Parallel Structure
In English writing and speaking, the magic of parallel structure lies in its ability to weave harmony and emphasis into sentences, transforming simple expressions into compelling statements. Also known as parallelism, this stylistic device aligns words, phrases, or clauses by matching their grammatical structures. Beyond mere aesthetics, parallel structure is crucial for clarity, making complex ideas more digestible and arguments more persuasive. Its significance transcends the boundaries of literature and rhetoric, marking its presence in everything from political speeches to everyday communication.
Yet, despite its pervasive importance, mastering parallel structure can be a nuanced challenge for many. Balancing grammatical forms demands a keen eye for detail and a deep understanding of sentence construction. This blog post endeavors to demystify parallel structure, guiding readers through its principles, applications, and the subtle intricacies of its use. By unraveling the complexities of parallelism, we aim to equip you with the skills to elevate your English writing and speaking, ensuring that your messages are heard, felt, and remembered.

Part 1: Understanding Parallel Structure
Definition and Basics
Parallel structure, or parallelism, refers to repeating the same grammatical form within a sentence or series of sentences. This structure alignment enhances readability and rhythm, creating a pattern that resonates with readers and listeners alike.
Components: Parallel structure can apply to nouns, verbs, adjectives, adverbs, phrases, and even entire clauses. The key is consistency; elements in a series should be presented in a similar grammatical form.
Examples:
- Nouns: “He enjoys reading, writing, and jogging.”
- Verbs: “She likes to hike, to swim, and to camp.”
- Mixed: Incorrect – “He enjoys running, to swim, and biking.” Correct – “He enjoys running, swimming, and biking.”
Identifying Parallel Structure
Recognizing parallel structure involves looking for elements in a sentence meant to be seen as related or of equal importance. These elements should share the same grammatical form to achieve balance and equality.
- Guidelines for Identification:
- Look for lists or series within a sentence. Are the items presented in a consistent grammatical form?
- Check if the compared elements follow the same structure in comparison or contrast.
- Pay attention to conjunctions like “and,” “or,” “but,” “not only…but also,” which often signal the need for parallel structure.
Understanding the foundational aspects of parallel structure sets the stage for its practical use. Through careful attention to grammatical form and the maintenance of consistency across related elements, writers and speakers can harness the power of parallelism to enrich their English communication. This enhances sentences’ aesthetic appeal and clarity, impact, and memorability.

Part 2: Implementing Parallel Structure in Writing
Mastering parallel structure in writing elevates the elegance of your prose and clarifies your ideas, making them more accessible and engaging to your audience. Hereโs how to seamlessly integrate this powerful device into your writing:
In Lists and Series
One of the most common applications of parallel structure is in lists or series, where maintaining grammatical consistency helps to ensure clarity and readability.
- Example: “For her birthday, she asked for a doll, a puzzle, and a book.” (All list items are nouns.)
- Common Mistake: Mixing forms within a list can confuse readers: “For her birthday, she asked for a doll, solving a puzzle, and to read a book.”
In Comparisons and Contrasts
Parallel structure is crucial when comparing or contrasting, as it effectively highlights the similarities or differences between items.
- Example: “Writing is as much about revising as it is about creating.” (Both “revising” and “creating” are gerunds, making the comparison clear and balanced.)
- Improving Clarity: Without parallel structure: “Writing is as much about revising as to create.”

Part 3: Parallel Structure in Speech and Rhetoric
Parallel structure isnโt just a tool for writers; itโs also a potent rhetorical device in speechmaking and everyday conversation, enhancing emphasis, persuasiveness, and memorability.
Enhancing Speeches and Presentations
Using parallel structure in speeches and presentations can make your points more memorable and your arguments more compelling.
- Example: “Ask not what your country can do for you โ ask what you can do for your country.” โJohn F. Kennedy. The parallel structure in Kennedyโs famous line reinforces the reciprocal relationship between citizens and their country.
Rhetorical Devices and Parallelism
Parallel structure underpins many rhetorical devices, such as anaphora (repetition of the same word or phrase at the beginning of successive clauses) and antithesis (juxtaposing contrasting ideas in parallel structures).
- Example of Anaphora: “We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets…” โWinston Churchill.
- Example of Antithesis: “It was the best of times, it was the worst of times…” โCharles Dickens.
These examples underscore how parallel structure can be strategically employed to enhance the effectiveness of verbal communication. It draws in listeners with its rhythm and balance and leaves a lasting impact by reinforcing key ideas.

Part 4: Common Mistakes and How to Avoid Them
While parallel structure can significantly enhance your writing and speaking, misapplication can lead to confusion or awkwardness. Recognizing and avoiding common pitfalls is crucial for effective communication.
Lack of Consistency in Form
One of the most prevalent errors in using parallel structure is a lack of consistency in grammatical form, which can disrupt the flow of a sentence and confuse the reader or listener.
- Strategy for Accuracy: After drafting a sentence, especially one with a list or comparison, review it to ensure that all elements share the same grammatical form. Reading aloud can also help identify inconsistencies that might be overlooked when reading silently.
Overcomplicating Sentence Structure
To achieve parallelism, there’s a risk of creating overly complex or cumbersome sentences, which could potentially obscure the intended message.
- Maintaining Clarity: Strive to balance employing parallel structure and keeping sentences clear and concise. If a sentence becomes too convoluted, consider simplifying it or breaking it into shorter sentences while aiming for parallelism, enhancing clarity and impact.
Conclusion
Parallel structure is a cornerstone of effective English communication, lending clarity, rhythm, and persuasive power to written and spoken language. By aligning grammatical forms within sentences, writers and speakers can create resonant messages that captivate and engage audiences. This guide has traversed the essentials of parallel structure, from its foundational principles to practical applications and common pitfalls to avoid.
Encouragement for Continuous Practice
Mastering parallel structure requires mindfulness in practice and a willingness to revise for clarity and elegance. You can encourage yourself to experiment with this stylistic device in your daily writing and speaking endeavors. As you become more attuned to the nuances of parallel structure, you’ll discover its profound ability to elevate your language, making your expressions more coherent and compelling.
