Quick Answer
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.
A coordinating conjunction is a word that joins two or more grammatically equivalent elements, such as words, phrases, or independent clauses. When used to link two independent clauses, the rule requires a comma to be placed before the conjunction (e.g., Clause 1, [Conjunction] Clause 2).
Question: The research team published their findings in a prestigious journal [ , but / ; but ] they remained skeptical about the long-term implications of the data. Correct Solution: '...prestigious journal, but they...' Explanation: Because 'The research team published their findings' and 'they remained skeptical' are both independent clauses, they must be joined by a comma and a coordinating conjunction.
Mistake 1: Creating a comma splice by placing only a comma between two independent clauses without the coordinating conjunction.
Mistake 2: Treating conjunctive adverbs like 'however' or 'therefore' as coordinating conjunctions, which leads to incorrect comma usage.
Mistake 3: Omitting the comma entirely when a coordinating conjunction is used to join two full independent clauses, resulting in a run-on sentence.
Students targeting 750+ should know that the SAT often provides 'so' or 'but' as an option alongside a semicolon and a conjunctive adverb to test if they can identify the correct logical relationship between clauses while maintaining proper grammatical structure.
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.
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.
Run-On Sentence
A run-on sentence occurs when two independent clauses are fused without proper punctuation or conjunctions. On the Digital SAT, these errors appear frequently within the Reading and Writing section. Mastering this concept is crucial, as approximately 3 to 5 "Boundaries" questions typically test your ability to fix these errors.
On the Digital SAT, a coordinating conjunction is one of seven specific words (for, and, nor, but, or, yet, so) used to link grammatically equal parts of a sentence. They are most frequently tested in the Standard English Conventions portion of the Reading and Writing section. Students must use them with a comma to correctly join two independent clauses and avoid common errors like comma splices.
To use a coordinating conjunction correctly when joining two independent clauses, you must place a comma immediately before the conjunction. For example, in the sentence 'The experiment failed, but the data was useful,' the comma and the word 'but' work together to bridge two complete thoughts. If you are only joining two words or short phrases, a comma is typically not required.
The primary difference lies in punctuation and flexibility. Coordinating conjunctions (like 'and' or 'but') require only a comma when joining independent clauses. In contrast, conjunctive adverbs (like 'however' or 'therefore') require a semicolon before them and a comma after them. Additionally, conjunctive adverbs can be moved to different positions within a clause, while coordinating conjunctions must stay fixed between the two elements they connect.
Typically, you can expect to encounter approximately 2 to 4 questions per Digital SAT exam that specifically test your knowledge of coordinating conjunctions. These usually appear in the 'Boundaries' or 'Structure' question types within the Reading and Writing modules. While the number is small, mastering this concept is essential for achieving a high score in the Standard English Conventions category.
