Reddit mentions of The Voices of Eden: A History of Hawaiian Language Studies

Pidgin is a legitimate language on its own, although it is certainly based on and influenced by English. It’s a creole language, not a dialect. It’s not actually a pidgin because those are by definition not spoken by anyone as a first language, whereas Pidgin is a complete language learned by people from birth.

Here’s a web page from UH on Pidgin. Notice the term “Hawaiʻi Creole” and not “Hawaiian Creole”; it’s from Hawaiʻi but not really based on Hawaiian. There’s also a paper on Pidgin and education in Hawaiʻi by Da Pidgin Coup, a group of linguists at the University of Hawaiʻi at Mānoa who study Pidgin.

Sakoda and Siegel have a nice little introductory grammar. The first couple chapters are good background info that addresses your questions and more. If you’re in Hawaiʻi you should be able to find this in any of the UH bookstores as well as some other places. Try read em.

Al Schütz also has an excellent book Voices of Eden which is a detailed history of the Hawaiian language. It includes some discussion of Pidgin and the earlier Hawaiian-based pidgin which was replaced by Pidgin.
