I'm sorry I can't formulate my question in German yet. I'm still doing my best to learn. So I'll ask in English anyway because I really need an answer.
I was reading this story (https://www.thegermanproject.com/stories/chicken-little) and this particular sentence got me thinking why ganz have no declension.
Er ist weder groß noch klein. Er ist weder dick noch dünn. Er ist weder schlau noch dumm. Henry Hühnchen ist ein ganz normales Huhn.
I know that adjectives with sein become predicative complements and the adjectives receive no declension. But why does normales have -es?
and right after that something again appeared.
An einem ganz normalen Morgen isst Henry Hühnchen in der Küche sein Frühstück. Er mag Toast mit Butter und Kaffee mit Sahne.
ganz is also without any declension and normales have (-es) but now there is no sein. So NOW I have no excuse (and no idea) either.
I looked into double adjectives. But it seems they all have to receive a declension. So what's going on here?
A little help here? Am I missing something? Is there a grammatical rule I am not aware of?
