at sign

The at sign (@), which is shorthand for the word "at," has become widely identified around the world due to its use in Internet e-mail addresses and Twitter names. Officially called an "asperand," the at sign separates the recipient's name from the domain name in e-mail; for example, me@mycompany.com.

A Twitter Symbol
The at sign is a prefix to a member's name on Twitter; for example, @BarackObama is President Obama's Twitter name. See Internet address.
