The typographic character @, the at sign, is the abbreviation for the phrase "at the rate of" in accounting and commercial invoices, e.g. “7 widgets @ $2 ea. = $14”. Nowadays, this commercial character is ubiquitous because it appears in all e-mail addresses. In English, it is informally spoken as at or the at sign or the at symbol. Formally, its official, typographic character nomenclature is commercial at in the ANSI/CCITT/Unicode character encoding standards. Some historical names are mentioned in the "History" section below.

[edit] History
These are some theories about the origin of the commercial at character in modern usage:
- Medieval monks abbreviated the Latin word ad (at, toward, by, about) next to a numeral.
- It was a 15th-century Spanish unit of weight: arroba = jar.
- The abbreviated Greek preposition ανά, ana, meaning at the rate of, its commercial usage.
- An Italian academic claims to have traced the @ symbol to the Italian Renaissance, in a Venetian mercantile document signed by Francesco Lapi on May 4, 1537.[1] The document is about commerce with Pizarro, in particular the price of an @ of wine in Peru; @ meant amphora (Italian anfora; Spanish and Portuguese arroba). Currently, the word arroba means the at-symbol and a unit of weight (cf. below). In this usage, the symbol represents one amphora, a unit of weight and volume based upon the capacity of the standard terracotta jar, and entered modern meaning and use as "at the rate of" in northern Europe.
- From Norman French "à" meaning "at" in the "each" sense, i.e. "2 widgets à £5.50 = £11.00" is the accountancy shorthand notation in English commercial vouchers and ledgers to the 1990s, when the e-mail usage superseded the accountancy usage. It also is so used in Modern French and Swedish; in this view, the at-symbol is a stylised form of à that avoids raising the writing hand from the page in drawing the symbol; this hybrid between @ and à in French handwriting is in street market signs.
- It could be the abbreviation of any word beginning in a.
The @ was present in the 1902 model Lambert typewriter made by Lambert Typewriter Company of New York. Its inclusion in the original 1963 ASCII character went unremarked as it was a standard commercial typewriter character, e.g. the 1961 IBM Selectric typewriter's keyboard included the @ (at-symbol).
[edit] Modern uses
In contemporary English usage, @ is a commercial symbol, meaning at and at the rate of. It has been used, rarely, in financial documents or grocers' price tags, and is not used in standard typography.[2]
Its most familiar contemporary use is in e-mail addresses (transmitted by SMTP), as in jdoe@example.com (the user jdoe working at the computer named example in the domain com). Ray Tomlinson is credited with introducing this usage in 1972. This idea of the symbol representing located at in the form "user@host" also is seen in other tools and protocols: the command ssh jdoe@www.example.com tries to establish a ssh connection to the computer with the hostname www.example.com using the username jdoe.
The @ is used in various programming languages though there is not a consistent theme to its usage. For example, in Perl, @ prefixes variables which contain arrays; in PHP, it is used just before a function to make the interpreter suppress errors that would be generated when using that function; in C#, @ is the literal string operator meaning that the string should be used "as is" and not be processed for escape sequences; in Java, it is used to denote annotations (sometimes called metadata) since version 5.0; in Ruby, @ prefixes instance variables, and @@ prefixes class variables.
In architecture, @ is used as a symbol meaning "every". For example, the phrase 2x4 @ 16" O.C. would denote placement of a 2x4 every 16" on center.
In modal logic, specifically when representing possible worlds, @ is sometimes used as a logical symbol to denote the actual world (the world we are 'at').
The @ is used as an alternative political spelling for typing in some Romance languages as a gender-neutral substitute for the masculine "o" in mixed sex groups and in cases where the sex is unknown. For example, the Portuguese/Spanish word "amigos" (friends), which can mean men and women friends or all men friends would be replaced with "amig@s". The character is intended to resemble a digraph of both the masculine letter "o" and the feminine letter "a". The usefulness of this is debatable; in Portuguese/Spanish, the masculine grammatical gender may include both men and women, while the feminine gender is exclusively for and about women; there is no neuter gender for most nouns. Some advocates of gender-neutral language-modification feel that using the male grammatical gender as a generic gender designator indicates implicit linguistic disregard for women. Many Portuguese/Spanish speakers think that this usage of the @ (at-sign) degrades Portuguese/Spanish; some argue it is just more cultural imperialism; generally, this construction is used only in personal, informal writing, and has no established pronunciation. Alternative forms would be amigos/as and amigⒶs using the circle-A of anarchism as the bisexual digraph.
In most roguelike games (Angband and NetHack), @ denotes the player character. Some roguelikes also use @ to denote any human being. This usage is because the @ resembles an overhead view of a person's head and shoulders.
The @ is also used sometimes (e.g. articles about missing persons, obituaries, brief reports) to denote an alias after a person's proper name, for instance: "John Smith @ Jean Smyth".
The @ may sometimes be used to represent a schwa, as the actual schwa character "ə" may be difficult to produce in many computers. It is used in this capacity in the ASCII IPA or Kirshenbaum IPA scheme.
In online discourse, the @ is used by some anarchists as a substitute for the traditional circle-A .
It is frequently used in Leet as a substitute for the letter A.
In Malagasy, @ is an informal abbreviation for amin'ny.
[edit] "Commercial at" in other languages
In most languages other than English, @ was less common before e-mail became widespread in the mid-1990s, although most typewriters included the symbol. Consequently, it is often perceived in those languages as denoting "The Internet", computerization, or modernization in general.
- In Basque it is called a bildua ("rounded a")
