Quick Answer
A semicolon is a punctuation mark used on the Digital SAT to link two independent clauses without a coordinating conjunction. Appearing frequently in the Reading and Writing section under 'Standard English Conventions,' it typically tests a student's ability to identify complete sentences and avoid comma splices or run-on sentences in 'Boundaries' questions.
A semicolon (;) functions primarily to join two closely related independent clauses that could otherwise stand alone as separate sentences. The standard grammatical rule for the SAT is: [Independent Clause] ; [Independent Clause].
Question: The researcher found the results to be inconclusive _______ she decided to replicate the study with a larger sample size. A) ; therefore, B) , therefore, C) therefore D) ; therefore Solution: The correct choice is A. The semicolon correctly separates the two independent clauses, and 'therefore' acts as a transition followed by a comma.
Confusing semicolons with colons: Students often assume they are interchangeable, but a semicolon requires an independent clause on both sides, whereas a colon only requires one before it.
Using semicolons with dependent clauses: Many students mistakenly use a semicolon to introduce a list or a fragment, failing to recognize that the second part of the sentence must be a complete thought.
Over-reliance on commas: Students frequently create comma splices by using a comma where a semicolon is grammatically necessary to separate two independent ideas.
Students targeting 750+ should know that the SAT considers a semicolon and a period to be grammatically identical in 'Boundaries' questions; if two answer choices are exactly the same except one uses a period and the other a semicolon, both are likely incorrect unless the context specifically demands a different punctuation change.
Colon
The colon is a punctuation mark used on the Digital SAT primarily to introduce lists, explanations, or emphasis. In the Reading and Writing section, 'Boundaries' questions frequently test this mark. A colon must follow a complete independent clause, a specific rule that distinguishes it from other punctuation marks in standard English conventions.
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.
Conjunctive Adverb
A conjunctive adverb is a transition word used to connect two independent clauses on the Digital SAT. These terms, such as 'however' or 'therefore,' appear frequently in the Reading and Writing section under the Boundaries and Transitions question types. They typically require specific punctuation like semicolons or periods to avoid run-on sentences.
Em Dash
The em dash is a versatile punctuation mark on the Digital SAT used primarily to set off nonessential information or provide emphasis. Frequently appearing in the Reading and Writing section under Standard English Conventions, it functions similarly to commas or parentheses when used in pairs to isolate parenthetical phrases.
Independent Clause
An independent clause is a grammatical unit that contains a subject and a verb and expresses a complete thought. On the Digital SAT, this concept is frequently tested in the Reading and Writing section, particularly within Standard English Conventions questions. Students must often distinguish between independent and dependent clauses to avoid punctuation errors like comma splices.
A semicolon on the SAT is a punctuation mark used to separate two independent clauses that are closely related in meaning. On the Digital SAT Reading and Writing section, it is a key tool for fixing comma splices and run-on sentences. It functions similarly to a period but allows for a smoother transition between ideas, signaling to the reader that the two thoughts are intrinsically linked.
To use a semicolon correctly, ensure that the groups of words on both sides of the mark are independent clauses, meaning they can each stand alone as a complete sentence. On the SAT, you will often see a semicolon placed before a conjunctive adverb like 'however' or 'moreover.' The standard pattern is: [Complete Sentence] ; [Transition Word] , [Complete Sentence].
The main difference is that a semicolon must be preceded and followed by independent clauses. In contrast, a colon only requires an independent clause before it; the information following a colon can be a list, a single word, or another independent clause that explains the first. On the SAT, if the second clause doesn't stand alone, a semicolon is always the wrong choice.
While the exact number varies by test form, students can typically expect to see approximately 2 to 5 questions that directly or indirectly test semicolon usage. These questions are usually found in the 'Standard English Conventions' portion of the Reading and Writing modules. Because punctuation is a high-frequency topic, understanding the semicolon is vital for achieving a high score in the verbal section.
