Syntax: Parallel Structure and Sentence Combining in Eighth Grade English
Syntax is the deliberate arrangement of words, phrases, and clauses to create clear, balanced, and rhetorically compelling sentences.
The Principle of Parallel Structure
Parallelism, or parallel structure, is one of the most powerful stylistic tools in English rhetoric. The law of parallel structure dictates that when two or more elements in a sentence share the same grammatical function, they must share the exact same grammatical form. If you are coordinating a list of items, linking elements with correlative conjunctions, or making a direct comparison, you cannot mix infinitives with gerunds, single adjectives with prepositional phrases, or active verbs with passive clauses. Parallelism establishes balance, rhythm, and structural symmetry, making complex ideas effortless for readers to absorb.
+--------------------------------------------------------------------------+
| PARALLEL STRUCTURE ESSENTIALS |
| |
| NON-PARALLEL (Clumsy & Asymmetrical): |
| "The astronaut learned [to navigate], [zero-gravity spacewalking], |
| and [how to repair damaged solar arrays]." |
| |
| PARALLEL (Harmonious & Symmetrical): |
| "The astronaut learned [to navigate the capsule], [to execute |
| spacewalks], and [to repair damaged solar arrays]." |
| (All three elements are balanced infinitive phrases). |
+--------------------------------------------------------------------------+
Parallelism Across Series and Lists
When presenting a series of three or more items joined by a coordinating conjunction, ensure that every element in the series matches in grammatical category:
- Noun series: "The explorer valued courage, endurance, and ingenuity." (Three abstract nouns).
- Participial series: "Scanning the horizon, adjusting the sails, and monitoring the depth gauge, the skipper navigated the reef." (Three present participial phrases).
- Predicate verb series: "The diplomat entered the chamber, bowed before the assembly, and delivered the ultimatum." (Three past-tense action verbs).
A classic parallelism error occurs when a writer shifts from action phrases to passive nominalizations: "The candidate supported reducing taxes, increasing school funding, and the reform of healthcare." To fix this, change the final element to match the gerunds: "...and reforming healthcare."
Parallelism with Correlative Conjunctions
Correlative conjunctions (not only...but also, either...or, neither...nor, both...and, whether...or) act as precision balance scales. The grammatical structure placed immediately after the first connector must be identical to the grammatical structure placed immediately after the second connector:
- Faulty: "She decided not only [to submit the application] but also [was hoping for an interview]." (Infinitive phrase versus finite verb phrase).
- Parallel: "She decided not only [to submit the application] but also [to request an interview]." (Balanced infinitive phrases).
Advanced Sentence-Combining Strategies
Sentence combining is the systematic art of taking short, repetitive, or choppy sentences and integrating them into fluid, sophisticated prose. In eighth-grade English, you master four primary techniques for sentence combination: embedding appositive phrases, utilizing participial phrases, employing absolute phrases, and deploying subordinating clauses.
+--------------------------------------------------------------------------+
| FOUR SENTENCE-COMBINING VEHICLES |
| |
| 1. Appositive Phrases: Renames a preceding noun with commas. |
| "Marie Curie, [a pioneer in radiology], discovered radium." |
| |
| 2. Participial Phrases: Converts a predicate into a verbal modifier.|
| "[Gripping the wheel tightly], the driver rounded the hairpin turn."|
| |
| 3. Absolute Phrases: Combines a noun + participle to set a scene.|
| "[Her hands trembling with cold], the mountaineer tied the knot." |
| |
| 4. Subordinate Clauses: Creates hierarchies of time, cause, or cond.|
| "[Although supplies dwindled], the garrison refused surrender." |
+--------------------------------------------------------------------------+
Strategy 1: The Appositive Embed
An appositive is a noun or noun phrase that immediately follows another noun to redefine, rename, or explain it. Instead of writing two separate sentences ("Galileo Galilei was an Italian astronomer. He revolutionized observational science with his telescope"), combine them using an appositive: "Galileo Galilei, an Italian astronomer, revolutionized observational science with his telescope." If the appositive provides nonessential information, enclose it within a pair of commas.
Strategy 2: The Participial Reduction
When two actions happen simultaneously or in close chronological sequence, convert the less important action into a participial phrase. Instead of writing: "The architect studied the structural blueprints for hours. She noticed a catastrophic flaw in the foundation," combine them using a present participle: "Studying the structural blueprints for hours, the architect noticed a catastrophic flaw in the foundation."
Strategy 3: The Absolute Phrase
An absolute phrase consists of a noun followed by a participle and any modifying elements. Unlike a participial phrase, which must modify the subject of the sentence, an absolute phrase modifies the entire independent clause, setting an atmospheric scene or zooming in on a physical detail: "The midnight bell tolling in the distant cathedral, the conspirators slipped into the shadows."
Exercises and Solutions
Exercise 1: Diagnosing and Correcting Parallelism Violations. Read the following two grammatically asymmetrical sentences: (A) "The young apprentice was praised for his diligence in the forge, having keen observational skills, and because he respected the master craftsman." (B) "The ambitious venture capital firm wanted neither to invest in unproven software startups nor compromising its financial reserves on speculative real estate." Identify the specific violations of parallel structure in both sentences. Write a comprehensive paragraph explaining the structural clash in each sentence and provide the fully corrected, beautifully balanced versions.
Solution 1: Sentence A violates parallel structure across a coordinated series of three prepositional complements following "for." The first element is a noun phrase ("his diligence in the forge"), the second element shifts to a participial phrase ("having keen observational skills"), and the third element fractures into a subordinate causal clause ("because he respected the master craftsman"). To achieve parallelism, all three elements must take identical grammatical forms, preferably parallel abstract noun phrases governed by the preposition "for." Sentence B violates parallel structure with the correlative conjunctions "neither...nor." The element immediately following "neither" is an infinitive phrase ("to invest in unproven software startups"), whereas the element following "nor" is a gerund phrase ("compromising its financial reserves"). To balance the correlative scales, both elements must utilize matching infinitive forms. The fully corrected sentences read: (A) "The young apprentice was praised for his diligence in the forge, his keen observational skills, and his deep respect for the master craftsman." (B) "The ambitious venture capital firm wanted neither to invest in unproven software startups nor to compromise its financial reserves on speculative real estate."
Exercise 2: Advanced Multi-Sentence Synthesis Challenge. Examine the following four choppy, uncoordinated sentences: (1) "Johannes Kepler was a brilliant seventeenth-century mathematician." (2) "He spent years analyzing the observational records of Tycho Brahe." (3) "His eyesight was deteriorating under the strain of continuous candlelit study." (4) "He formulated three revolutionary laws of planetary motion." Combine all four sentences into a single, cohesive, rhythmically compelling sentence that utilizes at least one appositive phrase, one absolute phrase, and one subordinate clause or participial modifier. Write an analytical paragraph explaining the syntactic mechanics of your synthesis.
Solution 2: "Johannes Kepler, a brilliant seventeenth-century mathematician, analyzed the observational records of Tycho Brahe for years, his eyesight steadily deteriorating under the strain of continuous candlelit study, until he finally formulated three revolutionary laws of planetary motion." To synthesize these four disparate fragments into an elegant, unified sentence, I deployed multiple advanced syntactic techniques. First, I embedded sentence 1 as a nonrestrictive appositive phrase ("a brilliant seventeenth-century mathematician") set off by commas immediately following the proper noun "Johannes Kepler." Second, I utilized the core transitive action of sentence 2 ("analyzed the observational records...") as the main independent predicate. Third, I transformed the physical description in sentence 3 into an evocative absolute phrase ("his eyesight steadily deteriorating under the strain of continuous candlelit study"), attaching a noun ("eyesight") directly to a participle ("deteriorating") to provide poignant sensory atmosphere. Finally, I linked the ultimate intellectual triumph from sentence 4 using a subordinate temporal clause introduced by "until" ("until he finally formulated..."). The resulting sentence eliminates choppy repetition and establishes a dramatic narrative arc within a single syntactic frame.
