The Niuatoputapu languague was a Polynesian language and the indigenous language of the people of Niuatoputapu, Tonga and possibly Tafahi, Tonga due to its close proximity. Sometime between the 18th to 19th century, it became extinct and its use was replaced by modern Tongan, although small remnants of the old Niuatoputapu language can still be heard in the Tongan language spoken on Niuatoputapu and Tafahi today, as well as in the islands' geographic features. For example, the islet of Nukuseilala appears to use the old Niuatoputapu and modern Samoan pronunciation of "seilala" instead of the modern Tongan "heilala".
