Explain the word taboo

Word taboo, also called taboo language, language taboo or linguistic taboo is a kind of taboo that involves restricting the use of words or other parts of language due to social constraints. This may be due to a taboo on specific parts of the language itself (such as certain words, or sounds), or due to the need to avoid a taboo topic. The taboo against naming the dead in parts of the world is an example.
