ADVERB POSITION AND MEANING
The position of the adverb can affect the meaning of the sentence. The most common error involves misplacing the adverb only. Make sure that the adverb position conveys what you intend to say.

Unclear: She frequently calls the magazine editor. (Does she call the magazine editor more frequently than anyone else? Or does she simply call the editor many times [frequently]?)
