The at sign, @ , is normally read aloud every bit "at"; it is also usually called the at symbol, commercial at, or address sign. It is used as an accounting and invoice abbreviation meaning "at a rate of" (eastward.g. 7 widgets @ £two per widget = £xiv),[one] merely information technology is now seen more widely in email addresses and social media platform handles.

The absence of a unmarried English discussion for the symbol has prompted some writers to use the French arobase [2] or Spanish and Portuguese arroba, or to coin new words such equally ampersat [3] and asperand,[4] or the (visual) onomatopoeia strudel,[v] but none of these have achieved broad use.

Although not included on the keyboard of the earliest commercially successful typewriters, it was on at least one 1889 model[half dozen] and the very successful Underwood models from the "Underwood No. 5" in 1900 onward. It started to exist used in email addresses in the 1970s, and is now routinely included on almost types of computer keyboards.

History [edit]

@ symbol used as the initial "a" for the "amin" (amen) formula in the Bulgarian of the Manasses Relate, c. 1345.[7]

@ used to signify French " à " ("at") from a 1674 protocol from a Swedish court ( Arboga rådhusrätt och magistrat )

The earliest nevertheless discovered symbol in this shape is institute in a Bulgarian translation of a Greek chronicle written by Constantinos Manasses in 1345. Held today in the Vatican Apostolic Library, it features the @ symbol in identify of the capital alphabetic character alpha "Α" as an initial in the give-and-take Amen; however, the reason behind it being used in this context is withal unknown. The evolution of the symbol as used today is not recorded.

It has long been used in Catalan, Spanish and Portuguese as an abbreviation of arroba, a unit of weight equivalent to 25 pounds, and derived from the Arabic expression of "the quarter" ( الربع pronounced ar-rubʿ).[nine] A symbol resembling an @ is institute in the Castilian "Taula de Ariza", a registry to denote a wheat shipment from Castile to Aragon, in 1448.[10] An Italian academic, Giorgio Stabile, claims to have traced the @ symbol to the 16th century, in a mercantile document sent past Florentine Francesco Lapi from Seville to Rome on May 4, 1536.[10] The document is about commerce with Pizarro, in particular the price of an @ of wine in Peru. Currently, the word arroba ways both the at-symbol and a unit of weight. In Venetian, the symbol was interpreted to hateful amphora ( anfora ), a unit of weight and volume based upon the capacity of the standard amphora jar since the 6th century.

Modern utilise [edit]

Commercial usage [edit]

In contemporary English usage, @ is a commercial symbol, meaning at and at the rate of or at the price of. It has rarely been used in fiscal ledgers, and is non used in standard typography.[xi]

Trademark [edit]

In 2012, "@" was registered as a trademark with the German language Patent and Merchandise Marking Function.[12] A cancellation request was filed in 2013, and the counterfoil was ultimately confirmed past the High german Federal Patent Court in 2017.[13]

Email addresses [edit]

A mutual contemporary use of @ is in email addresses (using the SMTP system), equally in jdoe@example.com (the user jdoe located at the domain example.com). Ray Tomlinson of BBN Technologies is credited for having introduced this usage in 1971.[4] [14] This thought of the symbol representing located at in the form user@host is as well seen in other tools and protocols; for example, the Unix beat command ssh jdoe@example.net tries to constitute an ssh connection to the computer with the hostname example.net using the username jdoe.

On web pages, organizations often obscure the electronic mail addresses of their members or employees by omitting the @. This practice, known equally address munging, makes the email addresses less vulnerable to spam programs that scan the internet for them.

[edit]

On some social media platforms and forums, usernames may be prefixed with an @ (in the form @johndoe); this type of username is often referred to as a "handle"[ citation needed ].

On online forums without threaded discussions, @ is commonly used to announce a reply; for example: @Jane to respond to a comment Jane made before. Similarly, in some cases, @ is used for "attention" in email messages originally sent to someone else. For example, if an email was sent from Catherine to Steve, simply in the body of the email, Catherine wants to brand Keirsten enlightened of something, Catherine will start the line @Keirsten to indicate to Keirsten that the following sentence concerns her.[ citation needed ] This also helps with mobile email users who might not come across bold or colour in electronic mail.

In microblogging (such as on Twitter and GNU social-based microblogs), an @ earlier the user name is used to send publicly readable replies (due east.thou. @otheruser: Message text here). The blog and client software tin can automatically interpret these every bit links to the user in question. When included as part of a person's or visitor'southward contact details, an @ symbol followed by a name is commonly understood to refer to a Twitter handle. A similar use of the @ symbol was also made available to Facebook users on September fifteen, 2009.[xv] In Net Relay Conversation (IRC), it is shown before users' nicknames to denote they have operator condition on a channel.

Sports usage [edit]

In American English the @ can be used to add information near a sporting event. Where opposing sports teams have their names separated by a "v" (for versus), the away team tin can be written get-go – and the normal "v" replaced with @ to convey at which squad's home field the game volition exist played.[16] This usage is non followed in British English language, since conventionally the abode team is written start.

  • In CSS, @ is used in special statements exterior of a CSS cake.[19]
  • In C#, it denotes "verbatim strings", where no characters are escaped and 2 double-quote characters represent a single double-quote.[20] As a prefix it also allows keywords to be used as identifiers,[21] a form of stropping.
  • In D, it denotes role attributes: like: @safe, @nogc, user defined @('from_user') which tin be evaluated at compile time (with __traits) or @property to declare properties, which are functions that can be syntactically treated every bit if they were fields or variables.[22]
  • In DIGITAL Control Language, the @ graphic symbol was the command used to execute a command procedure. To run the command procedure VMSINSTAL.COM, one would type @VMSINSTAL at the command prompt.
  • In Along, it is used to fetch values from the address on the top of the stack. The operator is pronounced as "fetch".
  • In Haskell, it is used in so-called every bit-patterns. This notation tin can be used to requite aliases to patterns, making them more readable.
  • in HTML, information technology can exist encoded as @ [23]
  • In J, denotes function limerick.
  • In Java, it has been used to denote annotations, a kind of metadata, since version 5.0.[24]
  • In LiveCode, it is prefixed to a parameter to indicate that the parameter is passed by reference.
  • In an LXDE autostart file (as used, for case, on the Raspberry Pi calculator), @ is prefixed to a command to indicate that the command should be automatically re-executed if it crashes.[25]
  • In ML, it denotes listing concatenation.
  • In modal logic, specifically when representing possible worlds, @ is sometimes used every bit a logical symbol to denote the bodily world (the world we are "at").

  • In Pascal, @ is the "address of" operator (it tells the location at which a variable is found).
  • In Perl, @ prefixes variables which contain arrays @array, including array slices @assortment[two..five,7,ix] and hash slices @hash { 'foo' , 'bar' , 'baz' } or @hash { qw(foo bar baz) } . This use is known as a sigil.
  • In PHP, it is used just before an expression to make the interpreter suppress errors that would be generated from that expression.[26]
  • In Python 2.four and up, it is used to decorate a function (wrap the function in some other one at creation time). In Python 3.v and up, it is also used as an overloadable matrix multiplication operator.[27]
  • In Razor, information technology is used for C# code blocks.[28]
  • In Ruby, it functions every bit a sigil: @ prefixes instance variables, and @@ prefixes class variables.[29]
  • In Scala, it is used to denote annotations (as in Java), and too to bind names to subpatterns in pattern-matching expressions.[thirty]
  • In Swift, @ prefixes "annotations" that can be applied to classes or members. Annotations tell the compiler to apply special semantics to the declaration like keywords, without calculation keywords to the language.
  • In T-SQL, @ prefixes variables and @@ prefixes "niladic" system functions.
  • In several xBase-type programming languages, like DBASE, FoxPro/Visual FoxPro and Clipper, it is used to denote position on the screen. For case: @1,1 SAY "HELLO" to show the discussion "HELLO" in line ane, column one.
    • In FoxPro/Visual FoxPro, information technology is likewise used to indicate explicit pass past reference of variables when calling procedures or functions (merely it is not an address operator).[31]
  • In a Windows Batch file, an @ at the start of a line suppresses the echoing of that command. In other words, is the same as Repeat OFF applied to the current line merely. Normally a Windows command is executed and takes outcome from the next line onward, but @ is a rare example of a command that takes outcome immediately. Information technology is virtually normally used in the form @echo off which not only switches off echoing simply prevents the command line itself from being echoed.[32] [33]
  • In Windows PowerShell, @ is used as array operator for array and hash table literals and for enclosing here-string literals.[34]
  • In the Domain Name System (DNS), @ is used to represent the $ORIGIN, typically the "root" of the domain without a prefixed sub-domain. (Ex: wikipedia.org vs. world wide web.wikipedia.org)
  • In associates language, @ is sometimes used as a dereference operator.[35]

Gender neutrality in Spanish [edit]

In Spanish, where many words end in "-o" when in the masculine gender and terminate "-a" in the feminine, @ is sometimes used as a gender-neutral substitute for the default "o" catastrophe.[36] For example, the discussion amigos traditionally represents non only male friends, but also a mixed group, or where the genders are not known. The proponents of gender-inclusive language would supplant it with amig@s in these latter ii cases, and use amigos merely when the group referred to is all-male and amigas only when the group is all female. The Real Academia Española disapproves of this usage.[37]
