"Timeless" refers to something that is not affected by the passage of time, remaining relevant and valuable across different eras. This concept can apply to various fields, including art, literature, fashion, and music, where certain works or styles continue to resonate with audiences long after their creation. In popular culture, the term is often used to describe classic films, iconic songs, or enduring fashion trends that maintain their appeal. For example, Shakespeare's plays and Beethoven's symphonies are considered timeless because they continue to be studied and enjoyed, reflecting universal themes and emotions that transcend generations.
