If you are a beginning writer you will have heard all of these. Where they originated is hard to know but, as Anne R. Allen points out in this post, they are nonsense. She gives examples of where great writers were not only unaware of them, but when they ‘broke’ them, the result was brilliant writing that was admired by critics and readers alike.
At the end of the post Anne very generously provides a list of places to submit your writing for publication and or contests with valuable prizes. The two together offer excellent value which I’m happy to share.
