Our goal as writers: clarity.
The best expression of that ideal I've ever heard came from the Roman rhetorician Marcus Quintilianus (35-100 A.D.):
"We should write, not so that it is possible to understand us, but so that it is impossible to misunderstand us."
I am convinced that the writers of the following examples of garbled prose knew exactly what they wanted to say. However, they lost their way, thus leading us astray.
Consider this, from a New York Times profile of David Zaslav, CEO of Warner Bros. Discovery:
"As a young boy in Brooklyn, Zaslav spent Saturday afternoons at the movies with his father, who worked for the family's plumbing business, now called Zaslav & Sons, while attending law school at night."
Say what?
Who was in law school, father or son? The writer unconsciously trips up the reader for a moment, causing confusion — a cardinal sin in writing. Reading further, we learn that it was the son.
