What does the abbreviation ttyl mean in email

A blast from the past!

"TTYL" is an abbreviation that stands for "Ta-Ta You Later". It's a casual way to say goodbye or farewell in an email, text message, or online chat. It's often used in informal communication, especially among friends or in a playful tone.

In the early days of the internet and email, "TTYL" was a popular abbreviation among online communities, especially in the 1990s and early 2000s. It's still used today, although it's not as widely used as it once was.

So, if you see "TTYL" in an email, it's likely the sender is saying goodbye or signing off, and you can respond with a similar greeting, like "L8R" (Later) or "C U L8R" (See You Later).
