1. Parallel Structure
Balancing Ideas

2. Sentence elements that are alike in function should also be alike in construction. These elements should be in the same grammatical form so that they are parallel.
Using parallel structure in your writing will help with
economy
clarity
equality
smoothness

3. Use parallel structure with elements joined by coordinating conjunctions. (and, but, or, and nor)
Faulty: The committee studied all aspects of the problem-- humane, political, and cost.
Correct: The committee studied all aspects of the problem-- humane, political, and financial.
Faulty: According to my teacher, my composition revealed exceptional creative ability but that I make too many spelling errors.
Correct: According to my teacher, my composition revealed exceptional creative ability but too many spelling errors.
Correct: According to my teacher, my composition revealed that I have exceptional creative ability but that I make too many spelling errors.

4. Use parallel structure with elements in lists or in a series.
Faulty: The captain had a harsh voice, a weather beaten face, and was very stocky in build.
Correct: The captain had a harsh voice, a weather beaten face, and a stocky build.

5. Use parallel structure with elements being compared.
Faulty: Her novel was praised more for its style than for what it had to say. (noun paired with clause)

Faulty: Water-skiing no longer interest me as much as to go scuba diving. (gerund paired with infinitive)
Correct: Water-skiing no longer interests me as much as scuba diving. (gerund paired with gerund)

6. Correlative expressions (both, and; not, but; not only, but also; either, or; first, second, third; and the like) should be followed by the same grammatical construction. Many violations of this rule can be corrected by rearranging the sentence.

7. Place correlative conjunctions immediately before the parallel terms.
Faulty: Mrs. Sayers is not only president of the National Bank but also of the Chamber of Commerce. (Not only precedes a noun, president, whereas but also precedes a prepositional phrase, of the Chamber of Commerce)
Correct: Mrs. Sayers is president not only of the National Bank but also of the Chamber of Commerce.

8. Try It...
The team both felt the satisfaction of victory and the disappointment of defeat.

9. Repeat an article, a preposition, or a pronoun whenever necessary to make the meaning clear.

Before the meeting I talked with the secretary and the treasurer.

10. More Examples:
