Any word you have to hunt for in a thesaurus is the wrong word. There are no exceptions to this rule.There is always an exception to any writing rule. Still, I think Mr. King is right almost all the time on this one.
Someone else1 said that the problem with looking up synonyms in a thesaurus is that you should be developing figurative or expressive language of your own, which is going to be better than any synonym, because it is fresh, and it grows organically out of the voice of the work.
1. Benjamin Franklin, Abraham Lincoln, Mark Twain, Albert Einstein, Adolph Hitler, or an Old Chinese Proverb, I forget which.
