Hi and thanks for all your work. This is a good breakdown however I still remain confused when two nouns don't require - de- between them
For example in a book I'm reading " el êpico fracas de Arturo Zamora" Theres a part that that says
Consejo ciudadano. ( citizen council)
This isn't the first time two nouns are next to each other without a " De" inbetween but I don't see the difference between this and something like
La sopa de Pollo
