In English, the @ sign is officially called “commercial at” because of its use in accounting. The sign means “at the rate of”. For example, “6 widgets @ $2” means 6 widgets at the rate of $2. Today this sign is an emblem of the Web and is used in every e-mail address.
There are several theories of the origins of the @ sign.
- Giorgio Stabile, an Italian scholar, claimed that the @ symbol was used to denote an amphora: a terracota jar used to transport grain, oil and wine. Stabile discovered a letter from a Florentine merchant written in 1536 where the @ sign is used to replace the word “amphora”.
- According to American scientist Berthold Ullman the sign was used by medieval monks to abbreviate Latin word “ad” (at, by, toward) when used next to numerical units.
- In Spanish, French and Portuguese, the @ symbol represented a weight measure (approximately 15kg) and is called arroba (or arobase in French). The word originates from the Mozarabic word for quarter.
In 1971 Ray Tomlinson, the inventor of e-mail, used sign @ to separate two parts of the e-mail address: username and domain. Tomlinson was looking for a symbol which could not be confused with the letters used in a domain- or user name. The fact that the @ symbol is called “at” in English made this choice even more logical. This way, the address used by Tomlinson – tomlinson@bbn-tenexa – means that user tomlinson is at the bbn-tenexa domain. Lastly, the symbol was conveniently already present on computer keyboards because of its previous use in commerce.
The strange form of the sign has led to different associations and names in different languages. You can find some examples below:
