 Run-Ons and Comma Splices

  Remember:    

A run-on (RO) is a sentence structure problem in which two sentences collide into each other and there is no end punctuation to separate them and no conjunction to join them.
A comma splice (CS) is a sentence structure problem in which two sentences are connected with only a comma.  A comma is not strong enough to carry the weight of two complete sentences.

The original sentences lack commas between the independent clauses. Look for a coordinating conjunction that links the two independent clauses.  If there is a coordinating conjunction, there is not a comma splice or run-on error.

Do not confuse the absence of a comma as a sign of a comma splice error.
