"Landet ønsker en forening" could have been used to describe west, or east germany until 1990.
It would not be the correct word to use to describe something political with :)
Becuse it is not proper English. "An" is used in front of the words that start with a vowel PHONETICALLY. An hour, an apple. While "union" phonetically starts with a consonant j [ˈjuːnjən]. So it is always "a union".
I only mind not accepting it because I've made much bigger mistakes that were accepted. And this only shows my lack of english knowledge, not danish
