The word 'vestigial' is used to describe something that used to have a purpose or function, but no longer does. It is often used in the context of biology to describe body parts or organs that have become reduced or non-functional over time. For example, the human appendix is considered a vestigial organ because it no longer serves a clear purpose in the body. In everyday language, you might also use the word vestigial to describe something that is no longer needed, such as a vestigial habit or tradition that has lost its relevance.
