Actually, the why is pretty simple: people don’t like
fiction that’s not believable. The how is a little bit longer. This isn’t an
exhaustive list, but here’s an editing checklist of tips for making sure your
story doesn’t make readers think, “Wait, what? That doesn’t make sense.”
Characters and Dialogue
- Go through the story and read through all of one character’s dialogue. Is it consistent? Is it distinct from other characters?
- When you have a child character, ask a teacher or a parent who has a child that age read the dialogue and tell you if it sounds right.
- With a dramatic revelation or a death or a love scene, try reading the dialogue out loud and see if it sounds too cheesy or not.
- If you’re writing a character who speaks only broken English, make sure the vocabulary he knows and the grammar he uses are consistent. What I usually do is figure out what I could say after two semesters of Spanish, and what grammar mistakes I would make at that point. Sometimes I literally translate what the character says into Spanish, then back again.
- Ruthlessly eliminate any information-dumps: places where you used dialogue to tell the readers something they needed to know, but that the character probably wouldn’t say out loud.
- Villains tend to be primary offenders for unrealistic dialogue. If you understand what motivates your villain and makes her personality unique, you won’t have to resort to cliché lines. (See also the evil overlord list. This is hilarious and contains all the cliches you could possibly use with your villain.)
- One simple, yet overlooked question: would my character be smart enough to think of this? Make sure you know your character’s general intelligence level, how perceptive they are about social things, and how good their memory is. Then keep it consistent.
- Have someone involved in theater read over your story specifically for dialogue mistakes. They usually have a pretty good ear for how people talk.
