Tuvaluan often called Tuvalu - is a Polynesian language of or closely related to the Ellicean group spoken in Tuvalu. It is more or less distantly related to all other Polynesian languages, such as Hawaiian, Māori, Tahitian, Samoan, and Tongan, and most closely related to the languages spoken on the Polynesian Outliers in Micronesia and Northern and Central Melanesia. Tuvaluan has borrowed considerably from Samoan, the language of Christian missionaries in the late 19th and early 20th centuries.
