Run-on Sentences

A run-on sentence is a type of writing mistake. A run-on sentence is a sentence with two or more independent clauses but without punctuation and/or linking word. Here is an example:

  • Tennis is my favourite sport I play it a lot in the summer.

There are many ways to fix a run-on sentence:

  1. use a period, and start a new sentence
    • Tennis is my favourite sport. I play it a lot in the summer.
  2. use a comma with FANBOYS (for, and, nor, but, or, yet, so)
    • Tennis is my favourite sport, and I play it a lot in the summer.
  3. make a complex sentence
    • Because tennis is my favourite sport, I play it a lot in the summer.
