Every thesaurus in the world died a little inside when Stephen King said that. Take King's advice if you like, but please don't throw out your thesaurus. Use it to build an impressive vocabulary, for yourself if not for your characters (you writers out there). And do it because...words are fun! And fascinating. And just plain weird.
I'm not suggesting you become the irritating person at the copy machine, throwing around obscure words in order to sound smart. I only hope you will be aware of the wonderful world of words. If someone uses a word you don't know, look it up. Keep a list of favorite words, unique and special words, and sprinkle them around lightly when you speak and when you write. Like salt, a little goes a long way. And at the very least, you'll up your crossword and Scrabble game.
Here are a few of my recent special words:
augury (a sign of what will happen in the future; omen)
blatherskite (a person who talks at great length without making much sense)
obtund (dull the sensitivity of; deaden)
enchiridion (a book containing essential information on a subject)
In other news, I'm not all that competitive, but I appreciate a hard-earned victory. And although it seems as if we will never reach the end of this pandemic, each day brings us closer to this very hard-earned victory. Stay the course, keep yourselves safe, and we'll meet up again on the other side!
