Avoiuli (from Raga avoi "talk about" and uli "draw" or "paint") is a writing system used by the Turaga indigenous movement on Pentecost Island in Vanuatu. It was devised by Chief Viraleo Boborenvanua over a 14-year period, based on designs found in traditional sand drawings, and intended as a native alternative to the Western alphabet. It is used mainly for writing in the area's native Raga language, although it can also be used for other languages including Apma, Bislama and English.
