I've noticed, though, that each editor has pet issues she tends to focus on. I had one editor who insisted on striking every instance of the word “that” introducing a dependent clause after a verb of sensation or thought. For example, if I wrote:
Henrietta thought that she'd never recover from Harold's treachery.
This editor would revise the sentence as:
Henrietta thought she'd never recover from Harold's treachery.
I agree the two sentence are equivalent in meaning, and the second is more concise than the first. However, sometimes the rhythm of a sentence requires the additional beat of that extra word. Furthermore, I like some variety in my sentence structures. So I accepted most of her edits, but retained a few “thats” where they seemed to fit.
Anyway, my most recent line editor really had a bee in her bonnet concerning “independent body parts”, often abbreviated as IBP.
In case you've never met the dreaded IBP, this term refers to sentences where some part of a character's body becomes the subject of an action verb. For example:
Her eyes followed him as he strode across the room.
His fingers crept up her thigh and under her skirt.
His tongue poked rudely into her mouth.
Some novice authors overuse this kind of sentence, often to the point of silliness. Because of this tendency, editors have become hypersensitive to these constructions, brandishing their red pen whenever one appears.
However, there is nothing a priori wrong with using a body part as a sentence subject in this way. This is an accepted category of figurative language. It even has a name:synecdoche. Synecdoche is the practice of referring to a part when you mean the whole, or vice versa.
Sentences that are labeled as IBP are not intended to be construed literally. Of course her eyes stayed in her head as he walked across the room – no reasonable reader would think otherwise. Yes, most likely he was in control of those fingers – they weren't acting on their own - but the synecdoche focuses the readers' attention on the stealthy progress of those digits, perhaps even as their owner continues to converse in a normal way.
An occasional “IBP” sentence is not a flaw, in my opinion. When I construct my paragraphs, I do so deliberately, with an eye to diversity and flow. The alternative to using IBP is often to have every sentence beginning with a name or pronoun. This gets boring after a while.
The so-called rule about avoiding IBPs may be helpful to novice authors. The trouble is, it's really not a rule, anymore than the guidelines about avoiding passive voice are rules. English is a gloriously rich language with an enormous repertoire of sentence structures and rhetorical devices. An accomplished author should not shy away from using the ones that she believes her story needs.
