What is Parallelism? Definition, Examples of Parallel Structures in Writing

Parallelism definition: Parallelism is a grammatical term for arranging words of identical or equivalent syntactical constructions in corresponding clauses, phrases, lists, etc.

What is Parallelism?

What does parallelism mean? Parallelism is a grammatical term for arranging words with syntactically accurate structure. In other words, parallelism refers to making sentences have the same, or parallel, structure.

Parallelism is essential to proper writing (and speaking, for that matter).

Examples of Parallelism:

Here is an example with incorrect parallel structure:

  • I like to fish, swimming, and to hike.

In this example, the list series does not use parallel structure. The terms are not parallel. There are two infinitives (to fish, to hike) and one gerund (swimming). This sentence is grammatically incorrect.

Here is an example of parallelism with the correct parallel structure:

  • I like fishing, swimming, and hiking.

In this example, the list uses a parallel structure. The terms are parallel—all three are gerunds. This sentence is grammatically correct.

The Function of Parallelism

Paralelism and parrallelismWhat is the purpose of parallelism? Parallel structure is paramount in good writing. Without it, writing is awkward.

Parallel structure improves coherence and consistency. Allow the following parallelism examples to illustrate.

Poor Structure:

  • To build a tree house, my dad purchased some nails, lots of wood, and rebar.

Parallel Structure:

  • To build a tree house, my dad purchased nails, wood, and rebar.

The difference between the two sentences exists in the adjectives. Is the first sentence able to be understood? Yes. Does the second sentence have better coherence and consistency? Yes.

If a writer uses adjectives in a list to describe a noun, he should use an adjective to describe every noun in the list. Or, like the second example, remove the adjectives altogether.

Parallelism in Grammatical Structures

As we said above, parallelism is essential for clear, concise writing. This applies across a number of different grammatical units like lists, phrases, clauses, etc.

Here is a list of different parallel example structures.

Parallel Structure in Lists

What is Parallelism in Literature?

What does parallelism refer to in writingExamples of parallelism in literature: One of the most detailed examples of parallel structure in literature exists in the opening paragraph of Charles Dickens’ A Tale of Two Cities.

These lines model antithesis but in order to do so must also use accurate parallelism.

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, we had everything before us, we had nothing before us, we were all going direct to Heaven, we were all going direct the other way – in short, the period was so far like the present period, that some of its noisiest authorities insisted on its being received, for good or for evil, in the superlative degree of comparison only.

Beautifully, Dickens models appropriate parallel syntax. Perhaps that is one reason why these opening lines are so well known—their parallel nature makes them easier to recall.

Looking closely, you can see that each antithetical clause has the same number of terms and is the same subject matter.

Dickens utilizes parallel structure here to further his text’s argument regarding the “two cities” that exist together but completely separate.

Summary: Parallelism Literary Definition

Parallel structure is the repetition ofDefine parallelism in literature: The definition of parallelism in literature is the use of identical or equivalent syntactic constructions in corresponding clauses and phrases.
