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

Usage of the word
The term eponym( ἐπώνυμος ( a.) given as a name, ( b.) giving one's name to a thing or person, ἐπί upon + ὄνομα, ὄνυμα name) 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 . When 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 of a fictional work (such as 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 ). created the eponymous Walt Disney Company, with his name similarly extended to theme parks such as Walt Disney World. Medical eponymous terms are often called medical eponyms although that usage is .

Periods have often been named after a ruler or other influential figure:
  • One of the first recorded cases of eponymy occurred in the second millennium BC, when the named each year after a high official ( ).
  • In , the was the highest magistrate in . Eponymous archons served a term of one year which took the name of that particular archon (e.g., 594 BC was named after ). 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 .
  • In , the head priest of the Cult of Alexander and the Ptolemies was the eponymous priest after whom years were named.
  • The explains the origins of peoples through individuals who bear their name.

In most cases, the experiences and behavior of the ancestor is meant to indicate the characteristics of the people who take their name.
  • In , one of the two formal ways of indicating a year was to cite the two annual who served in that year. For example, the year we know as 59 BC would have been described as "the consulship of and " (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 , itself eponymous, many royal households used eponymous dating by . The Roman Catholic Church, however, eventually used the 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).
  • Government administrations may become referred to eponymously, such as Kennedy's Camelot and the Nixon Era.
  • British monarchs have become eponymous throughout the English-speaking world for time periods, fashions, etc. , Georgian, , and are examples of these.

Orthographic conventions

Capitalized versus lowercase
  • Because are capitalized in English, the usual default for eponyms is to capitalize the eponymous part of a term. When used as they are normally capitalized, for example , , and .

    (2013). 9781491800751 .
  • However, some eponymous adjectives and 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. For example, Herculean when referring to Hercules himself, but often herculean when referring to the figurative, generalized extension sense; and quixotic and diesel engine lowercase. 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"). The Chicago Manual of Style, in its section "Words derived from proper names",
    (1993). 9780226103891, University of Chicago Press.
    gives some examples of both lowercase and capitalized stylings, including a few terms styled both ways, and says, "Authors and editors must decide for themselves, but whatever choice is made should be followed consistently throughout a work."
  • When the eponym is used together with a noun, the common-noun part is not capitalized (unless it is part of a title or it is the first word in a sentence). For example, in Parkinson disease (named after ), Parkinson is capitalized, but disease is not. In addition, the adjectival form, where one exists, is usually lowercased for medical terms (thus although Parkinson disease),
    (2005). 9781401873745, Delmar Cengage Learning. .
    and gram-negative, gram-positive although .Centers for Disease Control and Prevention. Emerging Infectious Diseases Style Guide. Preferred Usage Uppercase Gram-positive or Gram-negative however are also commonly used in scientific journal articles and publications. In other fields, the eponym derivative is commonly capitalized, for example, Newtonian in physics, and in philosophy (however, use lowercase platonic when describing love). The capitalization is retained after a prefix and hyphen, e.g. non-Newtonian.

For examples, see the comparison table below.

Genitive versus attributive
  • English can use either 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 non-possessive.) Thus Parkinson's disease and Parkinson disease are both acceptable. Medical dictionaries have been shifting toward nonpossessive styling in recent decades., chapter 16: Eponyms. Thus Parkinson disease is more likely to be used in the latest medical literature (especially in ) than Parkinson's disease.

National varieties of English
  • American and British English spelling differences may apply to eponyms. For example, British style would typically be caesarean section, which is also found in American medical publications, but cæsarean section (with a ligature) is sometimes seen in (mostly older) British writing, and cesarean is preferred by American dictionaries and some American medical works.Medical Subject Headings (MeSH) of the United States National Library of Medicine (NLM) uses "cesarean section", while the also US-published Saunders Comprehensive Veterinary Dictionary uses "caesarean". The online versions of the Merriam-Webster Dictionary and American Heritage Dictionary list "cesarean" first and other spellings as "variants", an etymologically anhistorical position.
