Comma Splice

To correct a comma splice, you can use a period, a semicolon, or add a coordinating conjunction like “and,” “but,” or “so.” Properly addressing comma splices improves sentence clarity and overall writing quality.

Rules for Comma Splices

1. Identify Independent Clauses:
Ensure each part of the sentence can stand alone as a complete thought.

2. Avoid Using Just a Comma:
Do not connect two independent clauses with only a comma.

3. Use a Period:
Separate the independent clauses into two distinct sentences.

  • Incorrect: “She loves reading, she has a vast collection of books.”
  • Correct: “She loves reading. She has a vast collection of books.”

4. Use a Semicolon:
Link the independent clauses with a semicolon.

  • Incorrect: “The sun was setting, we decided to head back.”
  • Correct: “The sun was setting; we decided to head back.”

5. Add a Coordinating Conjunction:
Join the clauses with a comma and a coordinating conjunction (for, and, nor, but, or, yet, so).

  • Incorrect: “He was tired, he went to bed early.”
  • Correct: “He was tired, so he went to bed early.”

6. Use a Conjunctive Adverb:
Connect the clauses with a semicolon and a conjunctive adverb (however, therefore, moreover).

  • Incorrect: “She didn’t study for the test, she still passed.”
  • Correct: “She didn’t study for the test; however, she still passed.”

How to identify a Comma Splice?

1. Check for Independent Clauses:
Read the sentence to see if it contains two parts that can stand alone as complete sentences. An independent clause has a subject and a predicate and expresses a complete thought.

  • Example: “I went to the store, I bought some bread.”

2. Look for a Comma:
Identify if there is a comma separating the two independent clauses.

  • Example: “The sun set, the stars appeared.”

3. Absence of Coordinating Conjunction:
Ensure there is no coordinating conjunction (for, and, nor, but, or, yet, so) following the comma.

  • Example: “She was hungry, she ate a sandwich.”

4. Determine Sentence Flow:
Read the sentence aloud to check for a natural pause. If the pause doesn’t feel like a complete stop but there’s no conjunction, it’s likely a comma splice.

  • Example: “He finished his homework, he went out to play.”

How to correct a Comma Splice

Correcting a comma splice involves ensuring that two independent clauses are properly joined. Here are the main methods:

1. Use a Period:
Separate the independent clauses into two distinct sentences.

  • Comma Splice: “She loves reading, she has a vast collection of books.”
  • Corrected: “She loves reading. She has a vast collection of books.”

2. Use a Semicolon:
Link the independent clauses with a semicolon.

  • Comma Splice: “The sun was setting, we decided to head back.”
  • Corrected: “The sun was setting; we decided to head back.”

3. Add a Coordinating Conjunction:
Join the clauses with a comma followed by a coordinating conjunction (for, and, nor, but, or, yet, so).

  • Comma Splice: “He was tired, he went to bed early.”
  • Corrected: “He was tired, so he went to bed early.”

4. Use a Conjunctive Adverb:
Connect the clauses with a semicolon followed by a conjunctive adverb (however, therefore, moreover).

  • Comma Splice: “She didn’t study for the test, she still passed.”
  • Corrected: “She didn’t study for the test; however, she still passed.”

5. Restructure the Sentence:
Rewrite the sentence to subordinate one of the clauses.

  • Comma Splice: “I enjoy reading, it’s very relaxing.”
  • Corrected: “Because I enjoy reading, it’s very relaxing.”

How to Fix a Comma Splice

Comma splices happens when the structure of the sentences do not match, and you end up with fragments, and run-on sentences. To know how to fix comma splices, here are simple and easy steps to guide you through these unwanted problems.

Step 1: Outline the Sentence

Begin by outlining the sentence structure of the statement with a comma splice. This will help you determine the independent clauses, the common, proper, singular, and plural nouns used in the statement, the verb, the tone, and the context/theme of the sentence.

Step 2: If Both Independent Clauses are Related, Determine the Type of Conjunction

When you have outlined the sentence’s parts, check if the independent clause has a relationship that will require both of them to be in a specific structure or sequence. For example, if the sentence is trying to establish a cause-and-effect relationship then you will need to use a conjunction to fix the sentence. Determine if you will need to use a subordinate or coordinating conjunction to fix the sentence.

Step 3: If Both Sentences Have Little to No Relationship With Each Other, Determine the Appropriate Punctuation Mark

If the sentence’s independent clauses are not related to one another or have little bearing on each other, you must instead remove the comma and replace it with the appropriate punctuation mark. These marks include the semicolon (;) and the period (.).

Step 4: Fix the Comma Splice

After you have determined how you will fix the comma splice, you will need to either remove the comma and insert the correct punctuation mark or add an appropriate conjunction beside the comma. Doing this will turn the comma splice into a complete sentence.
