use one but not the other?
When speaking of love of people: "elsker" is romantic love, while "glad i" is for friends and family. I have seen "elsker" used to describe things that are loved, obviously not romantically.
Tusen takk for forklaringen! :D
I am really glad that they use it correctly here!
why "er du glad i naboene sine" is not correct?
'Sine' can only be used when the subject is 'hun' or 'han' (If I understood it correctly). Since this sentence has 'du' as subject, 'dine' is the correct word to use.
It can also be used when "de" is the subject. It's used for third person pronouns, as well as nouns.
Thanks for the addition!
