Computer scientists andmathematicians often vocalize it asstar (as, for example, intheA* search algorithm orC*-algebra). An asterisk is usually five- or six-pointed inprint and six- or eight-pointed when handwritten, though more complex forms exist. Its most common use is to call out afootnote. It is also often used to censor offensive words.
There are several precursors to the asterisk, which may be unrelated in meaning.[3] A kind of asterisk symbol was in used inice agecave paintings.[4] One hypothesis for the origin of the asterisk used to mark notes is that it stems from the 5000-year-oldSumerian characterdingir,𒀭,[5] though this hypothesis seems to only be based on visual appearance.[6]
Early asterisks seen in the margin of Greek papyrus.
There is also a two-thousand-year-old character used byAristarchus of Samothrace called theasteriskos, which he used when editing Homeric poetry to mark lines that were duplicated.[7]Origen is known to have also used the asteriskos to mark missingHebrew lines from hisHexapla.[8] In the Middle Ages, the asterisk (along with other symbols) was used to emphasize a particular part of text, often linking those parts of the text to a marginal comment.[9] The asterisk was frequently used to indicate footnotes in the era of print media.[10]
When toning downexpletives, asterisks are often used to replace letters. For example, the word "badword" might become "ba***rd", "b*****d", "b******" or even "*******".[11] Vowels tend to be censored with an asterisk more than consonants, but the intelligibility of censored profanities with multiple syllables such as "b*dw*rd" and "b*****d" or "ba****d", or uncommon ones is higher if put in context with surrounding text.[12] Incomics, an entire swear word may be replaced with agrawlix, a string of typographic symbols used to indicate undefined profanity.[13]
In colloquial usage, an asterisk attached to a sportingrecord indicates that it is somehow tainted. This is because results that have been considered dubious or set aside are recorded in the record books with an asterisk rendering to a footnote explaining the reason or reasons for concern.[16] During the first decades of the 21st century, the asterisk came to denote a tainted accomplishment, initially due to its use in North American sports records.[17] This "tainted" usage soon spread to American politics.[18]
The usage of the term in sports arose during the 1961 baseball season in whichRoger Maris of theNew York Yankees was threatening to breakBabe Ruth's 34-year-old single-seasonhome run record. Ruth had amassed 60 home runs in a season with only 154 games, but Maris was playing the first season in the American League's newly expanded 162-game season. Baseball CommissionerFord C. Frick, a friend of Ruth's during the legendary slugger's lifetime, held a press conference to announce his "ruling" that should Maris take longer than 154 games both records would be acknowledged by Major League Baseball, but that some "distinctive mark" [his term][19] be placed next to Maris', which should be listed alongside Ruth's achievement in the "record books". The asterisk as such a mark was suggested at that time byNew York Daily News sportswriterDick Young, not Frick.[19] The reality, however, was that MLB had no direct control over any record books until many years later, and it all was merely a suggestion on Frick's part. Within a few years the controversy died down and all prominent baseball record keepers listed Maris as the single-season record holder for as long as he held the record.[19]
Nevertheless, the stigma of holding a tainted record remained with Maris for many years, and the concept of a real or figurative asterisk denoting less-than-accepted "official" records has become widely used in sports and other competitive endeavors. A 2001TV movie about Maris's record-breaking season was called61* (pronouncedsixty-one asterisk) in reference to the controversy.[20]
Uproar over the integrity of baseball records and whether or not qualifications should be added to them arose again in the late 1990s, when asteroid-fueled power explosion led to the shattering of Maris' record. Even though it was obvious - and later admitted[21] - byMark McGwire that he was heavily on steroids when he hit 70 home runs in 1998, ruling authorities did nothing - to the annoyance of many fans and sportswriters. Three years later self-confessed steroid-userBarry Bonds pushed that record out to 73, and fans once again began to call for an asterisk in the sport's record books.
Fans were especially critical and clamored louder for baseball to act during the 2007 season, as Bonds approached and later brokeHank Aaron's career home run record of 755.[22]
TheHouston Astros' 2017 World Series win was marred after an investigation by MLB revealed the team's involvement in asign-stealing scheme during that season. Fans, appalled by what they perceived to be overly lenient discipline against the Astros players, nicknamed the team the "Houston Asterisks".[23]
It signifies a total number of runs scored by a batsman without losing their wicket; e.g. "107*" means "107not out".
Where only the scores of the two batsmen that are currently in are being shown, an asterisk following a batsman's score indicates that he is due to face the next ball to be delivered.
When written before a player's name on a scorecard, it indicates thecaptain of the team.
It is also used on television when giving a career statistic during a match. For example, "47*" in a number of matches column means that the current game is the player's 47th.
In somecommand line interfaces, such as theUnix shell andMicrosoft'sCMD, the asterisk is thewildcard character (or wildcard symbol) and stands for anystring ofcharacters. A common use of the wildcard is in searching for files on a computer. For instance, if a user wished to find a document calledDocument 1, search terms such asDoc* andD*ment* would return this file. Due to being a wildcard, they could also return files likeDocument 2 and (only the latter)Dark Knight Monument.jpg.Document* would in fact return any file that begins withDocument, andD*ment* any file that began with D and had 'ment' somewhere in its name.
In somegraphical user interfaces, an asterisk is pre- or affixed to the current working document name shown in a window's title bar to indicate that unsaved changes exist.
In many computing andInternet applications, an asterisk is displayed in place of the characters of sensitive or confidential visible information, such as a password.
InCommodore (and related)file systems, an asterisk appearing next to a filename in a directory listing denotes an improperly closed file, commonly called a "splat file".
InHTMLweb forms, a (usually red) asterisk can be used to denote required fields.
Chat room etiquette calls on one asterisk to correct a misspelled word or typo that has already been submitted. For example, one could postlck, then follow it with*luck orluck* (the placement of the * on the left or right is a matter of personal style) to correct the word's spelling, or if it's someone else that notices the mistake, they might also use*luck orluck*.[24] This also applies to typos that result in a different word from the intended one but are correctly spelled.
Incomics, enclosing a word or phrase between two asterisks is used to denote an action the subject is "performing", e.g.*cough*.[25][better source needed]
InMarkdown and other markup languages, surrounding a set of characters or words in one asterisk italicizes, two asterisks bolds, and three asterisks both italicizes and bolds.[26] See the table below for examples of all three uses of the asterisk in Markdown, including how it translates to HTML and how it renders.
Markdown
Italicized text is the*cat's meow*.
I just love**bold text**.
This text is ***really important***.
HTML
Italicized text is the<em>cat's meow</em>.
I just love<strong>bold text</strong>.
This text is<em><strong>really important</strong></em>.
Some models ofadding machines andprinting calculators use the asterisk to denote thetotal, or the terminal sum or difference of an addition or subtraction sequence, respectively. The symbol is sometimes given on the printout to indicate this total.[citation needed]
InPerl, the asterisk is used to refer to thetypeglob of all variables with a given name.
InRuby andPython, the asterisk has two specific uses. First, the unary * operator applied to a list object inside a function call will expand that list into the positional arguments of the function call. Second, a parameter preceded by *in the parameter list in a function definition will result in any extra positional parameters being aggregated into atuple (Python) orarray (Ruby), and likewise a parameter preceded by ** will result in any extrakeyword parameters being aggregated into adictionary (Python) orhash (Ruby):
fromtypingimportAnydeffunction1(a:int,b:int,c:int,d:int)->None:print(a,b,c,d)deffunction2(first:int,*args:tuple[int,...])->None:# args will be a tuple# the name 'args' is convention: it may be any parameter nameprint(args)deffunction3(first:int,**kwargs:dict[str,Any])->None:# kwargs will be a dict# the name 'kwargs' is convention: it may be any parameter nameprint(kwargs)function1(1,2,3,4)# prints 1 2 3 4function1(*[1,2,3,4])# prints 1 2 3 4function1(**{"a":5,"b":6,"c":7,"d":8})# prints 5 6 7 8function2(1,2,3,4)# prints (2, 3, 4), 1 is not part of argsfunction2(99)# prints (), unfilled *parameter will be ()function3(0,e=3,f=9)# prints {'e': 3, 'f': 9}, 0 is not part of kwargsfunction3(0)# prints {}, unfilled **parameter will be {}
In IBMJob Control Language, the asterisk has various functions, including in-stream data in the DD statement, the default print stream asSYSOUT=*, and as a self-reference in place of a procedure step name to refer to the same procedure step where it appears.
InHaskell, the asterisk represents the set of well-formed, fully applied types; that is, a 0-arykind of types.
In theB programming language and languages that borrow syntax from it, such asC,PHP,Java, orC#, comments in thesource code (for information to people, ignored by thecompiler) are marked by an asterisk combined with the slash:
/* This section displays message if user input was not valid (comment ignored by compiler) */
The asterisk was a supported symbol on the IBM 026Keypunch (introduced in 1949 and used to createpunch cards with data for early computer systems).[27] It was also included in theFIELDATA character encoding[28] and theASCII standard.[29][30][31]
Ineconomics, the use of an asterisk superscript indicates that thevariable such asprice,output, oremployment is at its optimal level (that which is achieved in a perfect market situation). For instance, is the price level when output is at its corresponding optimal level of.
Also in international economics asterisks are commonly used to denote economic variables in a foreign country. So, for example, is the price of the home good and is the price of the foreign good, etc.
In theA-Level examinations in theUnited Kingdom and thePSLE inSingapore, A* ("A-star") is a special top grade that is distinguished from grade A.
In theHong Kong Diploma of Secondary Education (HKDSE) examination inHong Kong, 5** (5-star-star) and 5* (5-star) are two special top grades that are distinguished from Level 5. Level 5** is the highest level a candidate can attain in HKDSE.
Certain categories of character types inrole-playing games are calledsplats, and the game supplements describing them are calledsplatbooks. This usage originated with the shorthand "*book" for this type of supplement to variousWorld of Darkness games, such asClanbook: Ventrue (forVampire: The Masquerade) orTribebook: Black Furies (forWerewolf: The Apocalypse), and this usage has spread to other games with similar character-type supplements. For example,Dungeons & Dragons Third Edition has had several lines of splatbooks: the "X & Y" series includingSword & Fist andTome & Blood prior to the "3.5" revision, the "Complete X" series includingComplete Warrior andComplete Divine, and the "Races of X" series includingRaces of Stone andRaces of the Wild.
InMagic: The Gathering, an asterisk is used on a creature's power and/or toughness when it's a variable amount.
In manyMUDs andMOOs, as well as "male", "female", and other more esoteric genders, there is a gender called "splat", which uses an asterisk to replace the letters that differ in standard English gender pronouns. For example,h* is used rather thanhim orher. Also, asterisks are used to signify doing an action, for example, "*action*".
Inlinguistics, an asterisk may be used for a range of purposes depending on what is being discussed. The symbol is used to indicate reconstructed words ofproto-languages (for which there are no records). For modern languages, it may be placed before posited problematic word forms, phrases or sentences to flag that they are hypothetical, ungrammatical, unpronounceable, etc.
Using the asterisk for descriptive and not just historical purposes arose in the 20th century.[35]: 334 By analogy with its use in historical linguistics, the asterisk was variously prepended to "hypothetical" or "unattested" elements in modern language.[35]: 332 Its usage also expanded to include "non-existent" or "impossible" forms.Leonard Bloomfield (1933) uses the asterisk with forms such as*cran, impossible to occur in isolation:cran- only occurs within the compoundcranberry.[36]: 160 [35]: 331 Such usage for a "non-existent form" was also found in French, German and Italian works in the middle of the 20th century.[35]: 332–34
Asterisk usage in linguistics later came to include not just impossible forms, but "ungrammatical sentences", those that are "ill formed for the native speaker".[35]: 332 The expansion of asterisk usage to entire sentences is often credited toNoam Chomsky, but Chomsky in 1968 already describes this usage as "conventional".[35]: 330 Linguist Fred Householder claims some credit,[37]: 365 [35]: 331 but Giorgio Graffi argues that using an asterisk for this purpose predates his works.[35]: 336 [a]
The meaning of the asterisk usage in specific linguistic works may go unelucidated so can be unclear.[37]: 369 [b] Linguistics sometimes uses double asterisks (**), another symbol such as thequestion mark, or both symbols (e.g.?*) to indicate degrees of unacceptability.[37]: 369
A double asterisk (**) sometimes indicates an intermediary or proximate reconstructed form (e.g. a single asterisk for reconstructedthirteenth century Chinese and a double asterisk for reconstructions of olderAncient Chinese[39]: 5 or a double asterisk for proto-Popolocan and a single asterisk for intermediary forms[40]: 322 ).
In other cases, the double asterisk denotes a form that would be expected according to a rule, but is not actually found. That is, it indicates a reconstructed form that is not found or used, and in place of whichanother form is found in actual usage:
For the plural, **kubar would be expected, but separate masculine pluralakābir أكابر and feminine pluralkubrayāt كبريات are found as irregular forms.
In most areas of linguistics, but especially insyntax, an asterisk in front of a word or phrase indicates that the word or phrase is not used because it isungrammatical.[35]: 332
wake her up / *wake up her
An asterisk before a parenthesis indicates that the lack of the word or phrase inside is ungrammatical, while an asterisk after the opening bracket of the parenthesis indicates that the existence of the word or phrase inside is ungrammatical—e.g., the following indicates "go the station" would be ungrammatical:
go *(to) the station
Use of an asterisk to denote forms or sentences that are ungrammatical is often complemented by the use of thequestion mark (?) to indicate a word, phrase or sentence that is avoided, questionable or strange, but not necessarily outright ungrammatical.[c]
Other sources go further and use several symbols (e.g. the asterisk, question mark, anddegree symbol°) to indicate gradations or a continuum of acceptability.[d]
Since a word marked with an asterisk could mean either "unattested" or "impossible", it is important in some contexts to distinguish these meanings. In general, authors retain asterisks for "unattested", and prefixx,**,†, or? for the latter meaning.[e] An alternative is to append the asterisk (or another symbol, possibly to differentiate between even more cases) at the end.[citation needed]
In phonetic transcription using theInternational Phonetic Alphabet and similar systems, an asterisk was historically used to denote that the word it preceded was a proper noun.[47][48] See this example from W. Perrett's 1921 transcription of Gottfried Keller'sDas Fähnlein der sieben Aufrechten:[49]
A notation to denote aparallel sum of two operands (most authors, however, instead use a or sign for this purpose).
The asterisk is used in all branches of mathematics to designate a correspondence between two quantities denoted by the same letter – one with the asterisk and one without.
In fine mathematical typography, theUnicode characterU+2217∗ASTERISK OPERATOR (in HTML, ∗; not to be confused withU+204E⁎LOW ASTERISK) is available. This character also appeared in the position of the regular asterisk in thePostScript symbol character set in theSymbol font included with Windows and Macintosh operating systems and with many printers.[citation needed] It should be used for a large asterisk that lines up with the other mathematical operators, sitting on the math centerline rather than on the text baseline.[52]
In the Geneva Bible and the King James Bible, an asterisk is used to indicate a marginal comment or scripture reference.
In theLeeser Bible, an asterisk is used to mark off the seven subdivisions of the weekly Torah portion. It is also used to mark the few verses to be repeated by the reader of the Haftara.
In American printings of theBook of Common Prayer, an asterisk is used to divide a verse of a Psalm in two portions for responsive reading. British printings use a spaced colon (" : ") for the same purpose.[53]
Inpointed psalms, an asterisk is used to denote a break or breath.
AStar of Life, a six-bar asterisk overlaid with theRod of Asclepius (the symbol of health), may be used as an alternative to cross or crescent symbols on ambulances.
In many scientific publications, the asterisk is employed as a shorthand to denote thestatistical significance of results when testinghypotheses. When the likelihood that a result occurred by chance alone is below a certain level, one or more asterisks are displayed. Popular significance levels are <0.05 (*), <0.01 (**), and <0.001 (***).
On atone dialling telephone keypad, the asterisk (calledstar) is one of the two special keys (the other is the'square key – almost invariably replaced by thenumber sign# (called 'pound sign' (US), 'hash' (other countries), or 'hex'), and is found to the left of the zero[54]). They are used to navigate menus in systems such asvoice mail, or invertical service codes. Itscodepoint inUnicode isU+2217∗ASTERISK OPERATOR (∗) as a valid alternative usage.[55]
The asterisk is used to call out afootnote, especially when there is only one on the page. Less commonly, multiple asterisks are used to denote different footnotes on a page (i.e., *, **, ***).[56][57] Typically, an asterisk is positioned after a word or phrase and preceding its accompanying footnote. Other characters are also used for this purpose, such asdagger (†, ‡) or superscript letters and numbers (as in Wikipedia). In marketing and advertising, asterisks or other symbols are used to refer readers discreetly to terms or conditions for a certain statement, the "small print".
In English-language typography the asterisk is placed after all other punctuation marks (for example, commas, colons, or periods) except for the dash.[58][59]
Asterisks may denote conversationalrepair, or corrections to misspelling or misstatements in previous electronic messages, particularly when replacement or retraction of a previous writing is not possible, such as with "immediate delivery" messages or "instant messages" that can not be edited. Usually this takes the form of a message consisting solely of the corrected text, with an asterisk placed before (or after) the correction. For example, one might send a message reading "*morning" or "morning*" to correct the misspelling in the message "I had a good mroning".[24][citation needed]
Bounding asterisks as "a kind of self-describing stage direction", as linguistBen Zimmer has put it. For example, in "Another gas station robbery *sigh*", the writer uses *sigh* to express disappointment (but does not necessarily literally sigh).[60]
Bounding asterisks can also represent an action in online situations where they aren't shown.[61]
It is formed by placing an asterisk after thestem and appending the feminine plural suffix "-innen". For example,Fahrer ([male] driver, singular & plural) becomesFahrer*innen (drivers). The gender star makes it possible to refer to allgenders while also includingnon-binary people.[63]
Alternatives to the gender star includeBinnen-I (with medial capitalI), thegender gap (where anunderscore takes the place of the asterisk) or using inherently gender neutral terms, such as 'people' instead of 'man' or 'woman'.[66]
TheUnicode standard has a variety of asterisk-like characters, compared in the table below. (Characters will display differently in different browsers and fonts.) The reason there are so many is chiefly because of the controversial[citation needed] decision to include in Unicode the entireZapf Dingbats symbol font.
^"...Chomsky adopted, with some delay, a convention which had been (possibly) circulated among generative grammarians by Householder. However, Householder (who was not a generative grammarian) was simply following a practice which had already been introduced by others, and which was so automatic as to be adopted almost unconsciously."[35]: 336
^The numerous and confusing uses are detailed in Householder (1973).[37]
^One article notes succinctly that"...common practice in linguistics [is that] an asterisk preceding a word, a clause or a sentence is used to indicate ungrammaticality or unacceptability, while a question mark is used to indicate questionable usage",[41]: 15 another that,"A question mark indicates that the example is marginal; an asterisk indicates unacceptability"[42]: 409 and another that"examples preceded by an asterisk are ungrammatical, and those preceded by a question mark would be considered strange".[43]: 623
^One example is"rough approximations of acceptability are given in four gradations and indicated as follows: normal and preferred, no mark; acceptable but not preferred, degree sign°; marginally acceptable, question mark (?); unacceptable, asterisk (*)."[44]: 123–24
^For example, one linguistic article states that,"A question mark (?) denotes uncertainty; an asterisk (*) indicates a classificatory base not encountered in my own data."[45]: 119
