If only writers would place "only" where it belongs, we would all enjoy clarity.
Consider the difference between the spoken and the written word.
Suppose someone says, "I only stopped at three stores today."
In conversation, we commonly understand that the speaker stopped at only three stores.
But in writing, the form "I only stopped at three stores today" means something entirely different. It means that the only thing the person did all day was to stop at three stores.
Misplacement in a sentence of the word "only" produces a meaning different from what the writer intended.
Our business here is to make what we write say what we mean.
When writing the word "only," we need to place it right next to, or as close as possible to, the subject it pertains to.
