Ever looked at your keyboard and wondered why that weird little "a with a circle" is even there? It’s ubiquitous. We use it for emails, Instagram handles, and tagging friends in memes. Most of us just call it the at symbol. It’s funny because, for something we touch dozens of times a day, its history is a mess of merchant ledgers, Italian wine jugs, and a very stressed-out computer engineer in the seventies.
People get it wrong constantly. They think Ray Tomlinson "invented" the symbol in 1971. He didn't. He just rescued it from obscurity. Before it lived on the internet, the at symbol was a dusty tool for accountants. If you were buying five barrels of salted fish at 10 pence per barrel, you’d write "5 barrels @ 10p." It was shorthand for "at the price of."
Where did the @ come from?
The origin stories are kinda wild. Some paleographers—people who study old handwriting—trace it back to the 6th or 7th century. Monks were tired. Copying manuscripts by hand is brutal work. They supposedly started merging the Latin word "ad" (meaning toward or at) into a single character to save time. The 'd' wrapped around the 'a' like a protective hug.
But then you have the Italian researchers. In 2000, Giorgio Stabile, a professor at La Sapienza, found a 1536 letter written by a Florentine merchant named Francesco Lapi. Lapi used the at symbol to represent an "amphora." An amphora was a standard clay jar used for shipping wine or olive oil. It was a unit of measurement. It’s wild to think that the thing you use to tweet at a celebrity used to represent a jug of fermented grapes in the Mediterranean.
It appeared in Spanish and Portuguese records too as the "arroba." This was a weight equivalent to about 25 pounds. Even today, if you go to a market in parts of Spain, you might see the at symbol on a sign for produce. It’s not a digital handle there; it’s just how much the pork weighs.
The 1971 Pivot: Why your email looks the way it does
Technology almost killed the at symbol. When early typewriters were being built, the @ was often left off the keyboard because it wasn't used enough in general writing. It was too "niche" for the average person. It only survived because it was useful for business invoices.
Then came Ray Tomlinson.
He was working on ARPANET, the prehistoric version of our internet. He needed a way to send a message from one computer to another, but he had a problem: how do you tell the computer which part of the address is the user and which part is the host? He needed a character that no one used in their names. He looked at his Model 33 Teletype keyboard.
There it was. The at symbol.
It was perfect. It literally meant "at." So, "tomlinson @ bbn-tenexa" made logical sense. It told the machine that the user was at a specific location. Ray chose it almost on a whim. He had no idea he was creating a global icon. If he’d picked the percent sign or the ampersand, our digital lives would look fundamentally different today.
The global identity of the "A with a circle"
What’s truly fascinating is that while English speakers just say "at," the rest of the world got creative. They saw a shape and ran with it. Honestly, some of the names are better than ours.
In Taiwan, it’s "little mouse." In Greece, it’s "little duckling." The Dutch call it apenstaartje, which means "monkey's tail." The Germans often go with Klammeraffe, or "spider monkey." It seems like every culture looked at that swirling line and saw an animal. Except for the Italians, who stuck with chiocciola—the snail.
Think about that for a second. In a world that is increasingly homogenized by big tech, this one character still carries these weird, localized nicknames. It’s a rare piece of digital soul.

Misconceptions and the "Hidden" Meanings
You’ll sometimes see conspiracy theorists or "hidden history" buffs claim the at symbol is a secret Masonic mark or an ancient religious icon. There is zero evidence for that. It’s a commercial shorthand. It’s boringly practical.
Another mistake? Thinking the symbol is a "character" in the same way 'A' or 'B' is. In the early days of computing, different systems interpreted it differently. On some old systems, typing the at symbol would actually delete the entire line you just wrote. It was a "kill" character. Imagine trying to send an email today and having your whole draft vanish because you typed your own address.
The Legal Status of a Symbol
Can you own the at symbol? Not really. But it has entered the world of high art. In 2010, the Museum of Modern Art (MoMA) in New York "acquired" the symbol for its architecture and design collection. They didn't buy it—you can't buy a symbol—but they recognized it as a masterpiece of design.
They argued that Tomlinson's use of the symbol was an act of "design" because he repurposed an existing tool for a completely new, revolutionary function. It’s the ultimate "ready-made." It costs nothing to use, it’s understood by everyone, and it has no single owner.

Why we can't quit the @
We’ve tried to replace it. Some early social networks tried using different delimiters. But the at symbol won. It won because it’s a preposition. It’s a bridge. It connects a person to a place or a person to a conversation.
It’s also surprisingly durable. In the era of touchscreens, the swirling motion of writing an @ is one of the few things that feels "fluid" compared to the blocky letters of the rest of the alphabet. It’s basically a doodle that became a legal requirement for digital existence.
Modern Uses You Might Not Know
- Programming: In languages like Python, it’s used for "decorators." In CSS, it’s for "at-rules" like @media.
- Accounting: It’s still used in its original form for unit pricing in some specialized software.
- Social Signifiers: Putting the symbol in a bio isn't just for handles anymore; it’s become a way to show affiliation or location.
Actionable Takeaways for the Digital Age
If you're dealing with the at symbol daily—which, let's face it, you are—there are a few practical things to keep in mind regarding security and formatting.
Protecting your email from scrapers.
Spambots crawl the web looking for the at symbol to harvest email addresses. If you have to put your email on a public website, write it as "name [at] domain [dot] com." It’s a low-tech fix, but it actually works because most basic scrapers are looking for that specific circular "a."
Handle consistency.
When you're picking a handle for social media, the at symbol is the prefix that defines your brand. Check availability across platforms using tools like Namechk before you commit. You want @YourName to be the same on X, Instagram, and TikTok.
Proper formatting in professional docs.
In formal writing, avoid using the symbol as a substitute for the word "at." It looks lazy. Keep the symbol for email addresses and handles. If you’re writing "I'll see you at the office," use the words. Using the symbol makes your professional correspondence look like a grocery receipt from 1950.
The at symbol is a survivor. It outlived the monks who likely invented it, the merchants who used it for wine, and it will probably outlive the very social media platforms that rely on it today. It is the ultimate example of how humans take old, discarded things and turn them into something indispensable.
