How to pronounce @? What do you mean?

The @ symbol used to have two meanings in English, namely "in" or "unit price". Its former meaning is often used as a synonym for "existence" because its pronunciation is similar to English at. For example, the English note "Wait at school tomorrow morning" became "Wait You @ SchoolMorning". Besides at, there are different meanings, so "@" is often used to indicate the unit price symbol of goods.

Ray Tonlinson, an American computer engineer, established the position of @ in e-mail and gave the symbol @ a new meaning. 197 1, he was ordered to find a format of computer address, which would allow users to send emails conveniently. "@" was selected because it won't duplicate a person's name. In the e-mail address format, "@" separates the person's name from the computer address, so that the file will not be misread when it is transmitted in the network. When used in e-mail address format, "@" sounds a bit like "at", meaning "in …". "@" thus entered the computer network.
