Definition of Parallel Structure

Parallel structure is the repetition of a chosen grammatical form within a sentence. By making each compared item or idea in your sentence follow the same grammatical pattern, you create a balanced and rhythmic flow that enhances readability and comprehension. Parallelism can involve single words, phrases, or entire clauses. The key is maintaining consistency in grammatical form when presenting related ideas.

The function of parallel structure is to create a sense of balance and equality between the elements being compared or listed. It signals to the reader that these elements are of equal importance and should be understood in a similar way.

Using parallel structure can also make your writing more persuasive and memorable, as it creates a sense of rhythm and emphasis.

Parallel structure is used extensively in various contexts, from everyday conversation to formal writing. It is particularly important in persuasive writing, where it can be used to emphasize key points and create a sense of conviction.

In literature, parallelism is often used to create poetic effects and enhance the emotional impact of the text. In professional settings, parallel structure is crucial for writing clear and concise reports, proposals, and presentations.

Structural Breakdown

The basic structure of parallel construction involves coordinating words, phrases, or clauses using coordinating conjunctions (such as and, but, or, nor, yet, so, and for) or correlative conjunctions (such as both…and, either…or, neither…nor, not only…but also, and whether…or). The elements being coordinated must have the same grammatical form.

Here’s a breakdown of the key components:

  • Words: Coordinating nouns with nouns, verbs with verbs, adjectives with adjectives, etc.
  • Phrases: Coordinating prepositional phrases, infinitive phrases, gerund phrases, etc.
  • Clauses: Coordinating independent clauses or dependent clauses.

Consistency is key. If you start with a verb, you must continue with verbs.

If you begin with a prepositional phrase, all subsequent elements should also be prepositional phrases. This uniformity creates the desired balance and clarity.

For example, consider the following sentence:

Incorrect: She likes singing, to dance, and playing the piano.

Correct: She likes singing, dancing, and playing the piano. (All gerunds)

Correct: She likes to sing, to dance, and to play the piano. (All infinitives)

In the incorrect sentence, the grammatical forms are inconsistent (gerund, infinitive, gerund phrase), disrupting the flow and clarity. The corrected sentences demonstrate how maintaining a consistent grammatical form (all gerunds or all infinitives) creates parallel structure.

Types of Parallel Structure

Parallel structure manifests in various forms, each serving to enhance clarity and rhythm in different contexts. Understanding these types will enable you to effectively apply parallelism in your writing.

Parallel Words

Parallel words involve coordinating single words of the same grammatical type. This is the simplest form of parallelism, but it is crucial for creating balanced and effective sentences.

Example:

She is intelligent, beautiful, and kind. (All adjectives)

Parallel Phrases

Parallel phrases involve coordinating phrases of the same type, such as prepositional phrases, infinitive phrases, or gerund phrases. This type of parallelism adds complexity and depth to your writing.

Example:

He enjoys reading books, watching movies, and listening to music. (All gerund phrases)

Parallel Clauses

Parallel clauses involve coordinating clauses of the same type, such as independent clauses or dependent clauses. This type of parallelism is often used to create complex and nuanced sentences.

Example:

The dog barked, the cat meowed, and the bird sang. (All independent clauses)

Parallel Lists

Parallel lists involve presenting a series of items in a consistent grammatical form. This is particularly important in bullet points, numbered lists, and other types of enumerated content.

Example:

The project requires:

  • Planning the strategy.
  • Executing the plan.
  • Monitoring the results.

Usage Rules of Parallel Structure

Several rules govern the proper use of parallel structure. Adhering to these rules ensures clarity and enhances the effectiveness of your writing.

  1. Use the Same Grammatical Form: Ensure that all elements in a series or comparison have the same grammatical structure. This means using nouns with nouns, verbs with verbs, phrases with phrases, and clauses with clauses.
  2. Use Coordinating Conjunctions Correctly: When using coordinating conjunctions (and, but, or, nor, yet, so, for), make sure the elements on either side of the conjunction are parallel.
  3. Use Correlative Conjunctions in Pairs: Correlative conjunctions (both…and, either…or, neither…nor, not only…but also) must be used in pairs, and the elements following each part of the pair must be parallel.
  4. Maintain Consistency in Lists: In lists, bullet points, or numbered items, ensure that each item follows the same grammatical pattern.
  5. Avoid Mixing Active and Passive Voice: When comparing actions, maintain consistency in voice (active or passive).

There are few exceptions to these rules. In some cases, slight variations in grammatical form may be acceptable if they do not compromise clarity.

However, it is generally best to adhere strictly to the rules of parallel structure to avoid ambiguity.
