The Origin of the @ sign
If you are like me you spend copious amounts of time wondering about the world around you. Nothing is too trivial. One day I decided to try and find out who created the @ sign. Here are pieces of what I found.
“A commercial at is the symbol @; also called an at symbol, an at sign, or just at, and sometimes mistakenly called an ampersand (& is the ampersand). It is a cursive form of Ä, or Ã , a term of debated origin. It is assigned to Unicode code point
U+0040. Its official ANSI/CCITT name, commercial at, comes from its use in invoices, as in, “7 widgets @ Â£2 ea. = Â£14″. Other names include: about; acosta; ampersat or asperand (compare ampersand); amphora; ape; apothrope; arobase; atgry; atmark; cabbage; cat; cinnabun or cinnamon bun; commercial symbol; cyclone; each; mercantile symbol; rose; schnable; scroll or scroll-a; snail; strudel; these; vortex; whirlpool; chisignuh; whishi-whishi; yurming; or whorl.
@ appears to be the cursive form of Ä, an abbreviation of an unknown word beginning with a. In medieval European manuscripts, abbreviations were generally indicated by drawing a line over or through the letters, as in the common IX for Jesus Christ (see Christogram), or # from
lbfor libra ‘pound’. In the typeface of the Gutenberg Bible, Ä stands for either an or am within words. However, it is not known which particular word gave rise to modern @.
A similar idea is that @ is the abbreviation of the Greek preposition ana (Î±Î½Î¬), which means ‘at the rate of’ when used with numerals, exactly its modern commercial usage.
A more recent idea has been proposed by history in Rome. He claims to have traced the symbol back to the Italian Renaissance in a Venetian mercantile document signed by on May 4, 1536. The document talks about commerces with Pizarro and in particular the price of an @ of wine in Peru, where <@> stood for amphora (Italian anfora; Spanish and Portuguese arroba). The word arroba still means both the @ symbol and a unit of weight (see below). Under this view, the symbol was used to represent one amphora, which was a unit of weight or volume based upon the capacity of the standard terracotta jar, and came into use with the modern meaning “at the rate of” in northern Europe., a professor of
However, @ could be the abbreviation of any word beginning in a, and more than one such symbol was likely in use, but there is no continuous record between any of the possibilities and the modern symbol.
I encourage you to read the entire piece where you can find out what it is called in other languages. For example:
- In Bulgarian it is called ÐºÐ»ÑŒÐ¾Ð¼Ð±Ð° (“klyomba”, means nothing else) or Ð¼Ð°Ð¹Ð¼ÑƒÐ½ÑÐºÐ¾ Ð° (“monkey A”).
- In Basque it is called a bildua (“rounded a”)
- In Dutch it is called apenstaartje (“little monkey–tail“).
- In Spain, Portugal, Mexico, and Brazil it denotes a pre-metric unit of weight. It variates regionally being about 25 pounds, 11,502 kg, in most parts. The weight and the symbol are called arroba. (In Brazil, cattle is still priced by the arroba â€” now rounded to 15 kg). It was also used as units of volume for wine and oil. The arroba is also called the “a comercial” (the ‘commercial a’)
- The French name is arobas or a commercial, and sometimes escargot (“snail“). Other names include queue de singe (monkey-tail) and a dans le rond (a in the circle).
- In Modern Hebrew it is colloquially known as strudel (×©×˜×¨×•×“×œ). The normative term, invented by the Academy of the Hebrew Language, is kruhit (×›×¨×•×›×™×ª), which is a Hebrew word for strudel.
- In Italian it is chiocciola (“snail“), sometimes at or ad (pronounced more often /É›t/, and rarely /at/, instead of /Ã¦t/).
