Comma Splices

A comma splice is a comma that improperly divides (or splices together) two independent clauses (complete sentences). For example:

  • The writing process is very difficult, it combines elements of original thought and time-consuming revision.
  • The Dean of the College was very busy, he could not stop and chat on the veranda.
Notice that in both cases, the part (clause) that comes before the comma can stand alone as a sentence, and the part that comes after the comma can also stand alone.

There are five ways to combine and work with independent clauses; unfortunately, simply inserting a comma between the two is not sufficient. 

Standard Punctuation Between Two Independent Clauses:

  • Period + start a new sentence:
    • Mrs. Pudwhacker likes to sit in the corner. Mr. Jones enjoys petting the chickens.
       
  • Comma + a coordinating conjunction (and, but, for, nor, yet, or, so):
    • Jane does not enjoy the smell of the circus, yet we go every year.
       
  • Simply a semicolon (here you could use a period, but the semicolon adds the proper punctuation and break without completely separating the clauses or the ideas they contain):
    • In spite of severe tornado warnings, Ishmael continues to milk the cows; he is afraid he will run out of cheese.
       
  • Semicolon + a conjunctive adverb (however, moreover, nevertheless, therefore, as a result, consequently...) + a comma:
    • Jane was going to go to the movies; however, she decided to go to the gym instead.
       
  • Rearrange the clauses, making one dependent upon the other:
    • Since I was crying, the old woman took my car.

      OR


      I spilled 28.5 ounces of Dr. Pepper© because I had neglected to put a lid on my cup.
