Tabu, or taboo, refers to a social or cultural prohibition against certain behaviors, practices, or discussions. These restrictions often arise from beliefs, customs, or religious practices, and they can vary significantly between different societies. Violating a taboo can lead to social ostracism or punishment, as it challenges the norms and values of a community. Common examples of taboos include topics like death, incest, and cannibalism. In many cultures, discussing these subjects openly is considered inappropriate or offensive. Understanding taboos is essential for navigating social interactions and respecting cultural differences.
