Example: He felt pain in belly, he ate a large pizza.

This comma splice mistake can be corrected in the following ways:

Correct: He felt pain in belly. He ate a large pizza.

Useful Tips: How to Check for Run on Sentences Errors

how to check for run on sentences

#1. Check if the sentence contains at least two independent clauses

A run-on sentence or comma splice is a sentence that contains two or more independent clauses. An independent clause is a combination of words that makes complete sense without any support of additional clause or phrase. Example of independent clause: He reached office early in the morning nobody was there. There are two independent clauses in the above run-on sentence without any punctuation or any other connecting word.

#2. Check if two independent subjects are available in the sentence

This is another very important tip to identify if the sentence is a fused sentence or has a comma splice issue. In the above run-on sentence, you can see “He” and “Nobody” are two separate subjects without any proper punctuation or connecting word in the sentence.

#3. Check if two independent clauses in a sentence are only separated by a comma
