Not to be confused with the Tuamotu dialect of Puka-Puka in French PolynesiaPukapukan is a Polynesian language that developed in isolation on the island of Pukapuka (Danger Island) in the northern group of the Cook Islands. As a "Samoic Outlier" language with strong links to western Polynesia, Pukapukan is not closely related to any other languages of the Cook Islands, but does manifest substantial borrowing from some East Polynesian source in antiquity.
