This is a hot topic.

So many authors have thoughts (all negative) on adverbs.

"If you are using an adverb, you have got the verb wrong." Kingsley Amis

"The road to hell is paved with adverbs." Stephen King

"Empty your knapsack of all adjectives, adverbs and clauses that slow your stride and weaken your pace." Bill Moyers

"Using adverbs is a mortal sin." Elmore Leonard

"Frankly, I wonder who Frank was, and why he has an adverb all to himself." Jodi Picoult

"Every adjective and adverb is worth five cents. Every verb is worth fifty cents." Mary Oliver

You'll note that Charles Dickens is not on this list.  But to be fair, he was paid by the word.  And there is nothing better than an adverb to pad your writing. 

To be clear, Merriam Webster defines an adverb as follows:

 "Adverbs are words that usually modify—that is, they limit or restrict the meaning of—. They may also modify adjectives, other adverbs, phrases, or even entire sentences.

An adverb answers the question when?, where?, how?, how much?, how long?, or how often?:"

Or you can watch this very simple video (Can you spot the adverb in this sentence?)

Why avoid them? 

1. Because they are a distractions.  Use clear simple language rather than make things very, sometimes or never.

It was a very warm day.

It was a hot day.

2. Because they are lazy. Words in "ly" are often the easy way out and are redundant.

"He screamed loudly." By definition a scream is loud.  

How about: "His scream pieced the silence." or "A blood curdling scream echoed across the moor." or "His lips parted in what would have been a scream if he'd been capable of making any noise."

Have I convinced you to search through your WIP and hunt down those adverbs?
