1. What Is Parallelism?

Parallelism, also known as parallel structure, is a grammatical concept that involves using the same pattern of words or grammatical forms within a sentence to express ideas that are of equal importance. It ensures that sentence elements—such as words, phrases, or clauses—are balanced and congruent, making the sentence more organized, clear, and aesthetically pleasing.

In essence, parallelism functions as a symmetry device in sentences. It aligns similar ideas or parts of a sentence through consistent grammatical form, which helps the reader grasp relationships and contrasts more easily.

For example, in the sentence:

She likes reading, writing, and biking.

the three activities—reading, writing, and biking—are presented in the same grammatical form, demonstrating parallel structure.

Classification and Function of Parallelism

• Structural Classification: Parallelism can involve words, phrases, or entire clauses.
• Functional Role: It provides rhythm, balance, emphasis, and clarity in writing and speech.

Contexts Where Parallelism Is Used

• Lists and series
• Comparisons and contrasts
• Correlative constructions
• Compound sentences
• Balancing ideas in persuasive or descriptive writing

2. Structural Breakdown of Parallelism

At its core, parallelism involves maintaining consistency in grammatical structure across related parts of a sentence. Understanding the structural elements helps writers craft balanced sentences.

Here are the key components:

Elements of Parallel Structure

Component	Description	Example
Words	Single words that follow the same grammatical pattern	She runs, jumps, and swims.
Phrases	Groups of words that function as a unit in a sentence, in the same grammatical form	He is interested in reading, writing, and drawing.
Clauses	Complete ideas with a subject and predicate, balanced in structure	What you said was clear, what I heard was confusing.

Patterns of Parallelism

Common patterns include:

• Verb + Verb + Verb: She enjoys singing, dancing, and playing.
• Noun + Noun + Noun: The project requires dedication, creativity, and patience.
• Adjective + Adjective + Adjective: It was a long, exhausting, and frustrating day.
• Phrase + Phrase + Phrase: He is responsible for managing the team, preparing the reports, and conducting meetings.
• Clause + Clause + Clause: The teacher said that students should study hard, that they should participate actively, and that they should respect others.

3. Types and Categories of Parallelism

Parallelism manifests in various forms, depending on sentence structure and intent. Here are the main categories:

3.1. Parallelism in Lists and Series

This is the most common form; it involves items in a list or series sharing the same grammatical form.

Example:

Incorrect	Correct
She likes to swim, biking, and to run.	She likes swimming, biking, and running.
The coach told the players to be punctual, respectful, and to work hard.	The coach told the players to be punctual, respectful, and diligent.

3.2. Parallelism in Comparisons

Used to compare two or more ideas, maintaining balance between elements.

Example:

She is smarter than her brother is.

vs.

She is smarter than her brother.

Both are correct, but the first emphasizes the comparison explicitly.

3.3. Parallelism with Correlative Conjunctions

Correlative pairs (both/and, either/or, neither/nor, not only/but also) require parallel structure for clarity and correctness.

Example:

Incorrect	Correct
She is not only intelligent but also hardworking.	She is not only intelligent but also hardworking.
Either you come now or you stay here.	Either you come now or you stay here.

3.4. Parallelism in Compound Sentences

When combining two independent clauses with coordinating conjunctions (and, but, or, nor, for, yet, so), maintain parallel structure for clarity.

Example:

She wants to learn French, and she wants to travel to Paris.

vs. (incorrect):

She wants to learn French, and traveling to Paris.

3.5. Parallelism in Balance and Emphasis

Parallel structure can be used to emphasize two ideas equally, often with paired phrases or clauses.

Example:

What you get is a better life and a brighter future.

Many writers fall into traps that compromise parallel structure. Here are some frequent errors and solutions:

6.1. Mixing Different Grammatical Forms

Incorrect	Correct

8. Advanced Topics in Parallelism

8.1. Parallelism in Complex Sentences

In complex sentences containing multiple clauses, maintaining parallel structure can be challenging but is crucial for clarity and style.

Example:

While she was cooking, he was cleaning, and the children were playing outside.

All clauses follow the same pattern, enhancing the sentence’s rhythm and coherence.

8.2. Parallelism with Gerunds and Infinitives

Deciding whether to use gerunds (-ing form) or infinitives (to + verb) in parallel structures depends on the verb and context. Some verbs are followed by gerunds, others by infinitives, and some accept both but with different meanings.

Verb + Gerund	Verb + Infinitive	Examples
enjoy, suggest, avoid	hope, decide, plan	She enjoys swimming, dancing, and singing. They suggested going to the museum. He hopes to travel soon. We decided to leave early.

8.3. Parallelism in Stylistic and Rhetorical Devices

Parallelism is often used in speeches and literature to create rhythm, emphasize ideas, and persuade audiences.

Example:
