Horrible Homonyms: What Your Spell Checker Won't Tell You

"Homonyms are devilish things.  They are, of course, words that sound alike—and may even be spelled alike—but have totally different meanings.

For a writer, they can be like poisonous vipers.  Misuse of a homonym can ruin an otherwise literate document.  A reader, noticing homonym errors, may simply stop reading.  Whether in business documents, fiction or personal correspondence, a poorly chosen word—quite frequently a homonym—can be deadly."
