I wonder where in a sentence I should put the word:
only. For example, here are some sample sentences:
I only sell apps to the young person.
I sell only apps to the young person.
I sell apps only to the young person.
I sell apps to the young person only.
In these four sentences, is there any difference between them in meaning?
I believe that the first one puts the meaning of
only on the verb, while the second puts on the noun. The fourth puts the adverb (
to the young person). The third one is either the noun or adverb, likely dependent on the context.
However, as far as I have read many English sentences for my life, most people don't mind where to put
only in a sentence; they just force readers to get what
only points to depending on the context.
So I wonder if there is any rule in the place of
only. Or maybe there is a rule but is too often broken?
