Extract:

Of all the parts of speech, then, prepositions (and their accompanying nominal phrases) most often work against tightness, compression, and clarity in poetry. Lines needn’t be stripped down as far as I have taken this one, but on almost every level, particularly in early drafts, finding prepositions and prepositional phrases, identifying the underlying verb, defining the actor performing that action, and restructuring accordingly may at least present new alternatives for expression.
