Here’s another word usage bugaboo of mine. I saw a television show recently where a character said he had a pit in his stomach. What he meant was that he had a bad feeling in the pit of his stomach. I’ve heard this mistake before and it grates.
The stomach is mostly empty space, like a hole in the ground. The deepest part of it is the pit. Strong apprehension can cause a tension or uneasy feeling of tightness in the pit of the stomach. One cannot suddenly develop a pit in the stomach since it is always there already. Saying you had a pit in your stomach is like saying you had strands in your hair or a hole in your nostril. Your hair is strands and your nostril is a hole. Unless you meant you just swallowed a peach pit or something like that, stick with a feeling in the pit of your stomach.
