Translation:A black book.
Zwartboek... The name of an excellent Dutch WWII movie!
Zwarte Boeken is an hilarious british sitcom.
For my fellow mobile users: there are actually rules in the desktop version of Duolingo. You just have to open the lesson from the site, the grammar is at the bottom.
Thanks! That should help me a good deal
Can someone please help me understand why it is "Enn grijze muis", but it's "Een zwart boek"?
Adjectives before het-words (like boek), don't end on -e.
De zwarte muis
Een zwarte muis
Het zwarte boek
Een zwart boek
Is there an "easy" way to remember which words are Het and which are De? It seems pretty random to me.
As a native speaker, it seems random to me. This post gives some guidelines: https://www.duolingo.com/comment/3732938.
If anyone has trouble opening that link like I did, try it without the "." https://www.duolingo.com/comment/3732938
And see here for the full explanation on adjectives.
