A run-on sentence, also called a fused sentence, occurs when two or
more independent clauses are put together with no mark of punctuation.
A comma splice is the situation with only a comma between the clauses,
and a comma is not enough to join them.
(Note: An independent clause can stand alone as
a separate sentence; it has a subject, a verb, and makes sense by itself
as a complete thought.)
Example: Laura forgot to set her alarm she was late to work. (run-on)
Example: Laura forgot to set her alarm, she was late to work. (comma splice)
There are five ways to fix run-ons and comma splices. Which you choose depends on the sense of your sentence; there is no one best solution.
