“Only” is the most commonly misplaced modifier. Depending where you put it in a sentence, it changes the meaning entirely.
Here is a basic sentence: I read the newspaper. Now let’s play around with “only.”
1. Only I read the newspaper. This says no one else in this house reads it; I am the only one who does.
2. I only read the newspaper. I don’t do anything else with it: I don’t recycle it, I don’t line the birdcage with it, I don’t put it in the bottom of the cat’s litter box.
3. I read only the newspaper. I don’t read books or magazines or anything else, just the newspaper.
4. I read the only newspaper. This town has just one newspaper, so that’s the one I read.
5. I read the newspaper only. This has the same meaning as #3.
The trick with all modifiers is to put them right next to the word about which you want to give more information.
