Have you ever been texting someone and they reply with just “K”? You might have stared at your phone, wondering if it’s a typo, a lazy “OK,” or worse—if you’ve upset them. Texting shorthand can be tricky, and “K” is one of the most misunderstood.
Quick Answer:
“K” means “OK.” It’s a casual and sometimes indifferent way of acknowledging a message. Depending on context, it can be friendly, neutral, or slightly curt.
🧠 What Does K Mean in Text?
The letter “K” is simply a shortened version of “OK.” It’s used to show that you’ve received and understood a message.
While “OK” feels neutral or polite, “K” can sometimes come across as abrupt or passive-aggressive, especially in sensitive conversations.
Example:
- A: “Hey, I can’t make it to lunch today.”
- B: “K”
In this context, B’s reply is neutral but could be perceived as slightly dismissive.
In short:
K = OK = Acknowledgment of a message, casual or brief.
