Fused Sentences and Comma Splices: Practice

Comma splices and fused sentences are independent clauses that have not been joined correctly. A word group that can stand alone as a sentence is known as an independent clause. When two independent clauses appear in one sentence, they can be joined in one of many ways.

  1. With a comma and a coordinating conjunction such as (and, but, or, nor, for, so, yet).
  2. With a semicolon (or occasionally a colon or a dash).
  3. Divide the two independent clauses into two sentences.
  4. Consider restructuring the sentences, perhaps by subordinating one of the clauses.

Comma Splices occur when the writer connects two independent clauses with a comma.

Incorrect: Chloe ate her dog food, the brand was Pedigree.

The two subjects, dog food and brand, are connected by an unneeded comma. If a coordinating conjunction were used after the comma, the sentence would be correct.


  1. Chloe ate her dog food, and the brand was Pedigree. (Use a comma and a coordinating conjunction.)
  2. Chloe ate her dog food; Pedigree was the brand. (Use a semicolon.)
  3. Chloe ate her dog food. The kind she ate was Pedigree. (Divide the sentence into two complete sentences.)
  4. The kind of dog food Chloe ate was Pedigree. (Reconstruct  the sentence.)

Fused sentences do not display a comma between independent clauses. As stated before, a fused sentence is also known as a run-on sentence.

Incorrect: The cheerleaders got new uniforms they can not wait for the first game in November.

Revision can be done in the following ways:

  1. Use a period and write two sentences.Correct: The cheerleaders got new uniforms. They can not wait for the first game in November.
  2. Use a semicolon.Correct: The cheerleaders got new uniforms; they can not wait for the first game in November.

Both comma splices and fused sentences can be corrected using the same methods.
