Comma Rules on the SAT

Hey! I'm prepping for the SAT and I know that comma splices can sometimes show up on the Writing section. Can anyone provide some quick tips/review on comma rules that'll help me avoid errors?

Hi there! Comma usage can be a bit tricky on the SAT Writing section, but understanding a few basic rules will help you avoid common errors like comma splices. Here's a quick overview:

1. Use a comma to separate items in a list (three or more items): "I bought apples, oranges, and bananas."

Note: The serial comma (also known as the Oxford comma) is optional, but using it can help avoid ambiguity.

2. Use a comma to separate independent clauses when they are joined by coordinating conjunctions (FANBOYS: for, and, nor, but, or, yet, so): "She studied hard for the test, but she still didn't feel confident."

3. Use a comma after an introductory word or phrase: "However, she managed to score well on the exam." or "After a long day of studying, she took a break."

4. Use a comma to set off non-essential information or clauses (also known as non-restrictive or non-defining clauses): "The library, which was recently renovated, is a great place to study."

Note: If removing the information would change the meaning, don't use commas: "Students who study well usually perform better on exams."

5. Use a comma to separate coordinate adjectives that describe the same noun: "The large, fluffy dog played happily in the park."

Note: If you can insert 'and' between the adjectives without sounding awkward, you should use a comma.

Remember that comma splices occur when you try to join two independent clauses with just a comma, which is incorrect. To fix a comma splice, you can:

- Use a period and separate the clauses into two sentences

- Use a semicolon (;)

- Use a comma with a coordinating conjunction (FANBOYS)

An example of a comma splice would be: "I want to get an A, I will study all night." You could fix this by using a coordinating conjunction: "I want to get an A, so I will study all night."

Keep these rules in mind as you practice, and you should be well-prepared for the SAT Writing section. Good luck!
