He crept softly down the hall.
The cymbal crashed loudly.
She kissed him passionately.
The baby cried noisily.
Let it not be said that I don’t appreciate a well-placed adverb. Seriously. But there are far more instances when a manuscript can benefit from the removal of adverbs, rather than the addition of them. In three of the four examples above, the adverb is redundant. Creeping is soft, by its very nature. Cymbals are loud, and crashes are loud. Babies rarely cry with noise levels considerate of their surroundings. The kiss? If it’s passionate, show it. One person’s “passionately” is another person’s “abusively,” “lovingly,” “abruptly” or even “roughly.”
Make your adverbs count. Use them sparingly (there’s one!) so you don’t start to rely on them to carry your narrative. If you’re busy telling the reader how something happened, you’re depriving them of the opportunity to see it for themselves.
