Introduction: Parallel Structure in Sentences : The Key to Polished Prose

Have you ever read a sentence that felt clunky or unbalanced? The issue might be a lack of parallel structure in sentences. Also known as parallelism, this fundamental grammatical principle is the secret ingredient that brings rhythm, clarity, and persuasive power to your writing. It ensures that similar ideas are expressed using similar grammatical forms, creating a sense of order and professionalism. Whether you’re crafting an essay, a business report, or answering a competitive exam, understanding parallel structure in sentences is non-negotiable for effective communication.

Understanding Parallel Structure in Sentences

Parallel structure means using the same pattern of words (grammatical form) to show that two or more ideas have the same level of importance. This can happen at the word, phrase, or clause level. The core rule is: items in a list, series, or pair must be grammatically equal.

Important Tips for Students & Exam Candidates:

  1. Spot the Conjunctions: Watch for words like and, or, but (yet), and correlative conjunctions like not only/but also, either/or, neither/nor, both/and. These are prime spots where parallelism is required.
  2. The “List” Test: In any list or series, ensure every item is the same part of speech (all nouns, all gerunds, all infinitive verbs, all clauses).
  3. Comparisons with “Than” or “As”: When making comparisons, the elements being compared must be parallel (e.g., “Her speech was more inspiring than confusing” – both are adjectives).
  4. After a Colon: When a colon introduces a list or explanation, the following elements should be parallel.
  5. For Résumés & Essays: Use parallel structure in bullet points and thesis statements. It projects competence and organization (e.g., “Duties: Trained staff, managed inventory, developed schedules” – all past tense verbs).

FAQs on Parallel Structure in Sentences

Q1: Is parallel structure only important for lists?
No. While crucial for lists and series, parallelism is essential with correlative conjunctions (not only/but also), comparisons (than, as), and elements linked by coordinating conjunctions (and, or, but) to ensure grammatical balance.

Q2: Can I start a parallel series with “to” and then switch to “-ing” verbs?
No. This breaks parallelism. Choose one form and stick to it. Incorrect: “She likes to run, swimming, and to cycle.” Correct: “She likes to run, to swim, and to cycle.” OR “She likes running, swimming, and cycling.”

Q3: How does parallel structure help in competitive exams?
Exams like the SAT, GRE, GMAT, and civil services often have direct “error identification” or “sentence correction” questions testing parallelism. Using it correctly in essay sections also improves your writing score by demonstrating command over syntax and clarity.

Conclusion: Harness the Power of Parallelism

Mastering parallel structure in sentences is not merely about obeying a grammar rule—it’s about elevating your writing from confusing to clear, from amateurish to authoritative. By consistently applying this principle, you create text that is easier to read, more persuasive, and more memorable. Make a conscious effort to check for parallel structure in sentences during your editing process; this simple habit will significantly sharpen all your written communication, giving you an undeniable edge in academic and professional arenas.
