Tapu
A Polynesian term for what is set apart as sacred or restricted, the source of the English word taboo.
Also: tabu, kapu, tambu
Tapu, in Maori, Tongan, Hawaiian (kapu) and related languages, marks a person, place, object or time as sacred and restricted, with consequences for crossing the line. It is bound up with rank: a chief's body, a burial ground or a fishing ground may be tapu. Its opposite is noa, the ordinary and safe. The word entered English through Captain James Cook's accounts of Tonga in the 1770s as taboo. Many Pacific communities still use tapu in daily life, for example for a rahui, a temporary ban on a stretch of sea or forest. The English word has since drifted far from the meaning it holds in these languages.
