Current scholarly opinion holds that a trade language probably existed before European contact, which began "morphing" into the more familiar Chinook Jargon in the late 1790s, notably at a dinner party at Nootka Sound where Capts Vancouver and Bodega y Quadra were entertained by Chief Maquinna and his brother Callicum performing a theatrical using mock English and mock Spanish words and mimicry of European dress and mannerisms. There evidently was a Jargon in use in the Queen Charlotte, but this "Haida Jargon" is not known to have shared anything in common with Chinook Jargon, or with the Nooktan-Chinookan "proto-jargon" which is its main foundation.
