"Vi spiser orange appelsiner", "orange" is only a color and "appelsin" is only a fruit.
Here appelsiner is plural, meaning that you add an -e to the end of the colour
You've never been to Brazil. All the oranges in Brazil are green, so I have no trouble believing that Danish oranges are all yellow. :)
Why is there no "det,den or de" before gule appelsiner? This is such just because gule appelsiner are in indefinite form?
When you have an adjective (like yellow) you put the definite article before the adjective instead of on the end of the noun.
Mange tak sopzeh. It makes more sense to me now. unfortunately am doing most of it on my phone and it doesnt have the notes that the desktop version has so I tend to ask rather silly questions even at level 9!
