Things native English speakers know, but don’t know we know:

Adjectives in English absolutely have to be in the following order:

1. Opinion;
2. Size;
3. Age;
4. Shape;
5. Colour;
6. Origin;
7. Material;
8. Purpose Noun.

So you can have a lovely little old rectangular green French silver carving knife.

But if you mess with the above word order you’ll sound like a maniac.

It’s an odd thing that every English speaker uses that list, but almost none of us could write it out.

And as size comes before colour, green great dragons can’t exist!!!!!
