OK - finally some really good news for folks who get confused about grammar and word choices.
But first, some "History for wordies." (Is that a word?)
It seems that according to the English Club, "okay" ranks number 1654 in the list of the mostly commonly used words in the English language.
#1, by the way, is "the." The word "I" comes in at # 11 with "you" at #14.
But where did okay come from?
According to an article I came across today, it dates from the 1800's, when it became a fad in New York and Boston to misspell a word, then abbreviate it and use the abbreviation. OK was the abbreviation for "oll korrect."
Use of the abbreviation was made more popular during the 1840 presidential election. Presidential candidate Martin Van Buren was given the nickname "Old Kinderhook" in reference to the village in upstate New York where he was born. Before long, "Old Kinderhook" was abbreviated to O.K. and Van Buren's supporters formed the O.K. Club.
But what about the word "okay?" According to the Oxford English Dictionary, it was first used in 1895, but it didn't come into common use until the 1930's.
Meanwhile... we all know what OK means. Even my dog and my horse know what OK means.
But what is the proper way to write it? 
- OK
- O.K.
- okay
Any way you choose.
Some style books say NOT to write it out as okay, others say that's OK.
O.K. is a more dated use, but if you prefer it, go ahead and use it.
Isn't that nice? Whichever way you write it, you're NOT wrong!
Oh, but wait a minute. There is one rule: Choose the form you want to use and use it consistently. You can change from one document to another if you crave variety, but stick with one form per document.
