You know on Mr. Rogers' Neighborhood they have a saying: "You learn something old every day."
So who here knows where "Okay" came from?
I, in my vast experience and knowledge, always just assumed "okay" was the word, and lazy people wrote ok for short. hahaha. I read about it in my local newspaper, and finally looked it up to verify, at the link above.
O.K. is shorthand for "oll korrect" - a sort of joke amongst the newspaper people. "Okay" is simply the wordifying of those initials (I made that word up just now!) - it's called initialism.
I can't believe I was wrong about that, too.
(Yes, there's more.)
I have "always" written "til" in my recipes as a short for "until" - just leaving off the ' at the beginning. Spell check would tell me to write "till," but I happily ignored it, because I knew what it didn't - that I wasn't talking about tilling the earth. But then one day I looked it up. Till is its own word, with its own history, that means the same thing as "until." There is no reason to say 'til; just say till.
At least I'm learning, right?
