The placement of only as a modifier is more a matter of style and clarity than of grammatical rule. In strict, formal usage, only should be placed as close as possible before the word it modifies. In the following sentence, for example, the placement of the word only suggests that no one but the children was examined:
The doctor examined only the children.
In the next sentence, the placement of only says that no one but the doctor did the examining:
Only the doctor examined the children.
Nonetheless, in all types of speech and writing, people often place only before the verb regardless of what it modifies. In spoken discourse, speakers may convey their intended meaning by stressing the word or construction to which only applies.
