What is the ’@’ sign called?
Ampersand, asterisk, tilde, comma, parentheses. Most of the commonly used symbols in the English language have particular names associated with them, so we can talk about them without having to say "you know, that squiggly symbol that kind of looks like the letter S." With the emergence of the Internet, and with it, the important role that the ’@’ sign plays in e-mail addresses, this once uncommon symbol now has a lot of people wondering what to call it.
Officially, this symbol is called commercial at. Unofficially, most people seem to refer to it as the at sign or just at. Recently, there has also been a movement to call it the atmark. There are also numerous nicknames for it, including snail, curl, strudel, whorl, and whirlpool.
