Taboo

A taboo is a vehement prohibition of an action based on the belief that such behavior is either too sacred or too accursed for ordinary individuals to undertake, under threat of supernatural punishment. Such prohibitions are present in virtually all societies. The word has been somewhat expanded in the social sciences to strong prohibitions relating to any area of human activity or custom that is sacred or forbidden based on moral judgment and religious beliefs. "Breaking a taboo" is usually considered objectionable by society in general, not merely a subset of a culture.

Etymology

The term "taboo" comes from the Tongan tapu or Fijian tabu ("prohibited", "disallowed", "forbidden"), related among others to the Maori tapu, Hawaiian kapu, Malagasy fady. Its English use dates to 1777 when the British explorer James Cook visited Tonga. Describing the cultural practices of the Tongans, he wrote:

The term was translated to him as "consecrated, inviolable, forbidden, unclean or cursed".Tabu itself has been derived from alleged Tongan morphemes ta ("mark") and bu ("especially"), but this may be a folk etymology (note that Tongan does not actually have a phoneme /b/), and tapu is usually treated as a unitary, non-compound word inherited from Proto-Polynesian *tapu, in turn inherited from Proto-Oceanic *tabu, with the reconstructed meaning "sacred, forbidden". In its current use on Tonga, the word tapu means "sacred" or "holy", often in the sense of being restricted or protected by custom or law. On the main island, the word is often appended to the end of "Tonga" as Tongatapu, here meaning "Sacred South" rather than "Forbidden South".
