Question

taboo 【taboo】n.禁忌；禁止Eating human flesh is a taboo in civilized countries.在文明的国度里，吃人肉是被禁止的。

Accepted Answer

[tə'buː] 
tabooan inhibition or ban resulting from social custom or emotional aversion
Something considered taboo is naughty, something society considers a no-no. For example, it is taboo to ask people how much money they earn or about their sex lives.
Taboo is one of those rare words in the English language that doesn't have Greek or Latin or French roots, coming instead from the South Pacific Islands in the eighteenth century via the explorer Captain Cook. For many islanders some things were tabu, meaning not only could they not be done but they could not be talked about either for risk of offending the Gods. This latter meaning still applies today (minus the spiritual underpinning), when we say that certain subjects are "taboo," meaning off-limits for discussion.
