Aitu

In Polynesian languages the word aitu refers to ghosts or spirits, often malevolent. The word is common to many languages of Western and Eastern Polynesia. In the mythology of Tonga, for example, ʻaitu or ʻeitu are lesser gods, many being patrons of specific villages and families. They often take the form of plants or animals, and are often more cruel than other gods. These trouble-making gods are regarded as having come from Sāmoa. The Tongan word tangi lauʻaitu means to cry from grief, to lament.
