Lesson Transcript
Instructor: Angela Morris

Angela has taught for Language Arts for 12 years and holds a master's degree in Literacy.

This lesson will explain what parallel structure is and present examples of it. It will also provide you with direction on how to use this literary technique and how to find and fix issues with parallel structure.


'If you can't fly, then run. If you can't run, then walk. If you can't walk, then crawl. But whatever you do, you have to keep moving forward.' Martin Luther King Jr. is credited with this infamous quote, but what makes it appealing to the reader? Is it his use of repetition, with the word, 'can't?' What about the certain rhythm that his word choice presents? These techniques are what make this quote a great example of parallel structure.

Using the same pattern of words to show that two or more ideas have the same level of importance is the definition of parallel structure.

Parallel structure is repetition of a certain form, which provides balance and clarity in your writing. It can also be used as an effective technique by highlighting important information or as a way to emphasize powerful points in your writing.


Let's take a look at a basic example of a sentence that uses parallel structure.

  • 'Louise will swim, bike, and run this weekend at her triathlon.'

All three verbs in this sentence are in the same tense, or form. This creates a smooth flow to the sentence as opposed to the one below, which is lacking in parallel structure.

  • 'Louise will be swimming, then bike, and run this weekend in her triathlon.'

The use of 'ing' in the word 'swimming' does not match the other verb forms in the sentence. Below is another example of parallel structure:

  • 'Daniel spent his Sunday afternoons cooking chili, watching football, and napping.'

This example is not parallel structure:

  • 'Daniel spent his Saturday afternoon cooking chili, then he watched football, and took a nap.'

In addition, in parallel structure, it is important to group similar ideas and items when you have short phrases that can be put together. Take a look at the example below.

  • 'Joseph bought a jacket. Joseph bought a pair of shoes. Joseph also bought a tie.'

These three sentences are all dealing with the same topic, and can be combined using parallel structure.

  • 'Joseph bought a jacket, a pair of shoes, and a tie.'

All the items in this example are nouns. Also remember that commas are placed after each noun with the exception of the last item.

Using Parallel Structure

When you combine two or more phrases or clauses, you will use a coordinating conjunction. Remember that conjunctions are words like 'and,' 'or,' 'but,' 'yet' and 'so' that connect two parts of a sentence.

You can also use correlative conjunctions to combine two phrases or clauses. Correlative conjunctions come in pairs, such as 'not only' and 'also', 'or' and 'neither', 'if' and 'then'. You will need to have equal grammatical units after both parts of the conjunction.

Parallel Structure is also important in a displayed list of items.

Fixing Problems with Parallel Structure

So, how can we fix grammatical errors with parallel structure? One of the easiest and most effective proofreading techniques is to simply read a piece of writing out loud. Hearing the flow of the sentence structure oftentimes reveals a lack of continuity in writing, and an error in parallel structure may be to blame.
