Run-On Sentences
A run-on sentence occurs when two or more independent clauses (also known as complete sentences) are connected improperly.
Example: I love to write papers I would write one every day if I had the time.
There are two complete sentences in the above example:
Sentence 1: I love to write papers.
Sentence 2: I would write one every day if I had the time.
One common type of run-on sentence is a comma splice. A comma splice occurs when two independent clauses are joined with just a comma.
Example of a comma splice: Participants could leave the study at any time, they needed to indicate their preference.
Sentence 1: Participants could leave the study at any time.
Sentence 2: They needed to indicate their preference.
Some comma splices occur when a writer attempts to use a transitional expression in the middle of a sentence.
Example of a comma splice: The results of the study were inconclusive, therefore more research needs to be done on the topic.
Sentence 1: The results of the study were inconclusive
Transitional expression (conjunctive adverb): therefore
Sentence 2: More research needs to be done on the topic
To fix this type of comma splice, use a semicolon before the transitional expression and add a comma after it. See more examples of this on the semicolon page.
Revision: The results of the study were inconclusive; therefore, more research needs to be done on the topic.
You can correct a run-on sentence by connecting or separating its parts correctly. There are several easy ways to connect independent clauses.
