Eponymous
"Eponymous" refers to something that is named after a particular person or entity. This term is often used in literature, music, and other creative fields to describe works that share the name of their creator. For example, a book titled "Frankenstein" is eponymous because it is named after its author, "Mary Shelley," and the character within the story.
In a broader context, eponymous can apply to brands or products named after their founders, such as "Ford" automobiles, named after "Henry Ford." This concept highlights the connection between the name and the individual or entity it represents, emphasizing their influence or significance.
