Words That Are Parallel To The Bold Words

Words That Are Parallel to the Bold Words

You've seen those sentences that just sound* right. The ones where the grammar clicks into place like puzzle pieces. And then there are the ones that feel off, even if you can't quite put your finger on why. A lot of that comes down to parallelism — matching grammatical structures so your words work together instead of fighting each other.

But here's the thing about parallelism: it's not just about sounding good. It's about clarity. When your sentence structures line up, readers don't have to do extra mental work to follow what you're saying. They can focus on your message instead of stumbling over mismatched grammar.

What Is Parallelism in Writing?

Parallelism is the practice of using the same grammatical structure for similar elements within a sentence or across sentences. Think of it as keeping your words in formation — when one item is a verb, they all should be verbs. When one is a noun phrase, they all should be noun phrases.

It shows up everywhere once you start looking for it. In lists, in comparisons, in compound sentences, even in the way you phrase your headings. The goal isn't to make everything identical, but to make related elements structurally consistent.

The Grammar Behind It

At its core, parallelism is about matching parts of speech. Practically speaking, if you're listing actions, keep them all in the same verb form. If you're describing qualities, keep them all in the same adjective or noun form. This creates a rhythm that readers can follow effortlessly.

Consider the difference between these two sentences:

She likes running, swimming, and to cycle.

She likes running, swimming, and cycling.

The second version flows because all three activities are in the same gerund form. The first one stumbles because "to cycle" breaks the pattern.

Why Parallelism Matters More Than You Think

Most people think parallelism is just a style preference — something that makes writing sound polished but doesn't really change the meaning. This leads to that's not entirely true. Inconsistent parallelism can actually obscure your meaning or make your writing harder to process.

When readers encounter mismatched structures, their brains have to work a little harder to parse what you're saying. In practice, instead of focusing on your content, they're subconsciously correcting your grammar. That's cognitive load you don't want to impose on your audience.

What Goes Wrong Without It

I've seen this play out countless times in business writing. A manager writes:

Our goals are to increase sales, improving customer satisfaction, and reducing costs.

The mixed verb forms make it feel scattered, even though the intent is clear. A quick fix — "to increase sales, improve customer satisfaction, and reduce costs" — instantly makes the sentence feel more authoritative and cohesive.

The same principle applies to longer documents. When your headings, bullet points, and sentence structures maintain parallel forms, your entire piece feels more professional and easier to follow.

How to Spot and Fix Parallel Structure Issues

The good news? Once you know what to look for, parallelism problems become easy to catch. Here's how to identify them in your own writing.

Read Your Lists Aloud

There's something about hearing the rhythm of your words that makes structural mismatches obvious. If you're listing items and the cadence stumbles or feels uneven, you probably have a parallelism issue.

Try this with a sentence like:

The job requires strong communication skills, attention to detail, and to be organized.

Reading it aloud reveals the awkward shift from noun phrases to infinitive. The fix is simple: "to communicate effectively, pay attention to detail, and stay organized" — or "strong communication skills, attention to detail, and organizational skills."

Check Your Comparisons

Parallel structure is especially important in comparisons. When you're saying one thing is like another, the elements you're comparing need to match grammatically.

Compare these:

Managing a team is more challenging than being a solo contributor.

Managing a team is more challenging than working alone.

Both work, but the second is cleaner because "managing" and "working" are both gerunds. The first version mixes a gerund with a prepositional phrase, which creates a subtle mismatch.

Examine Your Headings

Your section headings should follow parallel structure too. If one heading starts with a verb, they all should. If one is a noun phrase, they all should be.

Inconsistent headings create a disjointed reading experience. I've seen articles where some headings are questions ("How Do I Choose?"), others are statements ("Choosing the Right Tool"), and others are commands ("Pick the Best Option"). Pick one approach and stick with it throughout.

Common Mistakes That Break Parallelism

Even experienced writers slip up on parallelism. Here are the most frequent offenders.

Mixing Verb Forms in Lists

This is probably the most common mistake. Writers start a list with one verb form and then switch midway through.

The mix of infinitive ("to analyze"), infinitive phrase ("how to present"), and gerund ("writing") breaks the flow. Better options:

Or:

The training program will teach you analyzing data, presenting findings, and writing reports.

Breaking Parallel Structure in Correlative Pairs

Words like not only...but also*, either...or*, and neither...nor* require parallel structure between the elements they connect.

She not only manages the project but also improving team morale.

The mismatch between "manages" (verb) and "improving" (gerund) breaks the parallel. Fix it:

She not only manages the project but also improves team morale.

Inconsistent Item Formatting in Bullet Points

Bullet points should all follow the same grammatical pattern. If some start with verbs and others with nouns, your list looks sloppy and is harder to scan.

• Increase your daily steps
• Sleep for seven to nine hours
• Eating a balanced diet

The third item breaks the pattern. Either make them all verbs or all nouns:

• Increase your daily steps
• Sleep for seven to nine hours
• Eat a balanced diet

Or:

• Increasing your daily steps
• Sleeping for seven to nine hours
• Eating a balanced diet

Practical Tips for Better Parallelism

Here are the techniques that actually work when you're trying to improve parallel structure in your writing.

Start Sentences with the Same Grammatical Element

When you're writing a series of related sentences, beginning each with the same part of speech creates a satisfying rhythm.

The new policy affects hiring practices. It changes how we evaluate candidates. It impacts our onboarding process.

All three sentences start with "It" + verb, creating natural parallelism.

Use Parallel Structure in Transitions

Transitional phrases work better when they're grammatically consistent. If you're using a series of transitions, keep them in the same form.

First, consider the timeline. Next, evaluate the budget. Finally, assess the risks.

All three transitions are adverbs modifying implied verbs, maintaining parallel structure.

Apply Parallelism to Your Outlines

Before you write, structure your outline with parallel headings. Day to day, if your main points are all action verbs, keep them that way. If they're all noun phrases, maintain that pattern.

This makes your writing more organized from the start and saves you from having to restructure later.

Trust Your Ear

Your ear is often the best tool for catching parallelism issues. If a sentence sounds off when you read it aloud, there's usually a structural mismatch somewhere. Don't dismiss that feeling — investigate it.

FAQ

Does parallelism apply to numbers and data?

Yes. When presenting statistics, keep the format consistent. If you're comparing percentages, present them all as percentages. If you're listing dollar amounts, don't mix exact figures with rounded numbers without explanation.

Can parallelism be overused?

Absolutely. Forced parallelism can make writing sound robotic or unnatural. That's why the goal is clarity and flow, not rigid adherence to rules. If maintaining parallel structure makes your sentence awkward, it's okay to break the pattern.

How do I know if my parallelism is correct?

Read your sentence aloud and listen for stumbles. You can also test by substituting synonyms — if the structure feels different with different words, you likely have a parallelism issue.

Should I worry about parallelism in casual writing?

Even in informal contexts, good parallel

ism improves readability. While you don't need to obsess over every comma in a text message, using consistent structures in emails and professional chats helps convey your message more clearly and prevents your ideas from getting lost in a cluttered sentence.

Conclusion

Parallelism is more than just a technical rule of grammar; it is a fundamental tool for clarity and rhythm. By ensuring that your lists, transitions, and sentence beginnings follow a consistent pattern, you reduce the cognitive load on your reader. This allows them to focus on what* you are saying rather than struggling to manage how you are saying it.

Mastering this skill takes practice, but by using these techniques—starting sentences consistently, aligning your transitions, and trusting your ear—you will transform your writing from a disjointed collection of thoughts into a cohesive, professional, and persuasive force.
