Parallelism in Writing
For your work to be easily read — and, in some cases, for it to be coherent — using parallelism is important. This helps you give equality and balance to separate the points you make.
Puzzled? Not to worry. Understanding parallelism isn't as difficult as it may seem. You simply write all the similar parts of a sentence in the same way. If you've used two nouns, you don't suddenly switch to a gerund. If you've used verbs that have a certain tense, you don't suddenly change tenses. If you begin in one voice, you don't suddenly switch to another voice.
Take a look at some of the examples that follow, and you'll get a clearer understanding of what parallelism is and how important it is in your writing.
Parallelism Problem #1: Items in Pairs or in a Series
When naming items, you should present them all in the same way. Look at this problem sentence:
Here is the problem viewed one way:
Here is the problem viewed another way:
All the verbs are now in the same tense; all verbs are now —
This famous line uses parallelism effectively:
The following example shows the incorrect use of parallel items in a series when a colon is used:
Here's the problem viewed one way:
Here's the problem viewed another way:
Here's the repaired sentence that's now parallel:
Parallelism Problem #2: Clauses
When you're using more than one clause, keep the same voice and use the same type of introduction in each. Here's the problem sentence:
Here's the problem viewed one way:
Here's the repaired sentence that's now parallel:
Now look at this problem sentence:
This is one way to look at the problem:
Or you can look at it this way:

Parallelism Problem #3: Placement
Items in a series should be placed in similar locations. Take a look at this problem sentence:
Let's look at the problem:
Here's the repaired sentence that's now parallel:
Parallelism Problem #4: Placement of Emphasis or Chronology
If the items in a list have different degrees of importance or if they occur at different times, you should order them according to their emphasis or chronology. Look at this problem sentence:
Now, identify the problem:
Here's the repaired sentence that's now parallel:
In writing your sentence this way you've built up to the climax (the worst problem — death). You might also include a word or phrase before the last element to add to the buildup; for example, you could word the sentence like this:
Parallelism Problem #5: Missing Words
Be sure to include all the words you need for each item in your sentence. Look at this problem sentence:
Identify the problem:
Here's the repaired sentence that's now parallel:
Parallelism Problem #6: Unclear Meaning
Include all the words necessary to indicate the items to which you're referring in the sentence. Look at this problem sentence:
Identify the problem: Did Gail talk with one person who was a senior and who was interviewing for the job, or with two people — one of whom was a senior and one of whom was interviewing for the job?
Here's the repaired sentence that's now parallel:
Sometimes you may deliberately repeat certain elements of your sentence, as in this example:
That sentence is fine the way it is, but to add emphasis to the cuts, you might choose to write it this way:
Parallelism Problem #7: Too Many Words
You don't need to repeat the same introductory word if it applies to all of the items in your list. Look at this problem sentence:
Identify the problem:
Here's the repaired sentence that's now parallel:
The same preposition relates to each date, so there is no need to repeat it.
Parallelism Problem #8: Too Few Words
If different prepositions apply to items in a series, be sure to include all the prepositions. Look at this problem sentence:
Identify the problem:
Here's the repaired sentence that's now parallel:
The beginning preposition
Parallelism Problem #9: Parallel Sentences
To add emphasis or smoothness, construct your sentences in a parallel way. Look at this example:
Identify the problem: Actually, there's no grammatical problem with the sentences, but they can certainly be improved by being written in a parallel manner.
Here are the repaired sentences that are now parallel:
Tips for Parallelism
If a lack of parallelism is often a problem in your writing, try the following tips:
Look for -
ing or -ed constructions.Look for constructions beginning with
it, that, to , andyou .Look for constructions beginning with the same preposition.
Look at the voice (active or passive) used in the constructions.
Check to see if one of the constructions is more important than the others; if so, place it last.
If you've used a correlative conjunction, check to see if you have its partner (e.g.,
either … or ).
If you have items in a series, write them down in a column. Look for common elements in two parts of the series, and then convert the other items so they'll be formed in the same way. Sometimes your ear is more reliable than your eye. Good writers read their material aloud and listen for words and phrases that aren't parallel.
