I am not the grammar police. I am not the grammar police. I'm not. I resigned when Brendan graduated from high school. But just occasionally, an error that usually skates right by me will drive me up the wall.
Such as, "9 AM in the morning." Think about that for a minute. Do you even know what "AM" actually means? "AM" stands for "Ante Meridian," or (in other words) "before noon." There is really no more redundant phrase spoken than "9 AM in the morning." When you say that, you are saying "Nine in the morning in the morning." Where is that bangs-head-on-brick-wall icon when you need it?
Normally, I couldn't care less...oops. Let's look at that phrase, too. "I COULDN'T care less." Meaning, "my capacity for caring about (whatever it is) is at its lowest ebb." If you say, "I COULD care less," it means that it is possible for you to...well...care less. If you COULD care less, then you obviously care more than the person who COULDN'T care less.
May Santa stuff your stockings with grammar textbooks!
