Whether you are writing a casual email, a business report, or an academic essay, using parallel structure—also known as parallelism—prevents your sentences from sounding awkward or disjointed.

This guide covers everything you need to know about parallelism, including the core rules, step-by-step explanations, and an extensive list of examples for every situation.

What is Parallel Structure? (Definition & Rule)

Parallel structure is the repetition of a specific grammatical form within a sentence. When you write a list, compare items, or use coordinating conjunctions (like and, but, or), the items connected must follow the same grammatical pattern.

If you start a list with an “-ing” verb (gerund), all other verbs in that list must also be “-ing” verbs. If you mix verb forms, noun phrases, or clause types, you create “faulty parallelism.”

The Golden Rule: Match nouns with nouns, verbs with verbs, adjectives with adjectives, and clauses with clauses.

Step-by-Step Explanation of Parallel Structure

To use parallel structure correctly, follow these four steps:

Identify the items in a series or comparison: Look for conjunctions like and, or, but, yet, or comparative words like than and as.
Check the grammatical form of the first item: Is it a noun? An infinitive verb (to + verb)? A gerund (verb + ing)? A prepositional phrase?
Check the remaining items: Do they match the exact form of the first item?
Revise if necessary: Change the mismatched items so that they share the exact same grammatical structure.

3 Easy Tips to Remember Parallel Structure

The Conjunction Test: Whenever you use and, but, or or, look at the word immediately before and after it. They must be the same part of speech.
The List Test: If you create a bulleted list, make sure every bullet point starts with the same type of word (e.g., all action verbs or all nouns).
The Voice Test: Read the sentence out loud. Faulty parallelism often ruins the rhythm of a sentence, making it sound clunky or awkward to the ear.

5 FAQs About Parallel Structure

1. What is an example of parallel structure?

A simple example is: “I like running, swimming, and hiking.” All three activities end in “-ing,” making the sentence grammatically parallel.

2. Why is parallel structure important?

It improves readability, creates a smooth rhythm in writing, and prevents grammatical confusion. It shows that two or more ideas have the same level of importance.

3. How do you identify faulty parallelism?

Look for lists or comparisons joined by coordinating conjunctions (and, or, but). Check if the items in the list belong to the same grammatical category (e.g., all nouns, all verbs). If they don’t, it is faulty parallelism.

4. Can parallel structure be used in bullet points?

Yes. In fact, bullet points must use parallel structure. If the first bullet starts with an action verb (e.g., “Manage team”), all subsequent bullets should also start with action verbs (e.g., “Analyze data,” “Draft reports”).

5. Does parallel structure apply to verb tenses?

Yes. If you are listing actions that happened in the past, all verbs in the series should be in the past tense (e.g., “She arrived, sat down, and opened her laptop”).
