Namesake

Namesake is a term used to characterize a person, place, thing, quality, action, state, or idea that has the same, or a similar, name to another. In the United States, the term is often used for a person or thing actually named after, rather than merely sharing the name of another. For example, if a person, place, or thing is named after another person, place, or thing, then the name target is said to be the namesake of the name source.
