There is a word that, according to the Mozilla Firefox browser and various other sources, I consistently spell incorrectly. I know I do it. I even choose to do it. The word is okay. According to some, it should be OK. I don’t know why I have so much trouble with “O.K.” and “OK,” but I do. It allegedly used to stand for “all correct” or “orl korrect” (according to the Oxford English Dictionary, AKA the best reference tool ever !). But the OED also lists multiple entries in which it is spelled “okay.” Even though the preferred spelling seems to be O.K. or OK, depending on where you look, I’m consciously going to stick with okay, because it really doesn’t stand for “orl korrect” to me. And if it did, I would say A.C. for “all correct,” anyway. Since A.C. stands for something else, and O.K. stands for essentially nothing, I’m going to keep using “okay,” for the record.
