How to spot and fix those sneaky repetitions that weaken your prose..
Aside from a great one liner, a declaration of love, or a juicy piece of gossip, most people don’t like to hear the same thing over and over. This is doubly true for readers, and repeating yourself in a novel can make your story feel redundant, stale, or even poorly edited.
When you consider a typical novel runs between 80,000 and 100,000 words, it’s no wonder words (and even ideas) get repeated. Some of those words readers don’t notice (such as said) and others stand out even if you only used them once or twice (like antidisestablishmentarianism).
