Ineffective subordination

If a sentence buries its major idea in a subordinate construction, readers may not give the idea enough attention. Express the major idea in an independent clause and subordinate any minor ideas.

Example sentence with editing. Original sentence: Australia's prime minister, who has promised to take action to stop global climate change, swept the election in 2007. Revised sentence: Australia's prime minister, who swept the election in 2007, has promised to take action to stop global climate change.

The writer wanted to focus on the promise to stop climate change, but the original sentence buried this idea in an adjective clause. The revision puts the major idea in an independent clause and tucks the less important idea into an adjective clause (who swept . . .).

Example sentence with editing. Original sentence: The lab attendant noticed a rapid weight loss in the marmosets and recommended a diet with increased fatty proteins. Revised sentence: The lab attendant, noticing a rapid weight loss in the marmosets, recommended a diet with increased fatty proteins.

Example sentence with editing. Original sentence: The lab attendant noticed a rapid weight loss in the marmosets and recommended a diet with increased fatty proteins. Revised sentence: Noticing a rapid weight loss in the marmosets, the lab attendant recommended a diet with increased fatty proteins.

The less important idea (what the attendant noticed) has become a participial phrase, while the important action (the diet change) takes over the independent clause.

Excessive subordination

In attempting to avoid short, choppy sentences, writers sometimes move to the opposite extreme, putting more subordinate ideas into a sentence than its structure can bear. If a sentence collapses of its own weight, occasionally it can be restructured. More often, however, such sentences must be divided.

Example sentence with editing. Original sentence: Our job to stay between the stacker and the tie machine watching to see if the newspapers jam, in which case we pull the bundles off and stack them on a skid, because otherwise they would back up in the stacker. Revised sentence: Our job to stay between the stacker and the tie machine watching to see if the newspapers jam. If they do, we pull the bundles off and stack them on a skid, because otherwise they would back up in the stacker.
