Tuvaluan is a Polynesian language spoken by about ten thousand people in the independent nation of Tuvalu, consisting of nine small islands in the south-central Pacific, and small groups of Tuvaluan migrants in Australia, Fiji, Kiribati, the Marshall Islands, Nauru, New Zealand and the USA.
On one of the Tuvaluan islands, Nui, a Micronesian dialect of Kiribati is spoken. However, most Nui islanders are now bilingual in their vernacular and in Tuvaluan.
Within the Polynesian family of languages Tuvaluan belongs to the so-called Samoic-Outlier group, and is most closely related to the languages of Tokelau, Futuna and Samoa, but also - though more distantly - to Tongan, Tahitian, Hawaiian and Maori.
