“One idea to a sentence” is the title of a section in Theodore Bernstein’s The Careful Writer: A Modern Guide to English Usage. It’s also a darned good idea for financial writers.
Bernstein advises this approach for “those kinds of writing in which instant clarity and swift reading, which are other ways of saying quick comprehension, are dominant desiderata.”
Bernstein cites research showing that articles with a shorter average sentence length are more easily understood.
…in other words, a few sentences of three or four words offset some rather long sentences and pulled the average down. Still, although there were some rather long sentences, there were no complicated ones.
This analysis led to the one-idea-per-sentence approach. That’s partly because “Confining a sentence to a single thought will usually reduce the number of words.”
If the folks whose work I edit took this approach, I would spend less time breaking long sentences into two or even three sentences. This kind of editing is an easy way to boost readers’ comprehension.
Of course, I must be careful not to create what Bernstein calls a “splinter.” Sometimes, as Bernstein says, “a writer or an editor ineptly splits a long sentence, then finds himself holding a meaningless splinter like this: ‘The charge came after an assertion by District Attorney Hogan.’ “ This is part of what writing guru Bryan Garner means when he calls for “no brevity without substance.” I think he and Bernstein have similar philosophies about the characteristics of good sentences.
I also tend to favor one idea per blog post. But that’s a topic for another day.
