SAT Subordination and Clause Emphasis: Controlling Which Idea Stands Out

A main clause can stand alone; a subordinate clause cannot. When you place an idea in a main clause, you emphasize it. When you place it in a subordinate clause, you deemphasize it or show it is less important than the main idea. Choosing whether to subordinate or emphasize an idea is a writing skill the SAT tests: selecting the version that best conveys the author's intended meaning. For example, "Although the vaccine had minor side effects, it proved highly effective" emphasizes effectiveness by putting it in the main clause. The same fact rearranged as "The vaccine proved highly effective despite minor side effects" emphasizes the same idea but suggests side effects are trivial. Both are grammatically correct, but they convey different emphasis.

Common subordinating conjunctions are: because, although, while, since, after, before, unless, if, and when. Using these conjunctions shows relationships between ideas and allows you to control which idea readers focus on. Avoiding subordination (writing "The vaccine had side effects. It proved effective.") removes this emphasis and creates choppy, underdeveloped writing.

SAT revision questions show you a sentence and ask which version best conveys meaning or improves flow. The right answer often involves restructuring subordination to match the passage's emphasis and argument. If the passage emphasizes consequence, use causal subordination ("Because X happened, Y resulted"). If emphasizing contrast, use concessive subordination ("Although X, Y still happened"). If the passage suggests two equal ideas, coordinate them ("X and Y happened") rather than subordinating. This skill requires reading the surrounding passage, not just the isolated sentence, to understand what the author is emphasizing.

Example: A passage argues that social media has both benefits and harms. A sentence saying "Social media provides connection but harms mental health" coordinates both ideas equally. But if the passage later emphasizes mental health as the main concern, revising to "Although social media provides connection, its harms to mental health outweigh benefits" subordinates connection and emphasizes harm, matching the passage's intent.

Over-subordinating—placing too many subordinate clauses in one sentence—creates confusion and obscures meaning. If a sentence has three or more subordinate clauses, consider breaking it into two sentences or simplifying one clause to a phrase. "Although the study found correlation, which was surprising given prior research, the researchers acknowledged that causation remained unclear because the data set was limited" is hard to follow. Better: "Although the study found surprising correlation, the researchers acknowledged that causation remained unclear due to dataset limitations." This version preserves meaning while improving clarity through reduced subordination.

Wrong answers on SAT questions often over-subordinate or subordinate the wrong idea, creating emphasis mismatches. When reviewing practice tests, note which subordination patterns confused you. Usually, the issue is either too many clauses or subordinating the more important idea, making the sentence confusing.

Practice this three-step routine on five sentences daily: (1) Identify the main idea and supporting ideas, (2) Decide which idea the author emphasizes based on the passage's argument, (3) Rewrite to make subordination match emphasis. For example, read a passage, identify its central claim, then revise sentences that subordinate the wrong idea or over-subordinate to fix emphasis. Time yourself: you should complete five sentences in three minutes. This speed and accuracy will transfer directly to test-day performance on subordination questions.

After a week of daily practice, subordination will feel intuitive. You will instantly recognize when a sentence emphasizes the wrong idea and know how to fix it by restructuring subordination.
