An asterisk (*; Late Latin: asteriscus, from Greek: ἀστερίσκος, asteriskos, "little star")[1] is a typographical symbol or glyph. It is so called because it resembles a conventional image of a star. Computer scientists and mathematicians often pronounce it as star (as, for example, in the A* search algorithm or C*-algebra). In English, an asterisk is usually five-pointed in sans-serif typefaces, six-pointed in serif typefaces, and six- or eight-pointed when handwritten.
The asterisk is derived from the need of the printers of family trees in feudal times for a symbol to indicate date of birth. The original shape was seven-armed,[citation needed] each arm like a teardrop shooting from the center. Many cultures have their own unique versions of the asterisk.[citation needed]
In computer science, the asterisk is commonly used as a wildcard character, or to denote pointers, repetition, multiplication or to censor objectionable words or text.
Usage
Typography
The asterisk is used to call out a footnote, especially when there is only one on the page. Less commonly, multiple asterisks are used to denote different footnotes on a page. (i.e., *, **, ***) Typically, an asterisk is positioned after a word or phrase and preceding its accompanying footnote.
Three spaced asterisks centered on a page may represent a jump to a different scene or thought.
A group of three asterisks arranged in a triangular formation ⁂ is called an asterism.
One or more asterisks may be used to strike out portions of a word to avoid offending by using the full form of a profanity (f**k), to preserve anonymity (Peter J***), or to avoid profanation of a holy name, especially in Jewish usage (G*d).
Asterisks are sometimes used as an alternative to typographical bullets to indicate items of a list.
Asterisks can be used in textual media to represent *emphasis* when bold text is not available (e.g. email).
Linguistics
Historical linguistics
In historical linguistics, an asterisk immediately before a word indicates that the word is not directly attested, but has been reconstructed on the basis of other linguistic material (see also comparative method).
In the following example, the Proto-Germanic word ainlif is a reconstructed form.
*ainlif → endleofan → eleven
A double asterisk indicates a form that would be expected according to rule, but is not actually found:
For the plural, **kubar would be expected, but separate masculine plural akābir أكابر and feminine plural kubrayāt كبريات are found as irregular forms.
Generativist tradition in linguistics
In generativism, especially syntax, an asterisk in front of a word or phrase indicates that the word or phrase is ungrammatical.
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 a parenthesis indicates that the existence of the word or phrase inside is ungrammatical.
go *(to) the station
go (*to) home
Ambiguity
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 asterisk for "unattested", and prefix ˣ, **, or a superscript "?" for the latter meaning.
Music
In musical notation the sign Music-pedalup.svg indicates when the sustain pedal of the piano should be lifted.
In liturgical music, an asterisk is often used to denote a deliberate pause.
Computing
Computer science
In computer science, the asterisk is used in regular expressions to denote zero or more repetitions of a pattern; this use is also known as the Kleene star or Kleene closure after Stephen Kleene.
In the Unified Modeling Language, the asterisk is used to denote zero to many classes.
Computer interfaces
In some command line interfaces, such as the Unix shell and Microsoft's Command Prompt, the asterisk is the wildcard character and stands for any string of characters. This is also known as a wildcard symbol. A common use of the wildcard is in searching for files on a computer. For instance, if a user wished to find a document called Document 1, search terms such as Doc* and D*ment* would return this file. Document* would also return any file that begins with Document.
In some graphical user interfaces, in particular older Microsoft applications, an asterisk is prepended to the current working document name shown in a window's title bar to indicate that unsaved changes exist. The asterisk was also used as a mask to hide passwords being entered into a text box, until Windows XP where this was changed to a bullet.
In Commodore (and related) filesystems, an asterisk appearing next to a filename in a directory listing denotes an improperly closed file, commonly called a "splat file."
In travel industry Global Distribution Systems, the asterisk is the display command to retrieve all or part of a Passenger Name Record.
In HTML web forms, an asterisk can be used to denote required fields.
Chat Room etiquette calls on one asterisk to correct a misspelled word that has already been submitted. For example, one could post lck, then follow it with luck* or *luck.
Enclosing a phrase between two asterisks is used to denote an action the user is "performing", e.g. *pulls out a paper*, although this usage is also common on forums, and less so on most chat rooms due to /me or similar commands. Hyphens (-action-) and double colons (::action::) are also used for similar purposes.
