Could we also say "glad" instead of "happy"? As a native English speaker, this is how I am going to remember it.
Correct. Please report it when you find it :)
Danish "glad" covers both English "glad" and "happy".
Though, as a native English speaker as well, I would understand a difference between glad and happy. Glad is being pleased at a result of something (sort of). If someone asks you "how are you" you wouldn't reply "i am glad".
Should be possible, it means the same. If you get an error for it, report it.
After studying mainly Swedish, Danish pronunciation makes my head hurt..
It is weird that it counted 'fond' as a mistake whereas it has given it as an option just a few moments ago... oh, well
phonetically how is glad pronounced? Is sounds like Glow but I dont know if that the voice duo uses or not.
