Fantastic summation — much easier to understand than the article itself or the referenced Wikipedia pages.

In two short paragraphs I learned a ton about the distinctions between pidgins, creoles, and ("full"?) languages, in addition to how languages evolve in both subcultures and ("dominant"?) cultures.

I can now apply this knowledge in the context of the Louisiana Creole population, the name of which has previously served to confuse me as to the definition of "creole", as well as other creole languages and populations in the Caribbean.
