What is Parallel Structure?

Parallel structure is the use of identical forms of words, phrases, and clauses when linking or listing together various sets of terms or items. The goals of parallel structure are to give each part of a sentence equal weight (i.e. to show that each part of is of equal importance) and to make the sentence in question flow smoothly.

Examples of parallel structures through use of:

  • WordsI went to the store and the mall.
  • PhrasesI went to the store and by the mall.
  • Clauses: I went to the store, stopped by the carwash, and ate at the mall.

Note that in the sentences above, each part of the speaker's activity seems equal in importance, or holds equal weight. The sentences, for example, do not imply that going to the mall was any more or any less important than heading to the store or stopping by the carwash. Every part is equal.

Moreover, the sentences above read smoothly. If a sentence (such as the one below) does not consistently use the chosen structure (words, phrases, or clauses), then the sentence sounds strange.

  • I went to the store, stopped at the carwash, and by the mall

Parallel structure is used in a variety of instances and situations. Some of those include:

  • Comparisons: I like both milk and cheese. I enjoy neither soda nor chocolate.
  • Lists: I bought milk, cheese, and bread.
  • Activities: I ran on the treadmill, lifted weights, and went to an aerobics class.
  • Thesis statements: Video games can have a positive effect on teenager's self-esteem, motor skills, and problem-solving abilities.

There are, of course, many more. The important thing to remember when using parallel structure is that whatever form is chosen (words, phrases, or clauses) must be used consistently throughout the entire list.

Building Lists Using Parallel Structure

Building lists is one of the most common ways in which parallel construction is used. This video goes over the basics of composing lists that follow parallel structure. It also provides a simple test to help writers catch poorly developed lists.

Paired Ideas and Parallel Structure

Often in English, a writer will want to pair two basic ideas to show their relationship. The video below shows how to use parallel structure to most effectively present such paired ideas.
