"The red strawberry is good."
Translation:Die rote Erdbeere ist gut.
Having read the other user comments, and followed the link given, I want to know how as a beginner I am supposed to know what appears to be a complex grammatical issue, and one well beyond this level? Expecting a novice to understand why 'rot' and not 'rote' is basically unhelpful and unfair. I will write the answer down, so I can complete the level, but it will be completion without proper understanding and surely this is the very thing Duolingo should strive to avoid.
Yes, the suffix of adjectives depends on the case:
- die rote Erdbeere - 1. Fall (Nominativ) - Was?
- der roten Erdbeere - 2. Fall (Genitiv) - Wessen?
- der roten Erdbeere - 3. Fall (Dativ) - Wem?
- die rote Erdbeere - 4. Fall (Akkusativ) - Wen?
The suffix of adjectives also depends on gender of the noun:
- ein roter Eimer - male (der)
- eine rote Erdbeere - female (die)
- ein rotes Kleid - neuter (das)
