SAT punctuation rules help you use commas, semicolons, and other punctuation marks correctly on the digital SAT test. Learning when to use dashes to separate two ideas or how a pronoun connects to a verb will improve your SAT writing score.

Sentences and Clauses

Palm is playing a game.

This is a simple sentence. It has one clause.

Kanto is also playing a game, but not the same game as Palm.

This is a compound sentence. It has two clauses, joined by a conjunction (normally and or but).

Tour and Pete are here, sometimes listening, and they seem happy.

This is a complex sentence. It has three clauses:

  1. the important clause, could be used by itself
    • called an independent clause
  2.  a ‘nonessential’ clause, it is not needed or important
    • called a nonessential clause
  3. a clause dependent on the first clauses
    • called a dependent clause

Punctuation

  • We separate text into sentences.
  • We also have parts of a sentence like words, phrases and clauses.
  • We use punctuation to help understand the sentence.
  • We generally use commas but we also can use colons, semicolons and dashes.

Punctuation Rules

Rules for commas

  • separate list items
  • separate nonessential part of a sentence
  • link two clauses
    • link independent clauses using a conjunction (e.g. and, but, or fanboys)
    • link dependent clauses to an independent clause

FANBOYS – this is an acronym for coordinating conjunctions: for, and, nor, but, or, yet and so

Rules for colons

  • link independent clauses followed by a list or extra information

Rules for semicolons

  • link two clauses
    • link independent clauses without a conjunction

Rules for dashes

  • separate nonessential part of a sentence (e.g. if they have commas)
    • not essential but more part of the sentence meaning

Examples for SAT Punctuation Rules

  • There are three characters—the Scarecrow, the Tin Man, and the Cowardly Lion—that accompany Dorothy on her way to Oz.
  • There are three characters that accompany Dorothy on her way to Oz—the Scarecrow, the Tin Man, and the Cowardly Lion.

SAT Punctuation Rules from Students

Semicolon

a semicolon is like a full stop at least on SAT

semicolons [ used to link two independent clauses without any conjunction.]

The semicolon is only for two related independent clauses.

  • So you can say: Joe cleaned up after him; James didn’t clean up after him.
  • You can’t say: Joe cleaned up after him; the assignment was completed successfully. because those two sentences aren’t related.

Colon

Colon is used when you ask a question and then answer it or when a list is used. Examples

  • My friend says it best: “I like chocolate!”
  • We need 3 things on the adventure: Book, Candy, and Bike.

Coordination and Subordination

coordination [use a comma (,) or a coordinating conjunction (for, and, nor, but, or, yet, so)
(used to link independent clauses)
subordination [use a comma (,) or a subordinating conjunction (eg: although, since, because, while, when, and after),–must use a comma with them (unless sentence begins with independent clause then the dependent clause]

Strategies for SAT Punctuation Rules

Identify Independent and Dependent Clauses

  •  An independent clause can stand alone as a complete sentence.
  •  A dependent clause cannot stand alone and needs to be linked to an independent clause.

Use Correct Punctuation to Link Clauses

  • Use a comma followed by a coordinating conjunction (for, and, nor, but, or, yet, so) to connect two independent clauses (e.g., “…, so…”).
  • Use a semicolon to connect two independent clauses without a conjunction (e.g., “….; …”).
  • Use a comma to separate a dependent clause from an independent clause (e.g., “Although…, …”).

Break Up Run-On Sentences

  • If two independent clauses are fused together incorrectly, consider breaking them into separate sentences or using appropriate punctuation.

Avoid

  • Sentence Fragments: Ensure that each sentence has at least one independent clause.
  • Comma Splices: Do not use just a comma to connect two independent clauses (e.g., “…, …”).
  • Run-off Sentences: Do not connect independent clauses without appropriate punctuation (e.g., “…. ….”).
  • Incorrect Conjunction Use: Do not use conjunctions that are unnecessary or incorrect for the clause structure (e.g., “Although…, but…”).
  • Misuse of Colons and Semicolons:
    • Colons should follow an independent clause and introduce a list or explanation
    • Semicolons should connect two independent clauses.

SAT Punctuation Rules: Simple FAQ

How to use punctuation in the SAT? Use commas to separate items in a list. Use periods to end sentences. Use semicolons to connect two complete sentences.

Should you use a semicolon or period SAT? Use a semicolon when two sentences are connected. Use a period when sentences are separate ideas.

What are the grammar rules for the SAT? Match pronouns to nouns. Put commas around extra information. Make sure each sentence has a verb and subject.

How do you punctuate however on the SAT? Put a semicolon before “however” and a comma after: “I studied; however, the test was hard.”

When do you use dashes on the SAT? Use dashes to separate two parts of a sentence. Dashes work like strong commas around extra information.

Simple SAT Grammar Rules You Need to Know

Basic SAT Grammar Rules: SAT grammar questions test how well you know about punctuation. The College Board makes questions on the SAT that check if you can use commas correctly. A comma is used to separate two complete thoughts when you add connecting words.

What You Need for SAT Prep: Every sentence needs a subject and a predicate to be complete. Questions test if you can find a complete thought. A sentence without these parts is wrong on the SAT or ACT.

How Commas Work: A comma works like a pause in speaking. Put a pair of commas around an appositive – extra information about a noun. The sentence would still make sense if you remove the appositive.

Other Punctuation Rules: Dashes are used like commas but are stronger. A question mark comes at the end of a sentence that asks something. The Oxford comma separates three or more items in a list.

Remember This: SAT reading and grammar work together. A group of words must be complete to be a sentence. Punctuation can also be used to connect ideas or separate parts.
