6-PLACEMENT OF MODIFYING WORDS, PHRASES, AND CLAUSES
The way you place modifying words, phrases, and clauses within a sentence will have a dramatic impact on the overall quality and clarity of a sentence. Modifiers, whether they are single words, phrases, or dependent clauses, should be placed as close as
possible to the word or idea they modify.
