What is a run-on?
Run-on sentences
A run-on sentence is a grammatical error that occurs when punctuation is missing at the end of a sentence, causing it to fuse with the sentence that comes after it.
Example of a run-on sentence:
- Incorrect: I climbed up the mountain the view at the top was breathtaking.
A run-on sentence can be fixed by separating the two independent clauses with a semicolon.
- Correct: I climbed up the mountain; the view at the top was breathtaking.
- Note: This is appropriate use of a semicolon because the two sentences are closely related.
A run-on sentence can be fixed by separating the two independent clauses into two sentences.

A run-on sentence can be fixed by separating the two independent clauses with a comma and a coordinating conjunction.
- Correct: I climbed up the mountain, and the view at the top was breathtaking.
