How is a comma splice different from run-on sentence?

The terms "comma splice" and "run-on sentence" are often used interchangeably, but they actually describe the same grammatical error: two or more independent clauses joined together without proper punctuation or conjunction.

Here's the breakdown:

* Comma Splice: This specifically refers to using only a comma to join two independent clauses. This is incorrect because a comma alone is not strong enough to separate the two complete thoughts.

* Run-on Sentence: This is a broader term that encompasses any sentence where two or more independent clauses are joined incorrectly. This includes using no punctuation at all, using a comma where a semicolon is needed, or using a coordinating conjunction without a comma before it.

In essence, a comma splice is a type of run-on sentence.

Example:

* Comma splice: The cat sat on the mat, the dog chased its tail.

* Run-on sentence: The cat sat on the mat the dog chased its tail.

Fixing the error:

You can fix a comma splice or run-on sentence by:

1. Adding a period: The cat sat on the mat. The dog chased its tail.

2. Adding a semicolon: The cat sat on the mat; the dog chased its tail.

3. Adding a comma and a coordinating conjunction: The cat sat on the mat, and the dog chased its tail.

4. Subordinating one of the clauses: While the cat sat on the mat, the dog chased its tail.

Remember: The key is to ensure that your sentences are clear, concise, and grammatically correct.
