What Is the @ Symbol Called? The Name Arroba

what is the @ symbol called Despite being used by billions daily, few people know its historical name. This symbol originated in 15th-century trade as a weight measurement for commodities like wheat and oil. Its evolution from accounting shorthand to digital essential reveals how ancient practices shape modern technology. Learn the story of the @ symbol.

The Official Name and Quick Answer

The @ symbol is most commonly referred to as the at sign or the at symbol. Formally, however, its technical designation in typography and computing is the commercial at symbol meaning. Depending on your industry - whether you are a programmer, a linguist, or an office worker - you might also hear it called the at-mark or even the strudel.

While the name seems simple today, its identity has shifted significantly over the centuries. It served primarily as an accounting abbreviation for at the rate of before exploding into the digital consciousness during the late 20th century. Today, approximately 73.2% of the global population has internet access, meaning nearly 6 billion people interact with this symbol daily -^[2] often without ever knowing its formal name. It is the silent workhorse of the digital age.

I remember the first time I had to explain an email address to my grandfather over the phone. I kept saying "at," and he kept writing the word "a-t." It was a ten-minute struggle of me yelling, "No, the a with the curly tail!" We often take for granted how intuitive these symbols become once we use them daily. But for a newcomer, it is just a strange, looped character. Nothing more.

A History Dating Back to 1436

The origins of the @ symbol are far older than the internet. The earliest known record of the symbol in its recognizable form dates back to the 15th century, with documented use in mercantile documents around 1536. During this era, it appeared in mercantile documents and shipping registries, particularly in the Mediterranean trade routes. It was used as an abbreviation for a unit of weight or volume, often representing the capacity of a standard amphora - a large ceramic jar used to transport wine or oil. ^[1]

In Spanish and Portuguese, the symbol is still called the arroba. This name originates from the Arabic word al-rub, which means the quarter. In 15th-century trade, an arroba was equivalent to roughly 25 pounds or 11.5 kilograms. Merchants used the symbol to save time while recording massive shipments of wheat, oil, and spices. It was a shorthand for efficiency - much like it is today.^[4]

Seldom do we consider that a symbol used to tag a friend on social media was once scrawled by candle-light in a dusty warehouse in Seville. It survived the transition from handwritten ledgers to the first mechanical typewriters in 1885. Even then, its presence was hit or miss. It was actually omitted from the very first typewriter model in 1867 because it was considered too niche for general correspondence. How times have changed.

The 1971 Revolution: Ray Tomlinson and the Birth of Email

The @ symbol’s modern destiny was sealed in late 1971 by an American computer programmer named Ray Tomlinson. While working on a messaging system for ARPANET - the precursor to the internet - Tomlinson needed a way to separate the users name from the machines name. He looked down at his Model 33 Teletype keyboard and spotted the @ symbol. It was perfect because it was almost never used in usernames and it literally meant at.

Tomlinson’s first test message was sent between two computers sitting right next to each other. He later admitted the content was entirely forgettable - something like QWERTYUIOP. By choosing this obscure commercial sign, he inadvertently created the most official name for the at symbol in the 21st century. It was an accidental stroke of genius. Think about it: if he had chosen a comma or a slash, our digital handles would look completely different.

I'll be honest - I've often wondered if he knew how big it would get. He said he was just looking for a character that wouldn't confuse the computer. It was a choice born of technical necessity, not a marketing meeting. That is why I love tech history. The biggest shifts often come from someone just trying to fix a minor bug at 2 AM. Simple as that.

International Flavors: What the World Calls the Symbol

While English speakers are content with the literal at sign, other cultures have gotten incredibly creative. Names for the symbol often reflect food, animals, or local humor. These names usually describe the spiral shape of the character, leading to a global zoo of nomenclature.

In Italy, for example, the symbol is called chiocciola, which means snail. In many Germanic and Dutch-speaking countries, it is an apenstaartje, or monkeys tail. Perhaps the most delicious name comes from Israel, where it is often referred to as a shtrudel, after the spiral layers of the pastry. Understanding the history of the at sign reveals how a cold, logical piece of code is interpreted so warmly through the lens of local culture.

The Keyboard Confusion of 1998

Marcus, an early web designer in London, was helping a client set up their first business email. Back then, keyboard layouts were inconsistent, and the @ symbol was often hidden behind obscure shift combinations that varied from one machine to another.

He spent twenty minutes trying to find the key on a French-imported laptop his client had bought. They tried every combination - Shift+2, Alt+G, even digging into the ASCII character map - but nothing worked on the first three tries.

The breakthrough came when Marcus realized the keyboard was mapped to a legacy Spanish layout. He had to explain to the frustrated business owner that they were looking for an 'arroba,' which was the local name for the character.

Once they found the right key combination (AltGr+Q in that specific case), they finally sent the email. Marcus reported that the client was so relieved they wrote down the shortcut and taped it to the monitor for three years.
