Internet Slang 101: HELP! What Does The Term LMK Mean?

what does lmk mean

Hello, Shakespeare’s of the world! If you’re reading this, you’re probably yet another Homosapien who is reluctant to step out of the 1800s. Unfortunately, one part of the internet scatters the pieces of the lingo puzzle. Thankfully, another part of the internet puts the missing pieces together. The internet is like an online journal for evolving literature. If you want to understand it, it’s easy.

And you’ve come to the right place. But this is like, a lot. Slangs, abbreviations, acronyms. Where do we begin? In ascending order. Slangs are mostly informal terms. Informally speaking, they can be used by anyone who wants to save time. Try avoiding using slangs while writing literature, since that is a sacred form of speech. Slangs are extremely useful, however, on the text.

Abbreviations are the shortened versions of a word. So ‘BRB’ becomes ‘Be Right Back’ and the ‘United States Of America’ is now the ‘USA’. Acronyms are a form of abbreviation. ‘NASA’ is the shorter form of National Aeronautics Space Administration but can also stand on its own, like NASA. 

Coming back to the topic in hand, what does LMK mean? If you haven’t guessed yet, that’s okay. If there was a scale explaining the difficulty level of abbreviation, it would be something like this:


  1.                                   4.5.        5


G2G.                              LMK.  DGMW


Okay, to let the cat out of the bag,


The abbreviation Of The Day:



The abbreviation ‘LMK’ is actually slanged for ‘Let me know’. It is typically used to convey to someone that you’re expecting a response from them. Asking for an update is so 2007. Now you can ask someone to ‘LMK’ to make things easier. It is a blessing from the internet chat-rooms.

HOW ON EARTH DO I USE LMK (what does LMK mean)?  


Well, that is easy. You should ideally use LMK when you need more information. Here are a few examples.

John: “I have no idea when dad’s flight is landing today.”

John’s Mother: “Okay, LMK.”

Example 2 – 

Iggy: ‘Are you and your family coming for Jennifer’s party on Sunday night? LMK.’

Example 3 –

You get the idea. LMK is shorthand communication to reinstate your interest in an update that you require from someone. It’s almost vernacular to the text universe. What does LMK mean, as an abbreviation means, is that it works with everyone. Young or old. Friend or Acquaintance. Immediate Family or Extended.

Unlike other abbreviations like ‘LOL’ or ‘WTH’, LMK does not come with pre-existing guidelines. Albeit informal, you can use it with anybody and not worry about offending someone. It conveys urgency and necessity in the information required, without making it too obvious.

So you can hold on to your breath. Pace around the room nervously. Feel your heart beat faster. Instead of making the urgency evident in paragraphs of caps lock, a simple what does LMK mean works.
