Placeholder names are intentionally overly generic and ambiguous terms referring to things, places, or people, the names of which or of whom do not actually exist; are
temporarily forgotten, or are unimportant; or in order to avoid
stigmatization, or because they are unknowable and/or unpredictable given the context of their discussion; to de-emphasize in which event the precise specification thereof is otherwise impossible, or to deliberately expunge.[1]
These
placeholders typically function
grammatically as
nouns and can be used for people (e.g. John Doe, Jane Doe), objects (e.g. widget), locations ("Main Street"), or places (e.g. Anytown, USA). They share a property with
pronouns because their
referents must be supplied by context; but, unlike a pronoun, they may be used with no referent—the important part of the communication is not the thing nominally referred to by the placeholder, but the context in which the placeholder occurs.
In their Dictionary of American Slang (1960),
Stuart Berg Flexner and Harold Wentworth use the term kadigan for placeholder words. They define "kadigan" as a synonym for thingamajig. The term may have originated with
Willard R. Espy, though others, such as David Annis, also used it (or cadigans) in their writing. Its
etymology is obscure—Flexner and Wentworth related it to the generic word gin for
engine (as in the cotton gin). It may also relate to the
IrishsurnameCadigan.
Hypernyms (words for generic categories, such as "flower" for
tulips and
roses) may also be used in this function of a placeholder, but they are not considered to be kadigans.
Examples
Placeholder words exist in a highly informal
register of the English language. In formal speech and writing, words like accessory, paraphernalia, artifact, instrument, or utensil are preferred; these words serve substantially the same function, but differ in connotation.
Most of these words can be documented in at least the 19th century.
Edgar Allan Poe wrote a short story entitled "The Literary Life of Thingum Bob, Esq.", showing that particular form to be in familiar use in the United States in the 1840s. In
Gilbert and Sullivan's The Mikado,
W. S. Gilbert makes the Lord High Executioner sing of a "little list" which includes:
... apologetic statesmen of a compromising kind,
Such as: What d'ye call him: Thing'em-bob, and likewise: Never-mind,
and 'St: 'st: 'st: and What's-his-name, and also You-know-who:
The task of filling up the blanks I'd rather leave to you.
Some fields have their own specific placeholder terminology. For example, "
widget" in economics, engineering and electronics, or "
Blackacre" and "
John Doe" or "Jane Doe" in law. "
X-ray" was originally a placeholder name for an unexplained phenomenon.
Companies and organizations
"Ace" and "Acme" were popular in company names as positioning words in alphabetical directories. They were generic, laudatory of whatever products they were used to promote and appeared at the beginning of most alpha-sorted lists. ("Acme" is a regular English word from the
Ancient Greekἀκμή, akme meaning summit, highest point, extremity or peak, and thus sometimes used for "best".) A well-known example of "Acme" as a placeholder name is the
Acme Corporation, whose products are often seen in the
Wile E. Coyote and the Road Runner cartoons.
"Mom and Pop" (in the United States) are occasional placeholders for the individual owners of a generic small family-owned business
"Advent corporation" is a term used by lawyers to describe an as yet unnamed corporation, while legal incorporation documents are being prepared. In the case of
Advent Corporation, founder Henry Kloss decided to adopt this placeholder name as the formal legal name of his new company.
"
NewCo" or "Newco" is used in a similar way in the UK for an as-yet-unnamed company.

Morley are often used in television and cinema as placeholders to avoid unintended
product placement. "Brand X" has been used in television advertisements as a
generic brand representing any other brand than the one being advertised.
"XYZ Widget Company" has long been used in business and economics textbooks as a sample company. Also used as engraving text example on items such as plaques, trophy plates, etc. Occasionally appears on customizable promotional materials including stationery templates, business cards, advertising signage, cups, backpacks, and other "swag" samples.

Domain names
Certain
domain names in the format example.tld (such as example.com, example.net, and example.org) are officially reserved as placeholders for the purpose of presentation.[5] Various example
reserved IP addresses exist in

IPv6, such as 192.0.2.0 in IPv4 documentation and 2001:db8:: in IPv6 documentation.
Geographical locations
Placeholders such as Main Street, Your County, and Anytown are often used in sample mailing addresses. Ruritania is commonly used as a placeholder country.

Legal
In
ancient Roman law, the names Aulus Agerius and Numerius Negidius were used to represent the plaintiff and the defendant. The names were both wordplays, respectively meaning "[I] set in motion" and "[I] refuse to pay". The model instruction to judges for civil suits began with si paret Numerium Negidium Aulo Agerio sestertium decem milia dare oportere, meaning "if [it] appears that Numerius Negidius ought to pay Aulus Agerius ten thousand
sesterces...".
In the
United States and
Canada, John Doe and the variations Jane Doe (for females) and John Roe or Richard Roe (for a second party): used in legal action and cases when the true identity of a person is unknown or must be withheld for legal reasons. Jane Roe was used for the then-unidentified plaintiff (
Norma Leah McCorvey) in one of the most famous legal cases in United States history, Roe v. Wade. These parties also appear in the
legal fictions of the action in
ejectment, which was the usual proceeding to
quiet title to
real property under
common law pleading.
Mopery: used in informal legal discussions as a placeholder for some infraction, when the exact nature of the infraction is not important.[citation needed]
Blackacre and its neighbors Whiteacre, Greenacre, Brownacre, Greyacre, Pinkacre, etc. are used as placeholders for parcels of real property, usually on Law School examinations and the several State Bar Exams. They are sometimes located in Acre County in the fictional
State of Franklin.[citation needed]
Fnu Lnu is used by authorities to identify unknown suspects, the name being an
acronym for First Name Unknown, Last Name Unknown. If a person's first name is known but not the last, or vice versa, they may be called [real name] Lnu or Fnu [real name], and an unidentified person may be Fnu Lnu. For example, a former interpreter for the
United Statesmilitary was charged as "FNU LNU",[10] and a
mute man whose identity could not be determined was arrested and charged with burglary in
Harris County, Texas under the name "FNU-LNU" (charges were later dropped because authorities could not communicate with the man).[11]Fnu-Lnu conjunctions may also be used if the person has only a single name, as in
Indonesian names. The name has been considered a source of humor when Fnu Lnu has been mistaken for the actual name of a person.[12]
X ben X (
lit.'X, son of X',
Arabic: إكس بن إكس or سين بن سين) is used in
Morocco by health and
judicial authorities in cases where an individual's identity cannot be determined. These cases include amnesiacs, suspects, hospital patients, and homeless people.[13][14] In 2009, 80,000 abandoned orphans had the placeholder name of X ben X and 100 unidentified bodies are buried each year in Morocco under this status.[15]
Medicine
St. Elsewhere is often used as a placeholder name for any regional hospital or other care facility from which an admitted patient was referred. The medical slang is honored in the name of the 1980s television show of the
same name.

pejorative.
Element names from the
periodic table are used in some hospitals as a placeholder for patient names, ex. Francium Male.[16]
Military
Often used in example names and addresses to indicate to the serviceman where to put his own details.
In the US Army and Air Force, Private (or Airman) Tentpeg and Snuffy are commonly used in examples (to explain various procedures) or cautionary tales. In the Marine Corps, Lance Corporal Schmuckatelli serves the same purpose.[17]

Placeholder telephone numbers are often allocated from ranges such as 555 (where +1-[area code]-555-1212 is reserved in North America for
directory assistance applications) to avoid generating
misdialled calls to working numbers. In the United Kingdom,
Ofcom has set aside a range of numbers in larger geographic area codes, as well as fictional area code 01632 (0632 having been the code for
Newcastle upon Tyne until replaced by 091 in the 1980s), for dramatic use.[18]
Common placeholders for
postcodes in Canada include A1A 1A1 (a real postal code for Lower Battery Road,

Santa's workshop). In the United States, the
ZIP Code 90210 (from TV series
Beverly Hills 90210) is frequently used. Numeric codes with repeated or sequential digits like 12345 (a
General Electric plant in
Schenectady, New York), or 99999-9999 (unused but in a
prefix range for the vicinity of
Ketchikan, Alaska) may also appear. 00000, which lies in an unused prefix range, can be used without confusion.
In computing, some
magic numbers (and other uses of hexadecimal numbers) apply
hexspeak to create memorable hexadecimal values, such as 0xdeadbeef.
In chemistry, tentative or hypothetical elements are assigned provisional names until their existence is confirmed by
IUPAC. Historically, this placeholder name would follow
Mendeleev's nomenclature; since the
Transfermium wars, however, the consensus has been to assign a
systematic element name based on the element's atomic number.[19] Examples of these systems in use would be "ekasilicon" (
germanium) and "ununseptium" (
tennessine) respectively.
Similarly, the name "
unobtainium" is frequently used for a material of highly desired characteristics which does not exist or which would be prohibitively expensive to mine, procure or synthesize.
