Run-on sentence
A run-on sentence is two complete sentences joined by a simple comma. This is different from a really long sentence. You need conjunctions to fix a run-on sentence. Here’s an example:
- Incorrect: Practice is over at 5pm, you need to pick John up in time.
- Correct: Practice is over at 5pm, so you need to pick John up in time.
You can also replace the comma with a semi-colon or a period to make two complete sentences correctly.
