Are comma splice and run-on sentences the same thing?

Yes, comma splices and run-on sentences are essentially the same thing. Both refer to a sentence where two independent clauses are joined together incorrectly, usually with only a comma.

Here's a breakdown:

* Comma Splice: This is the more formal term used in grammar and writing. It specifically refers to the error of joining two independent clauses with only a comma.

* Run-on Sentence: This is a broader term that describes any sentence where two or more independent clauses are joined together without proper punctuation or conjunctions. This includes comma splices but also sentences that are simply too long and rambling.

Example:

> Incorrect: I went to the store, I bought some milk. (Comma splice)

> Correct: I went to the store, and I bought some milk.

The key takeaway is that both terms refer to the same grammatical error, but "comma splice" is more specific and focuses on the use of a comma, while "run-on sentence" is a broader term that encompasses other forms of joining sentences incorrectly.
