Maragai is one of the dialects of the Paumotu language. Tuamotuan, Paʻumotu or Paumotu (Tuamotuan: Reʻo Paʻumotu or Reko Paʻumotu) is a Polynesian language spoken by 4,000 people in the Tuamotu archipelago, with an additional 2,000 speakers in Tahiti.
The Tuamotu people today refer to their land as Tuamotu, while referring to themselves and their language as Paʻumotu. Paʻumotu is one of six Polynesian languages spoken in French Polynesia, the other five languages being Tahitian, Marquesan, Mangarevan, Rapa Iti, and the language of the Austral Islands. It is an oral transmission language. The alphabet was brought by the europeans and they wrote Paumotu so that is why it is based on the Latin alphabet.
