Maritime Polynesian Pidgin

Maritime Polynesian Pidgin was a Polynesian-based pidgin that was the main contact language for European exploratory and whaling expeditions to the Pacific during the - centuries. It would later be supplanted in that role by Pidgin English, which developed after the 1870s.
According to Drechsel, some segments of the Tahitian, Māori and Hawaiian languages were grammatically similar and mutually intelligible. With European exploration, these forms would have merged into a regional contact language that would later be used for trade with Polynesian populations, and also on board ships, between European and Polynesian members of the crews, in preference to English.
