I think the traditional difference between cobbles and a cobblestone something is the same distinction as pebbles vs a pebbledash something.
A pebble is of course a small rock. Pebbledash describes the decorative finish — which is made of pebbles and other material like cement or concrete — on some physical thing. You would say “my new house has pebbledash walls” or just by itself as a shorthand where it implies an unsaid word: “the pebbledash [finish] on this property gives it a delightfully vintage feel!”
So historically speaking, cobblestone describes a type of surface finish made of cobbles, and the two words have been quite separate.
Aerial is a fun one too. An antenna has components such as bolts and fixtures and junction boxes, but most prominently it will have a wire or other metal object that is thrust into the air: that is to to say a component that is aerial, or the aerial component.
Once I learned that distinction, saying “aerial” instead of the more precise “antenna” seems very quaint, like saying “wireless” for radio or “pianoforte” for piano. It’s not exactly the same as cobbles being used in cobblestone finishes, but they are interesting examples of nouns and adjectives merging into each other.
