'' (after the Roman emperor Caligula). Common name, Common names can also be named after a person. Later, people may decide that they do not wish to memorialize a particular person, resulting in efforts to change a long-standing name. As debating each individual name is time-consuming, the American Ornithological Society announced in 2024 that they would establish new common names for all birds in North America that had previously been named after a person, without regard to whether modern culture would judge the person well or poorly. ** Relatedly, medical terminology, biomedical terminology uses lists of medical eponyms, many eponymous terms, and many also have noneponymous synonyms. ** Many astronomical objects are named after their discoverer or another person. * In art: ** Plays, books, and other forms of entertainment may have eponymous names, such as the ancient Greek epic ''The Odyssey'', derived from its principal character, Odysseus, and the novel ''Robinson Crusoe''. ** The term is also used in the music industry, usually with regard to record titles, where it is prevalent and leads to confusion. For example, Bad Company (band), Bad Company's first album was entitled ''Bad Company (album), Bad Company'' and contained a popular song named "Bad Company (song), Bad Company". Parodying this, the band R.E.M. titled a 1988 compilation album ''Eponymous (album), Eponymous''. One especially convoluted case of eponyms is the 1969 song "Black Sabbath (song), Black Sabbath", named after the 1963 movie Black Sabbath (film), ''Black Sabbath''; the band that wrote the song changed their name to Black Sabbath and released it on the album Black Sabbath (album), ''Black Sabbath''. * In tribal antiquity, both in ancient Greece and independently among the Hebrews, tribes often took the name of a legendary leader (as Achaeus, son of Xuthus, Achaeus for Achaeans (tribe), 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.

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. When used as proper adjectives they are normally capitalized, for example

, Shakespearean, and Kafkaesque. * However, some eponymous adjectives and noun adjuncts 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 only]. 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", 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 James Parkinson), ''Parkinson'' is capitalized, but ''disease'' is not. In addition, the adjectival form, where one exists, is usually lowercased for medical terms (thus ''parkinsonian'' although ''Parkinson disease''), and gram-negative bacteria, gram-negative, gram-positive bacteria, gram-positive although Gram stain. 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 ''Platonism, Platonic'' 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 of eponym orthographic styling, 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 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 postprints) 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, Medical Subject Headings (MeSH) of the United States National Library of Medicine, United States National Library of Medicine (NLM) use
"cesarean section"
, while the also US-published ''Saunders Comprehensive Veterinary Dictionary'' use
"caesarean"
. The online versions of th
''Merriam-Webster Dictionary''
an
''American Heritage Dictionary''
list "cesarean" first and other spellings as "variants", an etymologically anhistorical position.
