Anybody here ever think about the etymology of the word "ok"?
Supposedly it started as an abbreviation of "oll korrect" and became popular in the 1840's during a fad of abbreviating words a lot like we have "lol" or "omg" today. Then the abbreviation took on its own meaning and became one of the most widely used words to be borrowed by other languages, with a near universal meaning.
Now it even has its own word based on the pronunciation of the abbreviation, "okay".
The equivalent of that would be if the word "lol" became synonymous with laughter over the next 150 years to the point where the words "laugh out loud" look alien and outdated.
I don't know why you're getting down voted. I'm pretty sure I read an article that had both etymologies, with the consensus that no one really knows the truth.
