Meaning & Definition
TTYL stands for “Talk To You Later.”
It is an informal abbreviation used to end a conversation politely while suggesting that you’ll continue talking another time. Rather than saying goodbye forever, it tells the other person that you expect to chat again.
Simple Definition
TTYL means:
- We’ll talk again later.
- I’m leaving for now.
- See you later.
- I’ll message you another time.
It doesn’t usually indicate anger, frustration, or disinterest. Instead, it’s a friendly way to end a conversation.
Example

You: No problem, TTYL!
Person A: I’m heading to work now.
Person B: Good luck! TTYL.
Unlike a permanent goodbye, TTYL leaves the conversation open for the future.
Background
TTYL became popular during the early days of internet chat rooms, instant messaging platforms, and text messaging.
When mobile phones had limited keyboards and text messages often had character limits, people shortened common phrases into abbreviations to save both time and space.
Popular abbreviations from that era include:
- LOL – Laugh Out Loud
- BRB – Be Right Back
- IMO – In My Opinion
- IDK – I Don’t Know
- TTYL – Talk To You Later
Even though smartphones now have full keyboards and voice typing, these abbreviations continue to be widely used because they’re fast, familiar, and easy to understand.
Today, TTYL appears across nearly every messaging platform and remains one of the classic internet acronyms that has stood the test of time.
