Have you ever been scrambling to guess what a new slang term means? “IMK” is an informal way of expressing an idea without being 100% positive it’s correct. In this guide, we’ll fill you in on what the acronym means in texting and on social media, as well as alternative slang terms you can use instead.

Learn to Use “IMK” in Texts and Social Media

The acronym “IMK” stands for “In My Knowledge.” It’s an informal way of saying you’re pretty confident but not entirely sure the information you're sharing is correct. It’s like saying, “As far as I know,” “As far as I’m aware,” or “To the best of my knowledge…”

   “IMK” is an acronym for “In My Knowledge.” When you see “imk” in a text from a friend or on places like TikTok or Instagram, it usually means the sender is pretty confident about their answer but not completely sure. Social media marketing expert Macy Olalia says that it's also a nice way of saying that you're not claiming to be an expert. It’s another way of informally saying, “If I recall correctly,” “As far as I know,” or “I think so.”

   • You: “Do you think Justin is coming tonight?”
   • Them: “Imk, I sent him the invite, and he said bet.”
   • You: “Can Mom pick you up after school?”
   • Them: “Imk, she said she was free, so…”

   “Imk” is often mistaken for “Let Me Know.” Due to the similar appearance of an uppercase “I” and lowercase “L,” sometimes “Imk” can be a misspelling of another popular texting term, “LMK” which stands for “Let Me Know.” It’s used to have someone expand on an idea or to request more information.

   • You: “Hey, lmk if you can come over tonight. Got cash to order food!”
   • Them: “I’m just waiting for my mom to come home, so I’ll lyk soon.”

   Use “IMK” to share information that you believe is correct. Want to tell someone you’re pretty sure about something? Send a quick “IMK” message. The information is based on your experience or knowledge, so it’s important to remember that it doesn’t mean it’s 100% accurate.

   • Them: “Yo, I thought you said Justina and Devin broke up?”
   • You: “Imk!! She said she wasn’t talking to him anymore.”

1. 
   Learn how the sender got their information. If you received an “IMK” text, it’s okay not to feel just as confident as the sender does. After all, it’s based on information that’s privy to them—not you. Feel free to ask questions or follow up about how the other person gained that information to help shape your understanding or how you respond to a situation.

   • Them: “Imk the test next week isn’t happening.”
   • You: “Where’d you hear that from?”
   • Them: “I overheard Mrs. Jamison telling the guidance counselor Mr. P will be out for the next two weeks, so they’re trying to find a sub.”
   • You: “Dang. I think I’ll still study tho, just in case.”
