«bok» or «bøk»? I'm self-taught in learning Norwegian, and the app Duolingo (which I use) used «bøk» initially for the word "book". I assumed that was the way to write it until I saw them sometimes using «bok». However, I continued using «bøk» for my answers and it never counted it wrong, but one time I tried using «bok» and it counted it wrong. So I was wondering if it's 1) a bug in the app, 2) you can use either one, or 3) it depends on the situation. As far as I can tell, it's random.
