Comma Splice: This occurs when two independent clauses (complete sentences) are joined together only by a comma.
Run-on Sentence: This is a broader term that refers to any sentence that continues without proper punctuation or conjunctions to separate the independent clauses.
Example:
* Comma Splice: The dog barked, he was hungry.
* Run-on Sentence: The dog barked he was hungry and he wanted food so he whined at the door.
Fixing these sentences:
* Use a semicolon: The dog barked; he was hungry.
* Use a conjunction: The dog barked, and he was hungry.
* Use a period: The dog barked. He was hungry.
* Use a coordinating conjunction with a comma: The dog barked, so he was hungry.
