Fused Sentences and Comma Splices

Fused sentences and comma splices result from the writer's difficulty recognizing the basic boundaries of a sentence. The errors themselves arise from lack of correct punctuation. To correct these errors, a writer must divide the sentence into its basic components and then use sentence analysis to punctuate it correctly.

Comma splices occur when the writer connects two independent clauses with a comma:

The two subjects, senses and soul, are erroneously connected by a comma. Had the writer inserted a coordinating conjunction such as "and" after the comma, the sentence would be mechanically correct:

The writer has several other ways to correct the problem:

  1. Place a semicolon between the two independent clauses.   The semicolon creates an implicit link between the ideas in each clause.
    • The senses can be cured by the soul; the soul can be cured only by the senses.
  2. Divide the two independent clauses into two sentences. Note: It is usually beneficial to place an introductory word or phrase before the second sentence; context dictates need.
  3. Make one of the clauses dependent by adding a subordinating conjunction.

A fused sentence can be distinguished from a comma splice in that the fused sentence does not display a comma between independent clauses. A fused sentence is also called a run-on sentence.

Without proper punctuation, the previous sentence is very confusing. With a semicolon, the sentence exhibits maximum clarity.
