Unlock Sentence Clarity: Parallel Structure Explained!

Achieving sentence clarity is paramount in effective communication, and parallel structure serves as a critical element. The Purdue OWL, a well-regarded resource for writers, emphasizes the importance of consistency in grammatical form. One key question writers often face is: what is a parallel structure in a sentence? Essentially, it involves using the same pattern of words to show that two or more ideas have the same level of importance. Grammatical correctness, a cornerstone of effective writing, directly benefits from a solid understanding of parallel construction. Even esteemed institutions like the Modern Language Association (MLA) advocate for parallel structure as a means to enhance readability and coherence in academic writing. So, mastering parallel structure is crucial for anyone aiming to write with precision and impact.

In the realm of effective writing, clarity reigns supreme. A well-crafted sentence, like a perfectly balanced scale, delivers its message with precision and grace. When sentences lack this equilibrium, however, they can become convoluted and confusing, obscuring the intended meaning and frustrating the reader.
The Importance of Clarity
Clarity in writing is not merely a stylistic preference; it is a fundamental requirement for effective communication. When your writing is clear, your audience can easily understand your ideas, arguments, and instructions. Ambiguity and convoluted phrasing create barriers, hindering comprehension and potentially leading to misinterpretations.
Unveiling the Confusion
Consider the following sentence:
"She enjoys reading novels, to take long walks, and playing the piano."
Do you stumble slightly while reading it?
The shift in grammatical structure disrupts the flow.
The sentence presents a list of activities, but the items are not presented in a consistent format. "Reading novels" is a gerund phrase, "to take long walks" is an infinitive phrase, and "playing the piano" is another gerund phrase. This inconsistency creates a sense of imbalance, making the sentence awkward and less effective than it could be.
This is because a clear sentence would make use of parallel structure.
Parallel Structure: The Key to Unlocking Clarity
Fortunately, there's a powerful tool to combat such imbalance: parallel structure. This principle, rooted in the very foundations of grammar, dictates that elements within a sentence that serve a similar function should also share a similar grammatical form.
In essence, it's about creating a sense of rhythm and symmetry, allowing your readers to glide effortlessly through your prose.

This article will serve as your comprehensive guide to understanding and implementing parallel structure. Mastering this technique will not only enhance the clarity of your writing but also elevate its overall quality and impact.
In essence, it's about creating a sense of rhythm within your writing, a harmonious flow that allows your reader to glide effortlessly through your ideas. But how is this achieved? The answer lies in understanding the grammatical bedrock upon which clarity is built.
Defining Parallel Structure: A Grammatical Foundation
Parallel structure, at its core, is a principle of grammatical symmetry. It dictates that elements within a sentence which have similar functions should also have similar forms. This applies whether you’re dealing with individual words, phrases, or even entire clauses.
It's the art of arranging words and phrases in a way that mirrors their importance and role within the sentence.
The Essence of Grammatical Symmetry
Think of parallel structure as a reflection in a mirror. On one side, you have a grammatical form; on the other, you have its identical twin. This mirroring effect isn't just for aesthetics; it's about ensuring that your reader's brain can process information efficiently.
When elements are presented in a consistent format, the reader can easily recognize the relationship between them. This minimizes cognitive load and allows them to focus on the content, rather than struggling with the structure.
Orchestrating Words, Phrases, and Clauses
Parallel structure comes into play whenever you are listing items, connecting ideas with conjunctions, or using correlative conjunctions to link related elements.
Whether it's a simple list of nouns, a series of verb phrases, or a string of complex clauses, the principle remains the same: maintain consistency.
For instance, instead of writing, "She likes hiking, to swim, and biking," you would write, "She likes hiking, swimming, and biking," or "She likes to hike, to swim, and to bike". Each item in the list is now in the same grammatical form (gerund or infinitive).
The Indispensable Role of Syntax
Syntax, the arrangement of words and phrases to create well-formed sentences, is the architect behind parallel structure. A firm grasp of syntax is essential to identifying and creating parallel constructions.
It's not enough to simply string together similar words; you must also ensure that the grammatical structure of each element aligns with the others.
This requires careful attention to detail and a deep understanding of how different parts of speech function within a sentence. Without a solid understanding of syntax, your attempts at parallelism may fall flat, resulting in awkward or even nonsensical constructions.
Visualizing Parallelism: A Simple Formula
To further illustrate the concept, consider these basic formulas:
-
A, B, and C: This represents a simple list where A, B, and C are elements of the same grammatical type (e.g., nouns, verbs, adjectives).
-
X is to Y as A is to B: This formula demonstrates parallelism in comparisons, where the relationship between X and Y mirrors the relationship between A and B.
These visual representations underscore the importance of maintaining a balanced and symmetrical structure within your sentences.
The mirroring effect isn't just for aesthetics; it's about ensuring that your reader's brain can process information efficiently.
When elements are presented in a consistent format, the reader can easily recognize the relationship between them. This minimizes cognitive load and allows them to focus on the content, rather than struggling with the structure.
With the core principle of grammatical symmetry now established, it's time to explore how this principle manifests in practical writing. Parallelism isn't a one-size-fits-all solution, but rather a versatile tool that can be applied to various elements within a sentence to enhance clarity and flow.
The Building Blocks: Elements That Must Align
Parallel structure finds its greatest utility in aligning various sentence elements, each contributing uniquely to the overall harmony of the writing. Lists, conjunctions, and correlative conjunctions, in particular, stand to benefit significantly from the careful application of parallelism. The goal is to create a seamless reading experience, where each element complements the others in both meaning and form.
Parallelism in Lists: Creating Order and Clarity
Lists are ubiquitous in writing, serving to enumerate items, ideas, or actions. When constructing a list, each item should adhere to a consistent grammatical structure. This not only enhances readability but also emphasizes the equal importance of each element within the list.
Consider the following example:
- Incorrect: "My duties include writing reports, attending meetings, and employee training."
- Correct: "My duties include writing reports, attending meetings, and training employees."
In the corrected version, all elements are gerunds (verb forms ending in "-ing"), creating a parallel structure that is both grammatically sound and aesthetically pleasing. This simple adjustment transforms the list from a jumbled collection of ideas into a cohesive and easily digestible unit.
The Role of Simple Conjunctions: And, But, Or
Simple conjunctions like "and," "but," and "or" are used to connect words, phrases, or clauses. To maintain parallelism, the elements being joined by these conjunctions should be of the same grammatical form.
For example:
- Incorrect: "She likes to read novels and watching movies."
- Correct: "She likes reading novels and watching movies."
By ensuring that both elements connected by "and" are gerunds, the sentence achieves parallelism, making it clearer and more concise. Simple conjunctions are fundamental to sentence construction, and using them correctly can significantly improve the overall quality of your writing.
Correlative Conjunctions: A Partnership in Parallelism
Correlative conjunctions (e.g., both/and, either/or, neither/nor, not only/but also) work in pairs to connect related elements within a sentence. The key to using these conjunctions effectively is to ensure that the grammatical structure following each conjunction is identical.
Consider the following:
- Incorrect: "You can either call me or send an email."
- Correct: "You can either call me or email me."
Here, the corrected sentence maintains parallelism by ensuring that the same verb form (call, email) follows each part of the correlative conjunction "either/or". This creates a balanced structure that is easy for the reader to follow.
Examples of Correct Parallelism: A Grammatical Showcase
To further illustrate the principles of parallel structure, let's examine several examples that showcase its application across different grammatical elements:
Nouns
- "The conference focused on strategy, innovation, and leadership." (All elements are nouns.)
Verbs
- "He likes to swim, hike, and climb." (All elements are base forms of verbs.)
Phrases
- "The cake was decorated with frosting, sprinkles, and a cherry on top." (All elements are prepositional phrases.)
Clauses
- "The report showed that sales increased, that costs decreased, and that profits soared." (All elements are subordinate clauses.)
By adhering to these principles, you can ensure that your writing is not only grammatically correct but also clear, concise, and impactful. Parallel structure is more than just a stylistic choice; it's a fundamental tool for effective communication.
The goal is to create a seamless reading experience, where each element complements the others in both meaning and form.
Spotting the Flaws: Identifying Faulty Parallelism
While understanding the rules of parallelism is crucial, recognizing when these rules are broken is equally important. Faulty parallelism, or a lack of parallel structure, can significantly hinder the clarity and flow of your writing, creating confusion and weakening your message.
Let's explore how to identify these structural missteps and understand their impact.
What is Faulty Parallelism?
Faulty parallelism occurs when elements within a sentence that are intended to be parallel are not grammatically consistent. This inconsistency disrupts the rhythm and clarity of the sentence, forcing the reader to pause and re-evaluate the meaning.
It's like hitting a wrong note in a melody, jarring the listener and disrupting the harmony.
Examples of Faulty Parallelism
Let's examine some examples to illustrate how faulty parallelism manifests in writing:
- Incorrect: "She enjoys reading, hiking, and to swim."
- Correct: "She enjoys reading, hiking, and swimming."
In the incorrect example, "to swim" breaks the parallel structure established by the gerunds "reading" and "hiking." The corrected sentence uses "swimming" to maintain consistency.
Here’s another example focusing on different parts of speech:
- Incorrect: "The company values innovation, integrity, and being customer-focused."
- Correct: "The company values innovation, integrity, and customer focus."
The faulty sentence mixes nouns ("innovation," "integrity") with a gerund phrase ("being customer-focused"). Correcting it involves using consistent nouns throughout.
Identifying Faulty Parallelism: A Checklist
Identifying faulty parallelism requires a keen eye for detail and an understanding of grammatical consistency. Here’s a checklist to guide you:
- Check for Lists: Examine any lists within your sentences. Ensure that each item in the list is expressed using the same grammatical form (e.g., all nouns, all verbs, all phrases).
- Analyze Conjunctions: Pay close attention to elements connected by conjunctions (and, but, or). These elements should be grammatically similar.
- Scrutinize Correlative Conjunctions: When using correlative conjunctions (both/and, either/or, neither/nor, not only/but also), ensure that the structure following each part of the conjunction is parallel.
- Read Aloud: Sometimes, reading the sentence aloud can help you identify awkward phrasing or inconsistencies that you might miss when reading silently.
By systematically checking for these potential problem areas, you can significantly reduce the occurrence of faulty parallelism in your writing.
The Awkwardness Factor
Beyond clarity, faulty parallelism often leads to writing that simply sounds awkward. Even if a reader can technically understand the meaning of the sentence, the jarring structure can create a negative impression.
Awkward phrasing can undermine your credibility and detract from the overall impact of your message. By striving for parallel structure, you not only enhance clarity but also improve the aesthetic appeal of your writing.
Spotting errors is only half the battle; knowing how to correct them is where the real power lies. Transforming a clumsy, awkward sentence into a polished, clear statement significantly enhances your writing. It ensures your message is not only understood but also appreciated for its precision and flow.
Fixing the Imbalance: Correcting Faulty Parallelism
Correcting faulty parallelism isn't just about grammar; it's about refining your message to achieve maximum impact. The goal is to create sentences that not only sound better but also communicate your ideas with greater clarity and precision. Let's break down the process.
Step 1: Identify the Non-Parallel Element
The first step is to pinpoint the element that disrupts the parallel structure. Ask yourself: What part of this sentence doesn't fit with the others? Look for inconsistencies in grammatical form, verb tense, or phrasing.
Often, the non-parallel element will stand out because it feels awkward or interrupts the flow of the sentence. This requires a keen eye and a willingness to dissect your sentences critically.
Step 2: Choose a Consistent Grammatical Structure
Once you've identified the culprit, determine the grammatical structure that should be used for all parallel elements. This might involve using all nouns, all verbs in the same tense, or all phrases with a similar structure.
The key is consistency. Select a pattern and stick to it throughout the sentence.
Step 3: Revise to Achieve Parallelism
Now, rewrite the sentence, ensuring that all parallel elements conform to the chosen grammatical structure. This may involve changing the wording, adding or removing words, or reordering the sentence.
Pay close attention to detail, ensuring that each element is grammatically and logically consistent with the others. This is where your understanding of grammar truly shines.
Step 4: Compare Before and After
The most effective way to appreciate the improvement is to compare the original, faulty sentence with the corrected version. This side-by-side comparison highlights the difference in clarity and flow.
Examples of Corrected Faulty Parallelism
Let's illustrate this process with a few examples:
Example 1: Inconsistent Verb Forms
- Before: "He likes to read books, playing sports, and watching movies."
- After: "He likes reading books, playing sports, and watching movies."
In this example, the original sentence mixes an infinitive phrase ("to read books") with gerunds ("playing sports," "watching movies"). The corrected sentence uses gerunds for all three elements, creating a consistent and parallel structure.
Example 2: Mixing Nouns and Phrases
- Before: "The project requires dedication, skill, and to be on time."
- After: "The project requires dedication, skill, and punctuality."
Here, the original sentence combines nouns ("dedication," "skill") with an infinitive phrase ("to be on time"). The revised sentence uses nouns consistently, resulting in a more balanced and professional tone.
Example 3: Non-Parallel Clauses
- Before: "She is known for her intelligence, her kindness, and that she is always on time."
- After: "She is known for her intelligence, her kindness, and her punctuality."
In this case, the faulty sentence awkwardly uses a noun phrase and two nouns.
Example 4: With Correlative Conjunctions
- Before: "You should either study hard or failing the exam."
- After: "You should either study hard or fail the exam."
Correlative conjunctions like "either/or" require the elements they connect to be parallel. The corrected sentence ensures that both options presented are in the same verb form.
By carefully analyzing and revising sentences, you can eliminate faulty parallelism and significantly improve the clarity and impact of your writing.
Fixing the imbalance often involves more than just swapping a few words. It's about consciously reshaping the sentence to reflect a balanced and harmonious structure. With practice, you'll develop an intuition for spotting and correcting faulty parallelism.
Applying Parallel Structure: Practical Tips and Techniques
Achieving consistent parallelism isn't a matter of luck; it's a skill honed through conscious application and refinement. By integrating specific strategies into your writing process, you can cultivate a natural ability to construct balanced and effective sentences.
The Power of Precise Word Choice
The foundation of parallel structure lies in the selection of appropriate and consistent words. Choosing words that share a similar grammatical function is crucial for maintaining balance within your sentences.
For instance, if you're listing activities, ensure all items are either gerunds (verbs ending in "-ing") or infinitives ("to" + verb). Mixing these forms will disrupt the parallelism and create an awkward reading experience.
Careful word choice also extends to maintaining consistent tone and style. Ensure that the words you select are appropriate for your intended audience and purpose.
A formal report, for example, will require different vocabulary choices than a casual blog post.
Parallelism in Revision and Editing
The revision and editing stages offer valuable opportunities to refine your writing and ensure that all sentences adhere to the principles of parallel structure.
Take a step back from your writing and critically examine each sentence, paying close attention to lists, conjunctions, and correlative conjunctions.
Identify any instances of faulty parallelism and consciously restructure the sentences to achieve balance. Consider printing out your document and reviewing it with a pen in hand to catch errors that you might otherwise miss on a screen.
Reading your work aloud can also help you identify awkward phrasing and inconsistencies in sentence structure.
Actionable Steps for Parallelism
Here are some specific techniques you can integrate into your writing routine to strengthen your use of parallel structure:
-
Read Your Writing Aloud: As mentioned earlier, reading your work aloud helps you hear inconsistencies and awkward phrasing that might be missed when reading silently. Pay attention to the rhythm and flow of your sentences.
-
Utilize Grammar Tools: Grammar-checking software can be a valuable asset in identifying potential instances of faulty parallelism. However, remember that these tools are not foolproof, and it's essential to exercise your own judgment.
-
Create a Checklist: Develop a checklist of common parallelism errors to look for during the editing process. This will help you stay focused and ensure that you're addressing all potential issues.
-
Practice Regularly: The more you practice identifying and correcting faulty parallelism, the more natural it will become. Make a conscious effort to apply these principles in all of your writing, from emails to formal reports.
By consistently applying these tips and techniques, you'll develop a keen eye for parallel structure and elevate the clarity and effectiveness of your writing.
Faulty parallelism can make even the most insightful ideas seem muddled and unprofessional. Thankfully, with targeted strategies, we can reshape our sentences into reflections of balanced and effective communication. This leads us to an important question: Why bother mastering parallelism in the first place? What tangible benefits does it offer beyond mere grammatical correctness?

Frequently Asked Questions: Parallel Structure
Here are some common questions about parallel structure and how to use it effectively to improve your writing.
Why is parallel structure important?
Parallel structure enhances clarity and readability. It helps the reader quickly grasp the relationship between elements in a list or comparison, making your writing more concise and impactful. Using parallel structure in sentences also demonstrates a better grasp of grammar.
What is a parallel structure in a sentence, exactly?
A parallel structure in a sentence means using the same grammatical form for elements that are similar in meaning or function. This could be nouns, verbs, phrases, or clauses. The key is to ensure each element has the same grammatical pattern.
What are some common errors to avoid when using parallel structure?
Mixing grammatical forms is a frequent mistake. For example, avoid mixing gerunds (verbs ending in -ing used as nouns) with infinitives (to + verb) in a list. Another common error is neglecting to repeat prepositions or articles where needed for parallelism.
How can I check if my sentence has parallel structure?
Read the sentence aloud slowly and pay attention to the rhythm and flow. Do the listed elements sound awkward or jarring? Try diagramming the sentence or identifying the core grammatical structure of each element. If they aren't the same, revise for parallelism.
