Quick Answer
A restrictive clause is an essential grammatical unit that limits or identifies the noun it modifies. On the Digital SAT, these clauses appear frequently within the Standard English Conventions questions. Unlike nonrestrictive clauses, they are never set off by commas, a distinction typically tested in approximately 2 to 4 questions per exam.
A restrictive clause, also known as an essential clause, is a dependent clause that provides information necessary to identify the specific noun it follows. It is grammatically integrated into the sentence without the use of commas, often following the relative pronoun 'that'.
Question: Which sentence is punctuated correctly for the Digital SAT? A) The painting, that was stolen in 1990, has never been found. B) The painting that was stolen in 1990 has never been found. Solution: B is correct. 'That was stolen in 1990' is a restrictive clause because it identifies which specific painting is being discussed. Restrictive clauses do not take commas.
Mistake 1: Placing commas around 'that' clauses. Students often mistakenly treat all relative clauses as non-essential, but 'that' almost always introduces a restrictive clause requiring no punctuation.
Mistake 2: Over-punctuating based on natural pauses. Students may add commas where they would pause while speaking, rather than following the rule that essential information must remain unpunctuated.
Mistake 3: Misidentifying essential names. Students frequently put commas around names (appositives) that are actually restrictive, such as in 'The director Steven Spielberg,' where the name is necessary to identify which director.
Students targeting 750+ should know that the distinction between restrictive and nonrestrictive often depends on the specificity of the preceding noun. If the noun is already unique (e.g., 'My only sister'), the following clause is nonrestrictive and needs commas; if the noun is general (e.g., 'The sister'), the following clause is likely restrictive and needs no commas.
Appositive
An appositive is a noun or noun phrase that renames another noun right beside it. On the Digital SAT, these frequently appear in the Standard English Conventions questions of the Reading and Writing section. Mastery of appositives is essential, as they typically appear in approximately 10-15% of punctuation-based questions.
Comma Splice
A comma splice occurs when two independent clauses are joined by only a comma without a conjunction. On the Digital SAT, this error is frequently tested within the 'Boundaries' question type in the Reading and Writing section. Students must identify these mistakes to ensure sentences are punctuated according to Standard English Conventions.
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.
Nonrestrictive Clause
A nonrestrictive clause is a descriptive element in the Digital SAT Reading and Writing section that provides non-essential information about a noun. These clauses, frequently tested in Standard English Conventions questions, appear in approximately 15-20% of grammar-based items and must be set off by symmetrical punctuation such as commas, dashes, or parentheses.
Relative Pronoun
A relative pronoun is a word used to connect a dependent clause to an independent clause. On the Digital SAT, these appear frequently in the Reading and Writing section, particularly within Standard English Conventions questions. Mastery of terms like who, which, and that is essential for correcting sentence structure and punctuation errors.
A restrictive clause is a group of words essential to the meaning of a sentence because it identifies the specific noun being described. On the Digital SAT, these clauses are tested in the Standard English Conventions section. They are never surrounded by commas. Identifying them correctly allows students to choose the right punctuation for complex sentences, ensuring the intended meaning remains clear and grammatically sound.
To identify a restrictive clause, try removing it from the sentence. If the sentence's meaning becomes too vague or changes entirely, the clause is restrictive. For example, in 'The students who studied passed,' removing 'who studied' changes the meaning from a specific group to all students. Additionally, look for the relative pronoun 'that,' which almost always signals a restrictive clause that should not have commas.
The primary difference lies in whether the information is essential to the sentence's meaning. A restrictive clause limits the noun and uses no commas. A nonrestrictive clause adds 'bonus' information that can be removed without changing the noun's identity; it must be set off by commas, dashes, or parentheses. On the SAT, choosing between them is a common way to test punctuation mastery.
While the exact number varies by test form, students will typically see approximately 2 to 5 questions that involve restrictive or nonrestrictive elements. These are usually found in the Reading and Writing modules under the Standard English Conventions category. Mastery of this single rule can significantly improve a student's score in the punctuation-heavy portions of the verbal section.
