TTYL stands for Talk to you later. TTYL stands for talk to you later. It's a casual sign-off at the end of a text or chat, meaning bye for now and we'll pick this up another time. It doesn't promise a specific time.

## What TTYL means

TTYL is short for talk to you later. [Oxford Learner's Dictionaries](https://www.oxfordlearnersdictionaries.com/definition/english/ttyl) labels it informal and describes it as something you use when ending a message to someone on social media and similar places. [Merriam-Webster](https://www.merriam-webster.com/dictionary/ttyl) lists lowercase ttyl as the main form, with TTYL as a variant.

It's a goodbye that leaves the door open. TTYL says the conversation is over for now, nothing is wrong, and you expect to talk again. It's friendly, quick and very low pressure. It doesn't commit to a time, so "later" can mean tonight, tomorrow or whenever you next have something to say.

Most of the time it's sincere. Occasionally it's a polite exit: a way to wrap up a conversation that has run its course, or one you'd rather not continue. And in a joking context, a sudden "ttyl" can mean "I'm leaving this conversation because of what you just said", the way someone might walk out of a room for comic effect.

**A real goodbye for now**
- You expect to talk again
- Nothing is wrong
- Example: gotta run, ttyl

**A polite exit**
- The chat has run its course
- Soft way to stop replying
- Example: ok, ttyl

**A joke walkout**
- Reacting to something outrageous
- Played for laughs
- Example: you put ketchup on that? ttyl

*Almost always friendly. The third one is a bit, not a real goodbye.*

## Where TTYL comes from

TTYL is older than most people assume. The [Oxford English Dictionary](https://www.oed.com/dictionary/ttyl_v) says its earliest evidence for TTYL comes from 1988, in a source titled Some Various Semi-drastic Omega Bugs. In other words, people were typing it to each other long before smartphones, Instagram or TikTok existed.

It took a long time for dictionaries to catch up. The OED's entry history says TTYL was first published in the dictionary in 2016. Interestingly, the OED classes it as a verb rather than an interjection. [Dictionary.com](https://www.dictionary.com/browse/ttyl) gives its origin simply as its use in digital communications.

Its sibling [BRB](/glossary/brb) has a similar story: the OED's earliest evidence for BRB also dates to 1988, and that entry was first published in 2016 too. The two belong to the same generation of chat shorthand, made for typing quickly to someone who was online at the same moment you were.

## How people use TTYL on social media

TTYL is a closing line in private conversations: texts, Instagram and Snapchat [DMs](/glossary/dm), WhatsApp, Discord, and work chats among people who keep things casual. It almost always comes last, often after a reason: "gotta go to class, ttyl."

It also appears in public, but differently. On X and [Threads](/platform/threads), "ttyl" can close a post announcing a break, as in "logging off for the weekend, ttyl". On [TikTok](/platform/tiktok), it shows up in comments as the joke walkout. On LinkedIn, a sign-off like "Talk soon" fits better.

Some example messages, written for this page:

- With a reason: "boarding now, ttyl"
- Ending a long chat: "ok I need to sleep, ttyl"
- To a coworker who texts casually: "heading into a meeting, ttyl"
- With a plan: "ttyl, I'll call you after dinner"
- Logging off publicly: "phone's going in a drawer for the weekend. ttyl"
- Joke walkout: "you've never seen Star Wars? ttyl"
- Soft exit: "sounds good, ttyl"

Oxford Learner's gives a model of how it's used, a short sign-off along the lines of okay, I have to go, bye, TTYL. That's the pattern: a reason, a goodbye and the abbreviation, all in a few words.

You'll also see the full phrase written out, "talk later", or close cousins such as ttys for talk to you soon. Capitals don't change the meaning. Lowercase is more common in personal chats, and TTYL in caps reads a little more emphatic, like a wave on your way out the door.

## What TTYL means from a friend, a crush or a coworker

From a friend, ttyl is a plain goodbye. They're busy, and they'll be back. Nothing to read into.

From a crush, it depends on what came before. "ttyl" after a long, lively chat is a natural pause, and they'll probably reappear. A curt "ok ttyl" right after you said something that fell flat might be a polite exit. If they add a reason or a plan, like "ttyl, good luck tomorrow", it's a warm sign.

From a coworker, it means they're stepping away from the conversation, usually to do something else. If you still need an answer from them, say so before they go: "before you go, can you send the file?"

## How to reply to TTYL

Keep it short. TTYL closes the conversation, so the polite move is to close it too: "bye", "later", "talk soon". If there's something you still need, mention it in one line. Don't start a new topic right after someone says ttyl, unless it's urgent.

**What do you want to happen next?**
- Just say bye → Mirror it: "ttyl" or "later"
- Make sure you talk again → Add a time or a hook: "ttyl, call me after work?"
- Wish them well → Add a kind line: "ttyl, good luck on the exam"
- Get one last answer → Ask quickly: "wait, before you go, is 7 still good?"

Not sure whether it was a real goodbye or a polite exit? Reply the same way either way. A short, friendly sign-off works for both, and it leaves the other person free to come back when they're ready. Chasing a ttyl with several more messages tends to feel like pressure, even when it's meant as enthusiasm.

Some replies for different situations:

- To a friend: "later, have fun"
- To a friend, with a plan: "ttyl, text me when you're home"
- To a crush: "ttyl, this was fun"
- To a crush, a bit bolder: "ttyl, and I'm holding you to that coffee"
- To a coworker on Slack: "Sounds good, talk later."
- To a coworker when you still need something: "Before you go, can you approve the draft?"
- To a joke walkout: "come back, I can explain"

On Snapchat and Instagram, "ttyl" back, or simply a like on their message, is enough. Over text with family, a full "talk to you later" feels warmer. In work chats, plain language beats slang. If you're the one leaving and want to look offline afterward, it's worth knowing how [activity status on Instagram](/blog/how-to-turn-off-active-status-on-instagram) works, so you don't appear active right after saying goodbye.

## When not to use TTYL

TTYL is casual. In emails to clients, notes to a manager or replies to customers, write "Talk soon", "Speak later" or "Thanks, I'll follow up tomorrow" instead. Those say the same thing with a little more care.

Watch the timing in serious conversations. A friend who has just shared something painful may feel brushed off by a quick ttyl, even if you genuinely have to go. Say why, and say when: "I have to run to work, but I'll call you tonight. I want to hear the rest."

And don't use it as a promise you won't keep. If you don't plan to talk later, "bye" or "take care" is more honest. Brand accounts can use ttyl in a playful post about logging off, but not as a sign-off to a customer whose problem isn't solved yet.

**TTYL is fine when**
- [ ] The chat is casual and has reached a natural pause
- [ ] You actually expect to talk again
- [ ] The other person isn't in the middle of something serious
- [ ] It isn't a client email, a manager note or a support reply
- [ ] Anything they're waiting on from you is already answered

## TTYL compared with BRB, TTFN and other sign-offs

| Sign-off | Stands for | How long you'll be gone |
| --- | --- | --- |
| TTYL | Talk to you later | Until the next conversation |
| BRB | Be right back | A few minutes, then you'll return |
| AFK | Away from (the) keyboard | A while, common in gaming |
| TTFN | Ta-ta for now | Until later, with a British, playful tone |
| HMU | Hit me up | Until they contact you |

The key difference from [BRB](/glossary/brb) is that brb means you're coming back to this conversation soon, while ttyl ends it. [Oxford Learner's](https://www.oxfordlearnersdictionaries.com/definition/english/ttfn) lists TTFN as British and informal, a way of saying goodbye in emails and texts, and the same dictionary defines AFK as away from the keyboard, often in gaming. [HMU](/glossary/hmu) hands the next move to the other person, so "ttyl, hmu when you're free" is a common pairing. If you're closing out an argument rather than a chat, [NVM](/glossary/nvm) is the other quick exit.

No. It's a friendly sign-off. It can feel abrupt if someone was sharing something serious, so add a reason or a time in that case.

Close the chat back with something short like "later" or "talk soon". If you still need something, ask in one quick line.
