There's a video where Eddie Izzard speaks Old English to a speaker of Frisian to demonstrate.
As a Norwegian speaker, I can also pick up much of that dialogue without the subtitles (though I have the advantage of also speaking passable German)
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.
Creoles are defined as languages emerging from pidgins, which themselves are often simplified forms of speech that allow linguistically separate groups to communicate. English is not that. It has an unbroken line of native speakers whose usage gradually evolved, while maintaining a system of complex syntactic rules as well as a literature.
