Taboo

In a group or society, a taboo is something that is not acceptable to talk about or do. An activity or behavior can be taboo in one culture, but not in another. Some things like cannibalism and sexual relationships between siblings are taboo in almost all societies. Sometimes even talking about taboos is taboo. Some taboos may also be against the law, and people who break them may be punished. Breaking taboos can seem rude, and can cause embarrassment or shame.
Origins of the word
The English word "taboo" comes from the Tongan word tapu or the Fijian word tabu. These words usually mean "not allowed", or "forbidden". In its current use in Tonga, the word tapu also translates to "sacred" or "holy", this means something that is protected by custom or by law. For example, the main island in the Kingdom of Tonga, where the capital Nuku'alofa is located and most of the population resides, is called "Tongatapu".
Its first recorded use in English dates back to 1777. An English explorer, Captain James Cook, went to a place he named "the Friendly Islands" (now Tonga). Writing about the Tongans, he wrote:
Some Solomon Islanders say that their languages have a word tabu (said like "ta-boo") that means "holy." This word refers to places in the bush where holy spirits live. Local customs say that nobody should disturb these places unless a ceremony or ritual is taking place. As taboo, they are places that should not be touched.
Common taboos
Many world religions have taboos about food. Islam and Judaism both say there are some foods which people should never eat. A halal diet does not include any of the foods that are taboo in Islam. A kosher diet does not include any of the foods that are taboo in Judaism. Other religions say that people should be vegetarians. In these religions, eating meat is taboo. Many societies also have taboos about food. For example, cannibalism is taboo in most societies in the world.
Some sexual activities, gender roles, and relationships are taboo in many religions, societies, and cultures. For example, fornication, adultery, endogamy violations, miscegenation, homosexuality, incest, bestiality, pedophilia, necrophilia and other paraphilias are taboo in many groups.
In many societies, performing bodily functions in public is taboo. Taboo activities in public might include burping, flatulence, defecation, urination, masturbation, nosepicking, and spitting. In some societies, menstruation is taboo, and women are expected not to talk about it in public.
Some religions say that certain types of genitalia are taboo. For example, Judaism says that boys should be circumcised. In some societies, having sex reassignment surgery is taboo.
Pornography, nudity, drug addiction, alcoholism, slavery, and vulgarity are taboo in many societies. Some cultures see certain gestures as taboo.
In some groups and societies, talking about race or racism is taboo.
Origin
There are two major theories about why taboos exist. The ''Anthropological approach'' says that taboos are the result of history and culture. The ''Psychoanalytical approach'' says there are psychological reasons for why taboos exist.
Anthropological approach
The anthropological approach says that taboos are the result of history and certain cultural experiences. Steven Pinker, A psychologist and writer, says that taboos have developed culturally from more basic instincts. He thinks that humans have a reflex to feel disgust when they see some things that carry disease (including dead bodies). He says that people created taboos regarding the dead because of this natural disgust for dead bodies. He thinks that some actions can also cause this reflex of disgust. He says many people have a reflex of disgust about incest (sexual relationships between family members). For this reason, taboos about incest developed.
Psychoanalytical approach
The psychoanalytical approach says that taboos exist because of people's unconscious thoughts and feelings. For example, Sigmund Freud thought that children naturally have sexual desires towards family members. In his book ''Totem and Taboo,'' Freud wrote that taboos about incest developed to make sure people would not act on these sexual desires. Freud thought that incest and patricide are the only "universal" taboos (meaning these behaviors are taboo in almost all societies and cultures). He said that these taboos formed the basis of modern societies.
