The @ sign, also known as the at symbol, commercial at, or address sign, is typically read aloud as “at.” It is most commonly found in email addresses and social media platform handles as an accounting and invoicing abbreviation meaning “at a rate of” (e.g., seven widgets @ £2 per widget = £14).

Because there is no single English name for the sign, some authors have substituted the French arobase or the Spanish and Portuguese arroba or coined new terms like ampersat, asperand, and strudel, but none of these have gained widespread acceptance.

It was on at least one 1889 model and the extremely popular Underwood models from the “Underwood No. 5” in 1900 forward, despite not being on the keyboard of the first commercially successful typewriters. It first appeared in email addresses in the 1970s and is currently found on all computer keyboards.

In a Bulgarian translation of a Greek chronicle published by Constantinos Manasses in 1345, the first sign in this shape has been identified. The @ sign replaces the capital letter alpha “A” in the word Amen, and it is kept at the Vatican Apostolic Library today. It’s unclear why it was utilized in this situation. There is no trace of the symbol’s development into what it is now.


Whatever the origin of the @ sign, it has a long history of use in Catalan, Spanish, and Portuguese as an abbreviation of arroba, a unit of weight corresponding to 25 pounds that is derived from the Arabic phrase “the quarter” (pronounced ar-rub). Giorgio Stabile, an Italian scholar, claims to have discovered the @ sign in a business document sent from Seville to Rome on May 4, 1536, by Florentine Francesco Lapi. The paper is about Pizarro’s business dealings, specifically the price of a bottle of wine in Peru. The name arroba now refers to both the at-symbol and a unit of weight. Since the 6th century, the sign has been understood as amphora (amphora), a unit of weight and volume based on the capacity of the ordinary amphora jar.

Even though the oldest fully developed modern @ sign is the one found on the above-mentioned Florentine letter, the first historical document containing a symbol resembling a @ as a commercial symbol is the Spanish “Taula de Ariza,” a registry to denote a wheat shipment from Castile to Aragon in 1448.

In email addresses (using the SMTP system), the @ symbol is commonly used, as in (the user jdoe located at the domain BBN Technologies’ Ray Tomlinson is credited with introducing this use in 1971. The Unix shell command ssh tries to create an ssh connection to the computer with the hostname using the username jdoe.
