The “@” symbol, commonly known as the “at sign,” has a long and varied history. Here are some key points about its origins and evolution:
Medieval Manuscripts: The “@” symbol is believed to have originated in medieval manuscripts. Scribes used it as a shorthand for the Latin word “ad,” meaning “at” or “toward.” This helped save time and space when copying texts by hand.

Email Revolution: The symbol gained global prominence with the advent of email in the 1970s.

He chose it because it was not commonly used in names and made logical sense to separate the user’s name from the host computer.
Modern Usage: Today, the “@” symbol is ubiquitous in email addresses and social media handles. It serves as a crucial element in digital communication, identifying specific users or accounts.
