Example of Taboo

The concept of 'taboo' is taken from Polynesian language usage. 'Tabu' is the Fijian word which has similar sounding equivalents in Hawaiian 'kapu' and Tahitian 'tapu'. It means a state of being forbidden, prohibited, sacred, off limits in a religious context. In modern English usage it has retained the same basic meaning, but it's commonly used as a noun.
