3.2 Sentence Combining and Syntactic Variety
Key Takeaways
- Syntactic variety prevents prose monotony by strategically blending simple, compound, complex, and compound-complex sentence structures.
- Subordination establishes explicit logical hierarchies (such as cause, contrast, or condition), while coordination connects ideas of equal grammatical weight.
- Participial phrases and appositives consolidate series of short, choppy sentences into unified, elegant academic statements.
- Sentence combining requires vigilance against syntactic pitfalls including dangling modifiers, misplaced phrases, comma splices, and faulty parallelism.
3.2 Sentence Combining and Syntactic Variety
Monotony in writing drains an argument of persuasive power. When an essay relies entirely on simple, repetitive sentence patterns, the prose sounds childish and choppy. Conversely, when every sentence is an endless, convoluted chain of clauses, the reader loses track of the core message. Achieving college-level syntactic variety requires balancing sentence structures and deploying combining techniques—such as subordination, coordination, relative clauses, appositives, and participial phrases—to reflect the logical relationships between ideas.
The Imperative of Syntactic Variety
Syntactic variety refers to the intentional variation of sentence length, structure, and opening patterns within a passage. A mature writer uses sentence structure to signal emphasis:
- Short, simple sentences deliver punch, emphasize major conclusions, or create dramatic pauses.
- Complex and compound-complex sentences elaborate on evidence, establish nuanced relationships, and trace cause-and-effect sequences.
By mastering sentence combining, you can eliminate choppy, disconnected thoughts and weave isolated facts into a coherent analytical narrative.
Coordination vs. Subordination: Building Logical Hierarchies
When combining two independent clauses (complete thoughts), you must determine whether the ideas are of equal rank or whether one idea modifies or supports the other.
1. Coordination (Equal Weight)
Coordination joins independent clauses of equal grammatical emphasis using coordinating conjunctions (FANBOYS: For, And, Nor, But, Or, Yet, So) or conjunctive adverbs (however, furthermore, consequently, nevertheless).
- Choppy: The library acquired rare manuscripts. The museum curated complementary artifacts.
- Coordinated: The library acquired rare manuscripts, and the museum curated complementary artifacts.
- Conjunctive Adverb: The library acquired rare manuscripts; however, the museum lacked funding to display them.
2. Subordination (Unequal Weight / Logical Dependency)
Subordination places one clause into a dependent relationship with another using subordinating conjunctions (although, because, since, while, provided that, unless). Subordination explicitly communicates how ideas relate in terms of time, cause, contrast, or condition.
| Logical Relationship | Subordinating Conjunctions | Combined Sentence Example |
|---|---|---|
| Cause / Effect | because, since, as | Because the primary catalyst degraded quickly, the reaction yielded minimal product. |
| Concession / Contrast | although, even though, whereas, while | Although initial funding was modest, the research team completed the project on schedule. |
| Condition | if, unless, provided that | The committee will approve the grant provided that the ethics board certifies the protocol. |
| Time / Sequence | after, before, once, until, when | Once the archives were digitized, global scholars gained unprecedented access. |
Incorporating Relative Clauses and Appositives
Two of the most efficient tools for combining choppy sentences are relative clauses and appositive phrases.
Relative Clauses
A relative clause begins with a relative pronoun (who, whom, whose, which, that) and embeds details directly into a main clause without creating a new independent sentence.
- Choppy: Dr. Elena Rostova led the excavation. She discovered a 4th-century mosaic.
- Combined (Relative Clause): Dr. Elena Rostova, who led the excavation, discovered a 4th-century mosaic.
Appositives
An appositive is a noun or noun phrase that renames or redefines an adjacent noun. Appositives eliminate redundant subject-verb combinations instantly.
- Choppy: William James was a 19th-century psychologist. He proposed the theory of functionalism.
- Combined (Appositive): William James, a 19th-century psychologist, proposed the theory of functionalism.
Deploying Participial Phrases and Managing Modifier Placement
A participial phrase begins with a present participle (-ing) or past participle (-ed / -en) and functions as an adjective modifying a noun.
- Choppy: The engine overheated rapidly. It brought the vehicle to a halt.
- Combined (Present Participle): Overheating rapidly, the engine brought the vehicle to a halt.
- Choppy: The document was written in secret. It was smuggled across the border.
- Combined (Past Participle): Written in secret, the document was smuggled across the border.
The Danger of Modifier Placement Errors
When using introductory participial phrases, you must ensure that the noun being modified immediately follows the introductory phrase. Failing to do so creates a dangling modifier or a misplaced modifier.
Dangling Modifier (Incorrect):
[Walking through the historical archive], [ancient treaties were discovered by the researcher].
--> Problem: "Ancient treaties" were not walking through the archive; the researcher was!
Corrected Modification:
[Walking through the historical archive], [the researcher discovered ancient treaties].
Common Pitfalls When Combining Sentences
When combining sentences on the CLEP exam, watch out for these three major grammatical traps:
- Comma Splices: Joining two independent clauses with only a comma, omitting the required coordinating conjunction ("The storm hit the coast, damage was extensive" -> Incorrect).
- Fused Sentences (Run-ons): Running two independent clauses together with no punctuation whatsoever.
- Faulty Parallelism: Combining elements in a series or comparison using mismatched grammatical forms ("The manager enjoyed planning strategies, analyzing market trends, and to supervise staff" -> Incorrect; should be "supervising staff").
Step-by-Step Sentence Combining Walkthrough
Let us evaluate how four choppy, repetitive sentences can be combined into a sophisticated, fluid passage.
Choppy Input Sentences:
- The city council proposed a new zoning ordinance.
- The ordinance limits commercial development in residential neighborhoods.
- Local business owners protested the decision.
- They argued that the restrictions would harm economic growth.
Revision Strategy Analysis
-
Option A (Focus on Action and Contrast): "Although the city council proposed a new zoning ordinance to limit commercial development in residential neighborhoods, local business owners protested, arguing that the restrictions would harm economic growth." Analysis: This option uses subordination (Although) to frame the council's action, converts Sentence 2 into an infinitive phrase (to limit), and merges Sentences 3 and 4 using a present participial phrase (arguing that).
-
Option B (Focus on Appositive Embedding): "Local business owners protested the city council's proposed zoning ordinance—which limits commercial development in residential neighborhoods—arguing that such restrictions hurt economic growth." Analysis: Option B elevates the business owners to the main subject, embeds the ordinance details in a relative clause between dashes, and concludes with a participial modifier.
Consider the following set of choppy sentences: 'The archival manuscript was recently restored. It was written in 1642. It revealed previously unknown details about colonial trade routes.' Which choice combines these sentences into a single, grammatically correct sentence with proper subordination?
Which sentence demonstrates correct syntactic variety and proper modification when combining ideas about a scientist's breakthrough?
Which revision option best joins the two sentences below to emphasize a relationship of contrast? 'The university expanded its online course catalog. Enrollment in traditional on-campus seminars continued to decline.'
