PARALLELISM
Parallelism in writing balances a word with a word, a phrase with a phrase, or a clause with a clause, so the parts of a sentence are not only coordinated but grammatically the same, as in the following examples.
"…of the people, by the people, for the people…."
"And for three days and nights this lurid tower swayed in the sky, reddening the sun, darkening the day,...filling the land with smoke." (from Jack London's account of the San Francisco fire).
"Persons attempting to find a motive in this narrative will be prosecuted; persons attempting to find a moral in it will be banished; persons attempting to find a plot in it will be shot." (Mark Twain in The Adventures of Huckleberry Finn)
"It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Light, it was the season of darkness, it was the spring of hope, it was the winter of despair…." --Charles Dickens
PARALLEL STRUCTURE shows your control not only of grammar but also of style. When words, phrases, or clauses within a sentence grammatically match, the result is PARALLELISM.
Parallel structure guides your readers through complex ideas, words, and phrases. In the following examples, notice a balance and consistency in the grouping and form of words, clauses, and phrases.
(Words) Julio was happy, excited, and tired
(Phrases) Prepare for the exam by annotating, by outlining, and by reviewing.
(Clauses) Julio went to school, Jack stayed for football practice, and Tina drove to work.
Notice also that certain emphasizing words like not only/ but also, both/and; either/or, and neither/nor: can alert us to the parallel structure.
I was not only excited, but also confident about the game.
I was both surprised and pleased to hear the good news.
Either Phillip will repair the car, or Marlina will lend us hers.
Neither my brother nor my sister can lend me the money.
Following is an example of faulty parallel structure (or, we might say, no parallel structure) followed by correct parallel structure. Notice that parallelism involves clarity, economy, and smoothness.
The first version wastes words, while the re-write is more direct and consistent in form. Remember that everything has to match, or agree. The error is bolded.
(Faulty) I like running and hiking and to ski.
(Parallel) I like running, hiking, and skiing.
