"The adverb is not your friend."
Adverbs ... are words that modify verbs, adjectives, or other adverbs. They're the ones that usually end in -ly. Adverbs, like the passive voice, seem to have been created with the timid writer in mind. ... With adverbs, the writer usually tells us he or she is afraid he/she isn't expressing himself/herself clearly, that he or she is not getting the point or the picture across.
