Most of us are guilty of occasionally writing them into our work. They do slip in, especially with eyes. Her eyes swept the room. We all know what that means, but such statements conjure up bizarre pictures and can take the reader right out of the story. Do you see the eyes floating around, controlling the broom? Magic of an unintended kind!
If the person (as opposed to the body part) performs the action, the logic doesn’t jar the reader so much. If body parts, usually hands, feet, or eyes, perform the action, they can create a weird image of the part acting independently of the person. They’re often called flying body parts. Examples:
Her eyes flew upward to the crows. Better, She glanced upward at the crows.
Her hand reached for his. Better She reached for his hand.
Even though readers know what the sentence means, these images can yank them out of the story. Read those body part lines carefully to see if they convey the correct image.
Sometimes, even when the person performs the action, the verb doesn’t work. She shot her eyes at him. It makes the reader wonder how, with a sling shot? She tossed her hand in the air, dismissing him. She can toss her hair but not her hand, or she could wave her hand.
Have you ever been guilty? Have any good examples to share?
