Grammar Guru: Words to Avoid

I have always heard that there are certain words that shouldn’t be used or avoided when possible in creative writing. But what exactly are those words? I knew a few of them such as "was" and ly words, but I knew there had to be more, so I did some research and this is what I came up with. Remember this is a guideline only and these words should be avoided most of the time, but it doesn’t mean that you shouldn’t use them at all.
