An Eponym is a person or thing for whom something is named, or believed to be named, or the name itself. For example, Elizabeth I of England is the eponym of the Elizabethan era. Genericized trademarks such as aspirin, heroin and thermos may also become eponyms. The derivative adjectives eponymous and eponymic refer to the person or thing for whom something is named, as in “the eponymous founder of the Ford Motor Company”. Recent usage, especially in the recorded-music industry, also allows eponymous to mean “named after its central character or creator”.
