Moriori

Moriori, or ta rē Moriori ('the Moriori language'), is a Polynesian language most closely related to New Zealand Māori. It is spoken by the Moriori, the indigenous people of New Zealand's Chatham Islands (Rēkohu in Moriori), an archipelago located east of the South Island. Moriori went extinct as a first language at the turn of the 20th century, but revitalisation attempts are ongoing.

Moriori is a Polynesian language that diverged from Māori dialects after centuries of isolation, while still remaining mutually intelligible. The language has a guttural diction and consistent suppression of terminal vowels, meaning that, unlike in Māori, words may end in consonants.
