Every writer knows there’s always well meaning advice being given for editing a manuscript. Some times it can be employed and other times it’s best to ignore
A piece of domineering, imperious advice often given to writers is to sweep through your manuscripts before submitting them for publications and delete certain words such as. “Just,” “so,” “very,” “truly,” and “really” Gunning for the top slot the most popular prohibition of all is the word “that.”
Some lists included the words “which,” “but,” on the chopping block, too.
I disagree with some of this advice, it’s not a matter of needing the word to be eliminated, it’s a matter of money. The less words, the more profitable to publish. With that said, in some cases, the sentences will sound incomplete or completely wrong without the words “just,” “so,” “very,” and “really” or “that.”
I say read your manuscript to decide what can safely be deleted and what can not. If it sounds incomplete without a word then I say leave it. If there’s no shorter way you can dream up to bring your point across or make your point relevant. Leave it alone. Don’t edit until your story makes no sense.
