Let's learn how to spot run-on sentences and revise them for clear communication!
1. What is a Run-On Sentence?
Definition of a Run-On
(Click to flip for the rule!)
A run-on sentence is two complete sentences punctuated as one sentence.
In a run-on, the thoughts run into each other, making it hard to tell where one idea ends and another begins.
Run-OnI like to eat apples, they are my favorite fruit.
PRO TIP: To spot run-ons, read your writing aloud! A natural, distinct pause usually marks the end of one thought and the beginning of another. If you pause where there is no end punctuation, you may have found a run-on.

4. FYI: The Comma Splice
What is a Comma Splice?
(Click to flip!)
A comma marks a brief pause, but it does not show the end of a sentence.
If you use just a comma between two complete ideas, you create a comma splice.
Comma Splice (Run-On)It is raining outside, I need my boots.
