should I write :
[ 1 ] I am OK
Or
[ 2 ] I am okay
Do they differ in meaning or OK is a shortcut of Okay? When we use OK and okay?
They are just alternative spellings. You can use either.
The origin of the word is rather unclear. One theory is that it is based off a joke abbreviation of "Oll Korrect".
It is often spelled "okay" or more rarely "okey".
It seems the most common spelling now is "okay". Use that spelling.
(Also "I'm" or "I am" but never "Iam")
OK
is more curt, especially in all caps and/or punctuated, whileokay
is softer.
