Chinook Wawa
Chinook Jargon or Chinook Wawa — wawa meaning "talk" — is a pidgin language that was prevalent in British Columbia and the Pacific Northwest in the 1800s and early 1900s. Its small vocabulary and simplified grammar and sound system made it ideal for communication between diverse communities, especially those engaged in trade. The language is based on Lower Chinook, Nuu-chah-nulth (Nootka), French, English, with some contributions from Salishan, and other Indigenous languages. It is estimated that approximately 100,000 people could speak Chinook Wawa in 1875, and it was used widely in court testimony, newspaper advertising, missionary activity among Indigenous peoples, and everyday conversation from central British Columbia to northern California.
