LYK is an acronym for “let you know” or “letting you know.” It’s really common over text, on social media, or in online messaging as a way to let someone know you’ll update them about something later on. It’s basically just a faster, casual alternative to typing out “I’ll let you know.”^{[1]

- Variations include ILYK (“I’ll let you know”) and LYK ASAP (“Let you know as soon as possible”).
- Typically, “LYK” is pronounced letter by letter rather than as a word. It’s rare to hear “LYK” conversation since it’s usually just a texting acronym.

1
Use LYK when you’re making plans with someone. If you’re trying to make plans but don’t quite know your schedule or if you’ll be free at a certain time, you can tell the other person you’ll “lyk” about availability later. For instance:
- Them: “Should we meet up for drinks at 7 or 8?”
  You: “Hmm. Let me check my schedule and I’ll lyk!”
2
Promise someone more information in the future with “LYK.” If you don’t have all the information on a situation yet but plan to find out, you can use LYK to assure someone that you’ll give them an update with more info later. For instance:^{[2]

- Them: “Did you hear back from Robin yet?”
  You: “Nope. I’ll lyk when I do!”
3
Reply to a question with “LYK” if you don’t have an answer yet. When someone asks you a question you don’t know the answer to, you can send back an “lyk” if you plan to get the answer sometime soon. This can apply to chats between friends or even informal work chats with coworkers you’re close to (but it’s definitely a casual acronym, so don’t use it in formal professional writing!).^{[3]

- Them: “Hey, could I get a ride to work with you on Thursday?”
  You: “I think so, but I’ll lyk for sure by tonight!”

1
Offer a casual confirmation of their statement. Most of the time, the best response to “lyk” is just a casual acknowledgement that you’ll be waiting for them to give you more information later on. You can also give a teasing or joking response if you’re good friends or close to them; it really just depends on the situation. For instance:
- Them: “I’ll lyk if I’m free later!”
  You: “Sounds good!”
- Them: “I’ll lyk when I know more!”
  You: “Okay, but don’t leave me hanging! 😉”
2
Follow up after a while if they don’t update you. However, be careful not to pester the other person. Wait a reasonable amount of time for their response, depending on how urgent your question or attempt to make plans was. If they still haven’t responded for a while and you need to get an answer soon, you can text or message them again.
- You: “Wanna see a movie tomorrow night?”
  Them: “Sounds fun, but not sure if I can make it—I’ll lyk!”
  You: “Okay!”
  You (the next morning or afternoon): “Hey, just checking in again! Any update on movie plans?”
3
Give a more professional response to a message from a coworker. As mentioned before, LYK is mainly a casual abbreviation for social media and texting between friends, family, and other people outside of work. Still, you might get an LYK from a coworker you’re closer to and comfortable informally messaging. For instance:
- Them: “I’ll follow up with the client and lyk what they say.”
  You: “Understood! I’ll be working on these proposals in the meantime.”

What does LYK mean from someone you’re dating?

LYK still means “let you know” in the context of dating or crushes. It’s totally understandable to worry if someone you’re interested in or dating says “I’ll lyk” when making plans for a date, but it’s not necessarily a bad sign. If that person gets back to you with times or date options, then “lyk” really did just mean they were busy and didn’t quite know their schedule at the time.
- For instance, say you ask your date to hang out on Friday and they say, “I might have a work thing, but I’ll lyk.”
- If they reply the next day with “Friday works, I’m free!”, that means they really did just need to figure out their plans and are still interested in seeing you.
- Alternatively, if they reply with “Sorry, Friday is a no-go, but I’m free Saturday or Sunday,” that’s still a good sign—they can’t hang out when you suggested, but they’re offering alternatives because they want to see you!

LYK might mean a girl or guy isn’t very interested if they don’t follow up. However, that’s not universal! Every “lyk” you get isn’t a guaranteed sign of disinterest. It ultimately comes down to the individual situation and the effort a person puts into scheduling a date. If they really aren’t interested, they probably won’t put any effort into making plans.
- For instance, if they say “lyk” and then never follow up, or follow up with more vague “IDKs” and “LYKs,” it might mean they’re not interested and trying not to be rude about it.
- Still, if there’s any doubt or uncertainty, it’s better to be upfront! You can politely ask them flat-out if they still want to go out with you.
- It can be disappointing when it turns out that someone isn’t interested—but at least if that’s the case, you got clarity on the situation and can refocus your energy on someone who is interested.

“Lyk” can be a shortened version of “like,” but this is rare. However, “let you know” is still very much the more common meaning behind “LYK.” So, when in doubt, use the context of a person’s message to determine whether they actually mean “like.”
- For instance, “Really lyk this movie im watching!!” is definitely an example of “lyk” meaning “like,” since “let you know” wouldn’t make sense in the statement.
