Homonym: @ (At)
The "@" symbol, commonly called the "at sign," is a character used primarily in email addresses to separate the user's name from the domain name. For example, in the address user@example.com, the "@" indicates that the user is associated with the example.com domain.
In addition to email, the "@" symbol is widely used in social media platforms like Twitter and Instagram to tag or mention users. When you write @username, it notifies that specific user and links to their profile, facilitating communication and interaction within the platform.
