What is IMK?

As mentioned earlier, you are most likely going to see IMK used as a way to say “in my knowledge.” People use it when they aren’t certain what they are saying is true — Think of an abbreviated short-hand for “to the best of my knowledge.”
You will find this acronym on all corners of the internet (Instagram, Twitter, Snapchat, Facebook, TikTok, and chat platforms like Whatsapp) and in your text messages, most likely in response to a direct question.
Examples:
- The movie starts at 9 pm, IMK.
- IMK, there is no quiz today.
- IMK, Pete Davidson said he was going to run for president.
- This is a vampire squid, IMK.
- IMK, we need to turn over this project by the end of February.
- Bring a jacket, IMK it’s going to rain.
- IMK, he didn’t give a feedback.
When to Use IMK?
If you aren’t certain about something but want to let the person know possibly pertinent information, then it’s the right time to use “IMK.”
Also, make sure you are close with whoever you are sending it to because sometimes it can be perceived as lying and not wanting to take the blame, like “I said IMK, you can’t blame me that you showed up late!”
In addition, though “in my knowledge” sounds formal, the acronym IMK is certainly not, so keep this to your personal texts.
How to Use IMK
You can place this at the beginning or end of the piece of information that you are not sure of. Unlike other acronyms, you don’t have to try to make it read naturally if the person were to say the full phrase. Just tack it on and forget about it (and maybe Google what you just said to make sure you’re right).
Other Meanings of IMK
This is where the real fun starts. As mentioned earlier, IMK has plenty of alternative meanings.
“I must know” is one of those alternate meanings, so instead of being added to a statement, it is paired with a question. For instance, “What is the Wi-Fi password? IMK!”
An even more confusing meaning could be “I’m just kidding” or “Ignore my kidding,” however, this alternate IMK meaning is usually used without any other text and in response to the other person taking something too seriously.
The least likely alternative, but still out there, is “inform me, kid.” We guess if you ever need to sound like an undercover cop who just discovered some juicy secret from a juvenile, you won’t be using this IMK meaning variation that too often.
Examples:
- Red or blue dress for tonight, IMK!! (I must know)
- IMK there is no class today (I’m just kidding – said after convincing someone they are late to class)
- There’s a new crab species? IMK (inform me, kid)
- Was Shelly there? Did she mention me? IMK (I must know)
Final Thoughts
As you can see, the IMK meaning is all over the place. Context clues are going to be your best friend here. It could mean “in my knowledge,” “I must know,” or “I’m just kidding.” Whatever variation you choose, remember that abbreviations, slang terms, and popular acronyms are best reserved for personal messages, online chats, and social media posts.
