Hi Yorlyee.
When the Bounty mutineers and their Polynesian wives were thrown together on Pitcairn they took elements from one anothers languages to develop a new language, they brought this amalgam of 18th century English and Polynesian with then when they migrated to Norfolk Island in 1856.
To this day ,when they are amangst themselves, they use this language, called simply "Norfolk".. As they also speak English, it would be inappropriate to address them in their own dialect. I can if you want give you a few phrases to give you a "taste" of what it sounds like!
