The history of the @ symbol is a journey from medieval shorthand to mercantile trade and, finally, to its role as the linchpin of digital communication. While it feels modern, its roots are centuries old.
Early Origins and Theories
The precise beginning of the symbol is shrouded in mystery, but several compelling theories exist:
- Medieval Shorthand: Linguists trace it to medieval monks who may have created it as a shortcut for the Latin preposition ad (meaning “to,” “at,” or “toward”). By wrapping the “d” around the “a,” they saved time and parchment.
- Religious Text: The oldest known instance is found in a 1345 Bulgarian translation of the Manasses Chronicle, where it was used to replace the letter “A” in the word “Amen”.
- French Influence: Another theory suggests it evolved from a stylized version of the French à  (“at”). YouTube +4
The “Commercial At”
By the 16th century, the symbol became a standard tool for merchants:
- The Amphora: In 1536, Florentine merchant Francesco Lapi used @ in a letter to represent an amphora, a unit of volume for wine and grain.
- The Arroba: In Spain and Portugal, it became shorthand for the arroba, a unit of weight (roughly 25 pounds) derived from the Arabic ar-rub (“a quarter”).
- Accounting Standard: In the English-speaking world, it settled into commerce as shorthand for “at the rate of” (e.g., “10 widgets @ $1 each”)Wikipedia +5
The Digital Revolution
Despite its commercial use, the @ symbol was nearly lost to history because it was not included on the first mechanical typewriters in the mid-1800s. Smithsonian Magazine +1
- Ray Tomlinson and Email: In 1971, computer scientist Ray Tomlinson was looking for a symbol to separate a user’s name from their host computer. He chose @ because it was an existing key on his Model 33 teletype that was rarely used in programming, ensuring no confusion.
- Social Media: The symbol’s fame exploded further in 2006–2007 when Twitter (now X) adopted it for user handles and mentions.
- Museum Recognition: In 2010, the Museum of Modern Art (MoMA) in New York added the symbol to its permanent collection as a design icon.Encyclopedia Britannica +4
International Nicknames
While English speakers simply call it “the at sign,” other cultures have more creative names.
- Animals: “Snail” (chiocciola in Italian), “Monkey’s tail” (apestaart in Dutch), or “Elephant’s trunk” (snabel-a in Swedish).
- Food: “Strudel” in Hebrew or “Cinnamon roll” in other contexts.
- Abstract: “Worm” (kukac in Hungarian) or “Small duck” (papaki in Greek).Â
