What is @ ?

[Tamdang]

We usually see the sign @ in email addresses .For example, dangttam @ yahoo.com. What is the sign @ ? And How do we read it ? Thanks

[nevertheless]

its called "at", you read it just like the preposition. Furthermore, people sometimes use it as a word, for instance: i'm @ home now. But you see it's just like an internet slang

[EnglishFix]

It's called "the at symbol" or "the at sign".
