"Diction" means choice of words. In the post on the "obituary" for the English language just below, you've seen some examples of very poor choice of words. Some people get confused about to, two, and too; there, they're, and their; flaunt and flout.
So here's a PDF of what I call "diction demons": words that often sound alike but have very different meanings. You're welcome to download it and pass it along.
