Two common mistakes that students make in writing are:

  • run-on sentences
  • comma splices

Run-on Sentences

A run-on sentence is two independent clauses that are connected without punctuation.

  • The weather in summer is beautiful here people come from all over the world to enjoy the beaches.

There are several ways to correct a run-on sentence:

  1. use a period, and start a new sentence
    • The weather in summer is beautiful here. People come from all over the world to enjoy the beaches.
  2. use a comma with a coordinator (and, but, so, or, for, yet, nor)
    • The weather in summer is beautiful here, and people come from all over the world to enjoy the beaches.
  3. use a linking device to make a complex sentence
    • As the weather in summer is beautiful here, people come from all over the world to enjoy the beaches.
