Think texting is all about making things shorter? Think again! Texters have created a new English conjunction—”slash”—and they spell it out instead of using the punctuation mark.
Interesting Comments I Have Received but Have Not Confirmed
Mike Boyle made this comment on Twitter: kk doesn't = OK, it's 'OK cool,' very common in Singapore / China as OK = k and cool = 'ku' (?) = k.
D.M. wrote, "In your podcast titled 'How Texting Is Changing English,' you brought up the use of 'kk.' I've been using this for the longest time, but for the life of me, I can't recall where I picked it up. It might have something to do with aviation, based on a theory of origin I've heard.
One origin story I've heard is that it comes from military pilots. Bear with me here. Military pilots, or any pilot really, have to focus on brevity when on the radio. It is said that to acknowledge that something over radio was said, the pilot would cycle their microphone on and off twice, which produced a 'click click' sound. This was then somehow translated to text as 'kk.'
I used to be an avid flight simulator fanatic and I believe I picked up this 'kk' from a community focused on military flight simulators approximately 10 years ago. The use has been around for quite some time and I have also run into it in online gaming as well. Always used to acknowledge or let the narrator know that they were heard and understood. I find that 'ok' is more for accepting, whereas 'kk' is more like "roger, understood."
I hope this helps you with some insight on a possible origin and its use versus 'ok.' "
