Eponym

An eponym is the name of a person or thing, whether real or fictitious, after which a particular place, tribe, era, discovery, or other item is named or thought to be named. One who is referred to as eponymous is someone who gives his or her name to something, e.g., Julian, the eponymous owner of the famous restaurant Julian's Castle. A common nonstandard usage is that something eponymous is named after a particular person, e.g., Julian's eponymous restaurant.

In contemporary English, the term self-titled is often used to mean eponymous in the case of a work with the same name as the person or persons who created it (e.g., the song "Black Sabbath", from the album Black Sabbath, by the band Black Sabbath).

An etiological myth can be a "reverse eponym" in the sense that a legendary character is invented in order to explain a term. This is one example of folk etymology.

History

In different cultures, time periods have often been named after the person who ruled during that period.

• The ancient Greek classic The Odyssey is named after the main character, Odysseus.
• One of the first recorded cases of eponymy occurred in the second millennium BC, when the Assyrians named each year after a high official (limmu).
• In ancient Greece, the eponymous archon was the highest magistrate in Athens. Archons of Athens served a term of one year which took the name of that particular archon (e.g., 594 BC was named for Solon). Later historians provided yet another case of eponymy by referring to the period of Fifth-century Athens as The Age of Pericles after its most influential statesman Pericles.
• In Ancient Rome, one of the two formal ways of indicating a year was to cite the two annual consuls who served in that year. For example, the year we know as 59 BC would have been described as "the consulship of Marcus Calpurnius Bibulus and Gaius Julius Caesar" (although that specific year was known jocularly as "the consulship of Julius and Caesar" because of the insignificance of Caesar's counterpart). Under the empire, the consuls would change as often as every two months, but only the two consuls at the beginning of the year would lend their names to that year.
• During the Christian era, many royal households used eponymous dating by regnal years. The Roman Catholic Church, however, eventually used the Anno Domini dating scheme based on the birth of Christ on both the general public and royalty. The regnal year standard is still used with respect to statutes and law reports published in some parts of the United Kingdom and in some Commonwealth countries (England abandoned this practice in 1963): a statute signed into law in Canada between February 6, 1994 and February 5, 1995 would be dated 43 Elizabeth II, for instance.
• Government administrations or political trends often become eponymous with a government leader. North American examples include the Nixon Era, Trudeaumania, Jeffersonian economics, Jacksonian democracy, McCarthyism, Thatcherism, Kennedy's Camelot, or Reaganomics.
• British monarchs have become eponymous throughout the English speaking world for time periods, fashions, etc. Elizabethan, Edwardian, Georgian, and Victorian, are examples of these.

Other eponyms

• In intellectual property law an eponym can refer to a genericized trademark or brand name, a form of metonymy.
• Both in ancient Greece and independently among the Hebrews, tribes often took the name of a legendary leader (as Achaeus for Achaeans, or Dorus for Dorians). The eponym gave apparent meaning to the mysterious names of tribes, and sometimes, as in the Sons of Noah, provided a primitive attempt at ethnology as well, in the genealogical relationships of eponymous originators.
• Places and towns can also be given an eponymous name through a relationship (real or imagined) to an important figure. Peloponnesus, for instance, was said to derive its name from the Greek god Pelops. In historical times, new towns have often been named (and older communities renamed) after their founders, discoverers, or after notable individuals. Examples include Vancouver, British Columbia, named after the explorer George Vancouver; and Prince Albert, Saskatchewan, originally called Isbister's Settlement but renamed after Queen Victoria's husband and consort in 1866.
• In science and technology, discoveries and innovations are often named after the discoverer (or supposed discoverer) or to honour some other influential workers. Examples are Avogadro's number, the Diesel engine, meitnerium, Alzheimer's disease, and the Apgar score. For a discussion of the process see Stigler's law of eponymy.
• In (modern) art
  • Some books, films, video games, and TV shows have one or more eponymous principal characters: Robinson Crusoe, the Harry Potter series, The Legend of Zelda series, I Love Lucy, for example.
  • The term is also applied to music, usually with regard to record titles. For example, Blur's 1997 album was also titled Blur. Bad Company's first album Bad Company released in 1974 is another example that also contained a track that was a Rock Radio favourite of the same name, "Bad Company". Many other artists and bands have also served as eponyms of albums or singles, usually as their debut or second release. Some bands, such as the Tindersticks, Metallica, Led Zeppelin, Crowded House, Van Halen, Duran Duran, Bang Camaro, Santana, Living in a Box, and the Ramones, have released more than one and are thus referred to in other ways, including number and album art (e.g., The Blue Album). Peter Gabriel's first four long-play releases were all such (though the fourth was given a title for its US release). Another more common term is the self-titled album. The band R.E.M. titled their 1988 compilation CD Eponymous as a joke. Brazilian artists usually self-title their albums; almost all the annual Roberto Carlos albums are eponymous. Self-titled albums are often indicated with the abbreviation "s/t," e.g., "They Might Be Giants (s/t)"

Orthographic conventions

Capitalized versus lowercase

• Because proper nouns are capitalized in English, the usual default for eponyms is to capitalize the eponymous part of a term. The common-noun part is not capitalized. For example, in Parkinson disease (named after James Parkinson), Parkinson is capitalized, but disease is not.
• However, some eponymous adjectives are nowadays entered in many dictionaries as lowercase when they have evolved a common status, no longer deriving their meaning from the proper-noun origin.^[1] For example, Herculean when referring to Hercules himself, but often herculean when referring to the figurative, generalized extension sense;^[1] and quixotic and diesel engine [lowercase only].^[1][2] For any given term, one dictionary may enter only lowercase or only cap, whereas other dictionaries may recognize the capitalized version as a variant, either equally common as, or less common than, the first-listed styling (marked with labels such as "or", "also", "often", or "sometimes"). For examples, see the comparison table below.

Genitive versus attributive

• English can use either genitive case or attributive position to indicate the adjectival nature of the eponymous part of the term. (In other words, that part may be either possessive or nonpossessive.) Thus Parkinson's disease and Parkinson disease are both acceptable. Medical dictionaries have been shifting toward nonpossessive styling in recent decades. Thus Parkinson disease is more likely to be used in the latest medical literature (especially in postprints) than is Parkinson's disease.

National varieties of English

• American and British English spelling differences can occasionally apply to eponyms. For example, American style would typically be cesarean section, whereas British style would typically be caesarean section (or cæsarean section [with digraph]).
