Which Sentence Uses Correct Parallel Structure

Mastering Parallel Structure: Which Sentence Sings in Harmony?

Parallel structure, also known as parallelism, is a fundamental principle of grammar that enhances clarity, readability, and the overall effectiveness of your writing. It involves using the same grammatical structure for similar items in a series or list. Understanding and applying parallel structure correctly transforms your sentences from clunky and confusing to elegant and impactful. This article will delve into the intricacies of parallel structure, providing clear explanations, examples, and exercises to help you master this crucial aspect of effective writing. We will explore various scenarios where parallel structure is essential, highlight common mistakes, and equip you with the skills to identify and correct them. By the end, you’ll be able to confidently determine which sentences use correct parallel structure and craft your own grammatically sound and stylistically polished sentences.

Understanding the Basics of Parallel Structure

Parallel structure ensures that elements of equal grammatical importance are presented consistently. This consistency applies to various grammatical forms, including:

Nouns: Running, jumping, and swimming are all great exercises. (All are gerunds)
Verbs: She likes to sing, to dance, and to act. (All are infinitive phrases)
Adjectives: The house is large, spacious, and comfortable. (All are adjectives)
Adverbs: He spoke clearly, confidently, and persuasively. (All are adverbs)
Prepositional Phrases: The book is on the table, under the chair, and in the drawer. (All are prepositional phrases)
Clauses: Although she was tired, although she was hungry, and although she was frustrated, she continued working. (All are subordinate clauses)

The key is to maintain consistency. If you start a list with a gerund (a verb acting as a noun), all subsequent items in that list must also be gerunds. Similarly, if you begin with an infinitive phrase, the rest should follow suit. Inconsistent grammatical structures disrupt the flow and clarity of your writing, making it difficult for the reader to understand your message.

Identifying Incorrect Parallel Structure

Let’s look at some examples to illustrate how incorrect parallel structure can muddle your meaning:

Incorrect: I enjoy reading books, watching movies, and to listen to music.

Correct: I enjoy reading books, watching movies, and listening to music. (All are gerunds)

Incorrect: She is intelligent, hardworking, and has a positive attitude.

Correct: She is intelligent, hardworking, and positive. (All are adjectives) or She is intelligent, hardworking, and has a positive attitude. (This is correct but less concise)

Incorrect: He is kind, generous, and he helps others.

Correct: He is kind, generous, and helpful. (All are adjectives) or He is kind, generous, and he helps others. (This is correct but less concise)

Notice how the incorrect examples mix different grammatical forms within the same series. The corrected versions maintain consistency, resulting in clearer and more effective sentences.

Common Mistakes to Avoid

Several common pitfalls lead to errors in parallel structure. Let’s examine some of them:

Mixing verb tenses: Avoid shifting between past, present, and future tenses within a parallel structure. For instance: "He walked to the store, bought groceries, and will return home." To correct this, maintain consistency: "He walked to the store, bought groceries, and returned home."
Using different types of phrases or clauses: As seen in the previous examples, combining different types of phrases (infinitive phrases, gerunds, prepositional phrases, etc.) disrupts parallelism. Ensure all items in the list have the same grammatical structure.
Ignoring correlative conjunctions: Correlative conjunctions, such as not only...but also, either...or, neither...nor, require parallel structure. The elements connected by these conjunctions must have the same grammatical form. For instance: "She is not only intelligent but also she is hardworking" is incorrect. The correct version is: "She is not only intelligent but also hardworking."
Mismatched comparisons: When making comparisons using words like than or as, ensure the compared elements are grammatically parallel. For example: "He is taller than his brother is tall" is incorrect. The correct version is: "He is taller than his brother."

Advanced Parallel Structure: Complex Sentences

Parallel structure becomes more challenging with complex sentences but remains crucial for clear communication. Consider these scenarios:

Parallel Compound Predicates: These are sentences with multiple verbs sharing the same subject. Ensure all verbs have the same tense and form. Incorrect: "She sang a song and played the piano." This mixes past tense and past participle; more appropriate: "She sang a song and played the piano."

Parallel Modifiers: When using multiple modifiers to describe the same noun, ensure they all have the same grammatical form. Incorrect: "The red, shiny, and very fast car sped away." While mostly correct, this slightly better: "The red, shiny, and fast car sped away."

Parallel Lists Within Sentences: Sometimes, you might have parallel structures nested within larger sentences. This requires careful attention to maintain consistency throughout the sentence. Incorrect: "The meeting was intended to discuss the budget, to address the recent complaints from employees, and we also needed to finalize the sales plan." This can be improved through sentence restructuring: "The meeting was intended to discuss the budget, address the recent employee complaints, and finalize the sales plan."

Practical Exercises to Strengthen Your Skills

Here are some exercises to test your understanding of parallel structure:

Identify the sentences with incorrect parallel structure and rewrite them correctly:

a. He enjoys swimming, hiking, and to play video games. b. She is kind, compassionate, and always helping others. c. The cake is delicious, moist, and it looks beautiful. d. Not only is he intelligent, but also he is incredibly creative. e. The movie was long, boring, and the acting was poor.
Rewrite the following sentences to incorporate correct parallel structure:

a. My goals are to get a promotion, to save money, and want to travel. b. The team is composed of talented, creative, and who can work under pressure. c. She is not only a talented musician but also a gifted artist. d. He is smarter than his brother is smart.

Frequently Asked Questions (FAQ)

A: While not always strictly required, parallel structure significantly enhances the clarity and elegance of your writing. It's particularly important in lists, comparisons, and compound sentences.

Q: What happens if I don't use parallel structure?

A: Your writing might become confusing, less readable, and less impactful. The reader may struggle to understand your intended meaning due to the lack of consistent grammatical structure.

Q: How can I improve my ability to identify and correct parallel structure errors?

A: Practice is key. Regularly review your own writing and the writing of others, actively looking for instances of parallel structure. Use online grammar checkers, but always double-check their suggestions; they can sometimes be inaccurate.

Q: Is there a specific rule about the length of parallel elements?

A: The length of parallel elements is not strictly regulated, but it's beneficial to keep them relatively consistent in length for improved readability. Extremely long and short parallel elements can create a sense of imbalance.
