Quick Answer
Subordinating conjunctions are essential words on the Digital SAT that link a dependent clause to an independent clause. These terms, such as 'because' or 'although,' frequently appear in the Reading and Writing section, particularly within Standard English Conventions questions, where they determine logical relationships and proper sentence boundaries.
A subordinating conjunction is a word or phrase that connects a dependent clause to an independent clause, establishing a relationship of time, cause, or condition. The standard grammar rule follows the structure: [Subordinating Conjunction + Dependent Clause], [Independent Clause].
Question: Choose the correct punctuation: ______ the researcher discovered the anomaly she immediately recalibrated the sensors. Options: (A) Because, (B) Because (C) While, (D) Although. Solution: (B) Because. The sentence structure is [Subordinating Conjunction] [Dependent Clause], [Independent Clause]. 'Because' establishes the causal link without needing a comma immediately after the conjunction itself.
Punctuation errors: Students often place a comma immediately after the subordinating conjunction (e.g., 'Because, the rain...') rather than at the end of the dependent clause.
Creating fragments: Treating a clause starting with a subordinating conjunction as a complete sentence (e.g., 'Although he was tired.') instead of attaching it to an independent clause.
Misidentifying logical relationships: Choosing a contrast conjunction like 'while' when the context requires a causal conjunction like 'since' or 'because'.
Students targeting 750+ should know that some subordinating conjunctions, like 'as' or 'since,' can function as both temporal markers and causal markers, and the SAT may test your ability to distinguish these nuances to maintain logical consistency across complex passages.
Coordinating Conjunction
A coordinating conjunction is a word used to connect words, phrases, or independent clauses on the Digital SAT. These seven words—for, and, nor, but, or, yet, so—typically appear in the Reading and Writing section under Standard English Conventions questions, where they are essential for fixing run-on sentences and comma splices.
Dependent Clause
A **dependent clause** is a group of words containing a subject and verb that cannot stand alone as a sentence. On the Digital SAT, these frequently appear in the Reading and Writing section, particularly within 'Standard English Conventions' questions where students must correctly punctuate the relationship between clauses to avoid fragments.
Fragment
A fragment is a group of words that lacks an independent clause, failing to express a complete thought. On the Digital SAT, fragments are frequently tested within the Reading and Writing section under 'Boundaries' questions. Typically, these appear 2–4 times per exam, requiring students to identify and correct incomplete sentence structures.
Subordinate Clause
A subordinate clause is a group of words containing a subject and verb that cannot stand alone. On the Digital SAT, these appear frequently in the Reading and Writing section, particularly within Boundaries and Form questions. Students must correctly punctuate them relative to independent clauses to avoid fragments, a common error on approximately 15% of grammar items.
Transition Word
Transition words are essential linguistic tools on the Digital SAT Reading and Writing section used to link ideas logically. These words, such as 'however' or 'consequently,' appear in the Transitions question type, typically occurring approximately 8 to 12 times per exam, testing a student's ability to identify the logical relationship between two sentences.
A subordinating conjunction on the SAT is a word like 'if,' 'since,' or 'whereas' that joins a dependent clause to an independent clause. These words are fundamental to the Standard English Conventions questions in the Reading and Writing section. They help establish complex logical relationships between ideas, and understanding them is crucial for identifying correct sentence boundaries and avoiding fragments.
You can identify a subordinating conjunction by looking for words that introduce a clause that cannot stand alone as a sentence. Common examples include 'although,' 'because,' 'unless,' 'while,' and 'whenever.' On the SAT, these words often appear at the beginning of a sentence followed by a comma later on, or in the middle of a sentence without a preceding comma.
The primary difference lies in sentence structure and punctuation. Coordinating conjunctions (FANBOYS) connect two independent clauses and usually require a comma before them. Subordinating conjunctions create a dependent clause that relies on an independent clause for meaning. Unlike coordinating conjunctions, subordinating conjunctions can start a sentence, provided the dependent clause is followed by a comma and a main clause.
While the exact number varies by test form, students can typically expect to encounter subordinating conjunctions in approximately 3 to 5 questions per Reading and Writing module. These questions usually fall under the 'Boundaries' or 'Transitions' categories, where the test evaluates your ability to punctuate complex sentences or choose the word that best connects two related thoughts.
