All writers make mistakes, certainly including me. It's better to spot your own instead of having a reader do it.
You'll find a few examples, listed below, that challenge you to correct them.
One of the most common mistakes? Writing that does not say what it means:
"As president of the Kennel Club, his poodle had to be perfectly groomed."
Peruse that sentence and you're likely to conclude that the president of the Kennel Club is a poodle.
Hardly.
The first word after Kennel Club has to be "he." That's because "president" needs immediate identification. And it certainly isn't "his poodle."
The problem?
