eponymous

Etymology

It is borrowed from Ancient Greek ἐπώνυμος (epṓnumos, “given as a name, giving one's name to something”) with the suffix -ous.^[2][3][4][5] The Greek adjective is formed from ἐπί (epí, “upon”) and ὄνυμα (ónuma, “name”), an Aeolic form of ὄνομα (ónoma),^[6][7][2][3] the cognate of name.^[6][5] Etymonline takes it as formed from eponym and -ous,^[8] but the OED dates both words to 1846,^[2] and Dictionary.com calls eponym a back-formation from the adjective.^[9]

Earliest recorded meaning

Giving one's name to something, especially of the mythical figures from whom places or peoples were said to take their names: 1846, in George Grote's History of Greece.^[2][5][3] Etymonline dates it to 1833.^[8]

Semantic evolution

From 1858 it was also used of the magistrate, such as the chief archon at Athens, who gave his name to the year of his office.^[2] Etymonline notes that eponymal has been used in this sense.^[8] In modern use the word mostly refers to the character after whom a book, play or film is named, and to a work named after its central character or its creator, especially a pop album named after the artist.^[10][11] The American Heritage Dictionary records the extended sense of named after something else, illustrated with toys sold under the name of a television programme.^[12]
