An eponym is a person, place, or thing after whom or which someone or something is, or is believed to be, named. The adjectives derived from eponym include eponymous and eponymic.

Word usage

The term eponym[2][3] functions in multiple related ways, all based on an explicit relationship between two named things. A person, place, or thing named after a particular person share an eponymous relationship. In this way, Elizabeth I of England is the eponym of the Elizabethan era. When Henry Ford is referred to as "the eponymous founder of the Ford Motor Company", his surname "Ford" serves as the eponym. The term also refers to the title character of a fictional work (such as Rocky Balboa of the Rocky film series), as well as to self-titled works named after their creators (such as the album The Doors by the band the Doors). Walt Disney created the eponymous Walt Disney Company, with his name similarly extended to theme parks such as Disneyland.[4][5][6][7]
