What does @ mean in email? The story behind the symbol
what does the @ symbol stand for in an email address? This ubiquitous symbol has a surprising origin story that goes beyond its digital function. Discover how a simple keyboard choice by Ray Tomlinson shaped modern communication and learn about its centuries-old use in commerce and measurement.
What Does the @ Symbol Actually Mean in an Email Address?
The @ symbol in an email address is a straightforward piece of punctuation with a simple job. It stands for at and acts as a separator, indicating that a specific user (the username) is located at a particular domain. In the address [email protected], it tells the internets mail servers that the user jane.doe can be found at the domain example.com.
Its the digital equivalent of putting both a name and a full address on a piece of mail. Without it, there would be no clear way to distinguish the recipients name from the name of their mail server, making the entire system impossible to scale. It’s a small symbol with a massive responsibility.
The Accidental Inventor: Why Ray Tomlinson Chose the @ Symbol in 1971
The story of the @ symbol in email begins with Ray Tomlinson, a programmer working on ARPANET, the government network that would eventually evolve into the internet. Back in 1971, he was working on a program called SNDMSG that could send messages, but only to other users on the same computer. He wanted to send a message to someone on a different machine. To do this, he needed a way to separate the users name from the name of their host computer.
Looking down at his Model 33 Teletype keyboard, Tomlinson scanned for a character that wasnt likely to appear in a persons name or a computers hostname. He later explained his reasoning simply: I was mostly looking for a symbol that wasnt used much. And there werent a lot of options—an exclamation point or a comma. I could have used an equal sign, but that wouldnt have made much sense. (citation:3) He also noted that it was the only preposition on the keyboard, perfectly suiting its new purpose of describing a user at a location. (citation:5)
Tomlinson has admitted the choice was somewhat mundane. The reason its the @ sign is kind of boring, he said in an interview. Its the only preposition on the keyboard and it was a symbol that wasnt used very much. (citation:1)(citation:8) This practical, almost arbitrary decision created one of the most enduring symbols of the digital age.
The First Email and a Legacy Forged
After integrating the @ symbol into his program, Tomlinson sent the first network email between two machines sitting side-by-side in his lab in Cambridge, Massachusetts. The content of that historic message? He had no idea. In a 2009 interview, he confessed, The test messages were entirely forgettable, and I have, therefore, forgotten them. (citation:3) It was likely a random string of characters like QWERTYUIOP or something equally mundane.
Despite the lack of fanfare surrounding the first message, the impact was monumental. Tomlinson later reflected, Im often asked Did I know what I was doing? The answer is: Yeah I knew exactly what I was doing. I just had no notion whatsoever about what the ultimate impact would be. (citation:3) His simple invention has become so ingrained in modern life that in 2010, the Museum of Modern Art (MoMA) added the @ symbol to its architecture and design collection, acknowledging its transformative role in communication. (citation:2)(citation:3)
What Do You Call It? A World of Nicknames for @
While in English we call it the at sign, its unique shape has inspired a delightful array of nicknames in other languages, often based on animals or food. This section compares some of the most creative names for the @ symbol from around the world.
International Names for the @ Symbol
The table below highlights just a few of the many creative names for the @ symbol across different cultures:
Denmark/Sweden: Snabel-a (Elephants trunk A) (citation:4)(citation:9) Italy: Chiocciola (Snail) (citation:4)(citation:9) Greece: Παπάκι (Papaki) (Little duck) (citation:4)(citation:6)(citation:9) Germany: Klammeraffe (Spider monkey) (citation:9) China: Xiǎo lǎoshǔ (小老鼠) (Little mouse) (citation:2)(citation:6) Korea: Golbaeng-i (골뱅이) (Whelk, a type of sea snail) (citation:6) Hebrew: Shtrudel (שטרודל) (Strudel) (citation:4)(citation:9) Hungary: Kukac (Worm) (citation:4) Poland: Małpa (Monkey) (citation:6) Taiwan: Xiǎo lǎoshǔ (小老鼠) (Little mouse) (citation:8)
Beyond Email: The Ubiquity of @ in Modern Life
The symbols usefulness didnt stop with email. Its function as a marker or identifier has translated perfectly to other platforms. On social media, using @ to mention or reply to another user has become a universal standard. Twitter (now X), Instagram, and countless other platforms adopted it for this purpose. (citation:2)(citation:7) Youll even find it in programming languages, where it often denotes specific functions or properties. (citation:2)
Its role as a separator has historical roots in commerce, long before computers. In accounting, @ has been used for centuries to mean at a rate of, such as in the phrase 5 items @ $1.00 = $5.00. (citation:1)(citation:6) In Spanish and Portuguese, the symbol was even used as a unit of weight called the arroba, equal to about 25 pounds. (citation:3)(citation:2)(citation:6) So, while Ray Tomlinson gave the @ symbol its digital life, its history as a functional mark is far older than the internet itself.
Comparing Creative International Names for the @ Symbol
While its function is universal, the name for the @ symbol varies wildly across the globe. Here’s a look at how different cultures have nicknamed this ubiquitous symbol.
Scandinavia
Elephant's Trunk A
Snabel-a (Sweden/Denmark)
The loop of the @ resembles an elephant's trunk curling around the letter 'a'.
Southern Europe
Snail
Chiocciola (Italy), Caragol (Catalonia)
The spiral shape of the @ is reminiscent of a snail's shell.
East Asia
Little Mouse / Whelk (Sea Snail)
Xiao laoshu (China), Golbaeng-i (Korea)
Both names liken the symbol to small, curled creatures—a mouse's tail or a sea snail's shell.
Germanic & Slavic
Spider Monkey / Monkey
Klammeraffe (Germany), Małpa (Poland)
The symbol is seen as a monkey hanging by its curled tail.
These nicknames show a universal human tendency to relate abstract symbols to familiar objects. Animal names, particularly those with curled tails or shells, are a common theme across continents, proving that even in the digital age, our language is rooted in the natural world.How an Entrepreneur Finally Understood Her Email
Mai, who runs a small online shop in Ho Chi Minh City, had been using email for years but always felt a bit confused. She knew her address was '[email protected],' but she didn't understand what the 'at' part actually meant. It was just a symbol she typed without thinking.
One day, while setting up a new email account for her business on her laptop, she paused. 'Why is this symbol here?' she asked herself. She tried using other symbols, like a dash or a comma, but they didn't work. Frustrated, she nearly gave up, thinking she was doing something wrong.
Her teenage son came over and explained it simply. 'Think of it like our physical shop, Mom. 'thotrangmai' is the name of our store, and 'emailprovider.vn' is the name of the street and city where the post office finds it. The @ symbol is the glue that says the store is at that location.'
It finally clicked. Mai now understands her email address as a complete address, not a random string of characters. She even uses the analogy with her own customers, helping them understand how to reach her online. The simple explanation turned a confusing symbol into a powerful tool for her business.
Strategy Summary
It's a digital preposition.The '@' symbol fundamentally means 'at,' connecting a username to its specific domain location, just like an address on a letter.
One man's mundane choice changed the world.Ray Tomlinson selected the @ in 1971 simply because it was a rarely-used preposition on his keyboard, an almost arbitrary decision that created the standard for digital communication.
From 'snail' in Italian to 'little mouse' in Chinese, the symbol's unique shape has inspired a global collection of imaginative nicknames, often reflecting local fauna and cuisine.
Its function has ancient roots.Long before email, the @ symbol was a workhorse in accounting and commerce, representing 'at the rate of,' and even served as a unit of weight in Spanish and Portuguese.
Same Topic
Is '@' officially called the 'at sign'?
Yes, in English, the official and most common name is the 'at sign' or 'commercial at'. It's the standard term used in dictionaries, technical manuals, and style guides. However, its history as a commercial symbol meaning 'at the rate of' predates its email usage by centuries.
What did people use before the @ symbol in email addresses?
Before the @ became the universal standard, other symbols were used in different network systems. For example, on the older BITNET, addresses sometimes used a percent sign (%) or required users to spell out the word 'at'. The exclamation point was also used in a system called UUCP to specify the path an email should take between computers.
Could the first email ever be recovered?
Unfortunately, no. The first test emails Ray Tomlinson sent in 1971 were between two ARPANET computers that were not designed for long-term data storage. The messages were ephemeral and were likely lost as soon as the computers were turned off or rebooted. Tomlinson himself said the messages were forgettable and long gone.
Why does the @ symbol look like a snail to so many cultures?
The visual similarity is striking. The classic typographic form of the @ symbol—a circular or oval shape with a short, curly tail—closely resembles the shell and body of a snail or a similar curled creature. This shared visual perception likely explains why so many unrelated languages independently arrived at similar animal-based nicknames.
