Wallisian, or ʻUvean (Wallisian: Fakaʻuvea), is the Polynesian language spoken on Wallis Island (also known as ʻUvea). The language is also known as East Uvean to distinguish it from the related West Uvean language spoken on the outlier island of Ouvéa near New Caledonia. The latter island was colonised from Wallis Island in the 18th century.
Indigenous to Wallis island, the language is also spoken in New Caledonia since the 1950s due to a migration of many Wallisians (especially in Nouméa, Dumbéa, La Foa, and Mont Dore). According to the CIA World Factbook, it had 7,660 speakers in 2015. However, Livingston (2016) states that the actual number of speakers is much higher (around 20,000), albeit difficult to count precisely.
