If you’ve ever received a message that simply said “K”, you probably paused for a moment wondering if the person was mad at you. I remember the first time someone replied “K” to a long paragraph — I thought they were annoyed… or done with the conversation. But over time, I realized K can mean different things, depending on tone, context, and your relationship with the person.
In this guide, you’ll learn the exact meaning of K in texting, when it’s polite, when it’s rude, and how people use it across social media and messaging platforms.
🧠 What Does “K” Mean in Texting?
In texting, K means “OK.”
It’s a super-short, one-letter acknowledgment used to show that the message was received or understood.
But there’s a catch…
“K” can also feel cold, blunt, or passive-aggressive, depending on the situation.
✔ Simple Definition:
K = OK = I got it / understood / fine

“Be there in 5 min.”
“K.”
👉 In short:
K = OK, but shorter — sometimes polite, sometimes rude depending on tone.
