According to another version, the @ sign was invented by medieval priests to reduce the Latin word of ad, is used as a generic expression denoting the prepositions "on", "in" and the like. The Spanish, French and Portuguese origin of the symbol is associated with the word "arroba" - a medieval measure of weight, which is abbreviated letter @ symbol.
The current official name of the character -"Commercial at». This is due to the fact that one of the meanings of the word is at the preposition "for." And the phrase itself comes from commercial accounts, for example, 5 newspapers @ $ 3 or 80 shares @ 60 cents.
