Eponyms are commonly used for time periods, places, innovations, biological nomenclature, astronomical objects, works of art and media, and tribal names.
The term eponym[2][3] functions in multiple related ways, all based on an explicit relationship between two named things.
Eponym may refer to a person – or, less commonly,[3] a place or thing – for which someone or something is, or is believed to be, named.
The word "eponym" can also refer 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).
